Health Benefits of Chocolate

May 2019, Final Multimedia Essay

Obesity Rates and Diet

Obesity is rapidly on the rise and has been classified as one of the largest public health issues known today. Obesity is a disease that can cause an individual to be at risk for various other health complications such as type II diabetes, cardiovascular disease and other chronic illnesses. In the Untied States, the population of overweight children has tripled since 1980 causing around two-thirds of the American population to be considered overweight (Albritton, 2010). There is a stark contrast between the health of the population and the modernization of society. It has been shown that as populations continue to grow and society continues to modernize and improve, the health of individuals is on the downfall. Worldwide there has been a six-fold increase in the number of individuals who suffer from diabetes since 1985. In India, it was noted that 11 percent of the population suffers from obesity, whereas in Mexico this was found to be 14 percent (Albritton, 2010). This is in part related to the large increase in sugar and sugar filled substances available to the public. Marion Nestle, found that on average Americans consume around 31 teaspoons of sugar a day, half of this coming from soft drinks (Albritton, 2010). Because of the Industrial Revolution and the advancement of technology, sugar (one of the cheapest food ingredients along with salt and fat) has been used by various companies to increase mass production.  

Just as the sugar consumption has been increasing, there is a rapid increase in salt and fat consumption. Today in the United States, salt consumption has increased by twenty percent over a ten-year period. Consequently, as people increase their salt consumption they look for a substance to quench their thirst, which in many cases is satisfied with sugar beverages; thus, increasing sugar consumption. Additionally, there has been around a twenty-fold increase in fat consumption since 2005 (Albritton, 2010). Because of the rapid increase in chronic disease, the World Health Organization in 2003 enacted certain recommendations for specific dietary intakes. For example, they stated that sugars should not go beyond ten percent of an individual’s daily calorie intake. Despite these recommendations, the junk food business has catered towards children’s craving snacks causing American children to receive around twenty five percent of calorie intake from snacks and therefore a continuous increase in sugar consumption (Albritton, 2010).

Misconception of Chocolate

While most of these sugary, salty and fatty substances come from other junk food brands rather than chocolate, many individuals continue to associate chocolate as a primary cause for the increase in health risks among individuals. Today, chocolate companies have transformed a substance that was once glorified and solely consumed by the elite into one that has become negatively viewed and mass produced. Just as in all other industries, the influence of technology has allowed for chocolate brands to increase their production rate by mass producing a variety of different forms of chocolate. Consequently, individuals have shifted from consuming the rich and pure form of chocolate to consuming a highly processed type that includes the use of more sugar and cheaper ingredients. However, this does not mean that all types of chocolate must be categorized as having a negative impact on an individual’s health but rather that there must be more precaution when choosing what and how much chocolate to consume. Contrary to popular belief, chocolate, can have a wide range of health benefits if the consumer properly selects for the correct type, quality and quantity of chocolate.  

History of Chocolate and Health

Chocolate was first used by the Olmec in 1100 BC. The cacao comes from the tree known as Theobroma Cacao originally found in the Amazon basin. The name itself, originates from the Greek language: Theo which means god and Broma which means drink. The Incas considered this drink to be “a drink of the gods” and therefore the elite were the only ones who were allowed to drink from it (Corti, Flammer, Hollenberg & Lüscher, 2009). They believed the fruit provided wisdom and power while the chocolate drink would benefit their health. The Aztec Emperor Montezuma referred to the drink as “A divine drink which builds up resistance and fights fatigue” (Corti, Flammer, Hollenberg & Lüscher, 2009). Not only did they view cacao as an energy substance but also thought of it as having aphrodisiac properties. It was noted that the Aztec emperor would drink a large amount of chocolate each day before engaging in sexual intercourse (Squicciarini & Swinnen, 2016).

Theobroma Cacao Tree

When the Spaniards discovered chocolate and observed the way the Aztecs used this substance, they soon realized the medicinal benefits the cacao drink could have. The Aztecs would primarily consume this drink before hard labor, in order to avoid getting tired throughout the day (Coe & Coe, 2007). As the discovery of chocolate began to spread, the literature began documenting the health benefits of chocolate. In 1592 the Badianus Manuscript stated that the cocoa flowers had the ability to reduce fatigue. In 1590, the Florentine Codex stated that cocoa could be used to treat fever, diarrhea and heart weakness (Squicciarini & Swinnen, 2016). In 1591 Juan de Cárdenas published the treatise on New World Foods and described that if cacao was prepared a certain way (toasting, grinding and mixing with atole) this could aid in digestion and make an individual powerful and joyful (Coe & Coe, 2007). Soon after the Spanish discovery of chocolate, it was introduced throughout Europe and in 1741 Linnaeus documented the role of chocolate as a source of nourishment, a cure for illness and an aphrodisiac. In 1834 prior to the first chocolate boom, the Dispensatory of the United States stated that chocolate was nutritious and should only be consumed as a drink in the morning as a substitute for an individual’s morning coffee (Squicciarini & Swinnen, 2016).

Although the Aztecs and the Mayas mainly consumed chocolate as a liquid drink, the Industrial Revolution popularized chocolate as solid bars. In 1847 Joseph Fry created the first chocolate bar and soon after the first chocolate boom occurred between 1880-1940, when there was a spike in income and more people began purchasing and consuming chocolate (Squicciarini & Swinnen, 2016). The creation of two key inventions during this time, Hydraulic press and Dutch-process, allowed for diversity in the chocolate making business. The Hydraulic press was used to strip away the fats from the cocoa and produce cocoa butter from the beans. The Dutch-process introduced the alkalization of the cocoa which could change the color of the chocolate products made (Squicciarini & Swinnen, 2016). These key inventions allowed for the creation of different forms of chocolate, which large chocolate companies would benefit from in order to expand their specific brand. Chocolate was soon created in the form of cereals, cakes, ice cream and even lotion. However, chocolate bars continued to be among the most popular type of chocolate consumed in the American economy.

Not only were chocolate bars consumed by children but also by soldiers during the American Civil War. With the new packaging and production of chocolate bars, the soldiers were able to easily and quickly consume this new food product. Similar to the Aztecs, the soldiers took advantage of this energy dense food product. During the war and specifically in times of emergency, the chocolate bars would help provide soldiers an easy and efficient way to sustain themselves throughout battle (Squicciarini & Swinnen, 2016).

Use of Chocolate in the Army

Biochemistry of Chocolate

In addition to energy, chocolate has been studied to provide a large range of health benefits including cardiovascular benefits, insulin resistance, lipid levels, antioxidant effects, mental health benefits and many more. In an interview with Marissa Zarco, MS RDN she noted the key reason for such health benefits comes from the micronutrients found in chocolate specifically flavanols. Mrs. Zarco explained that the flavanols found in chocolate exhibit a vasodilating effect on the human body and therefore can have a positive effect on cardiovascular diseases and blood pressure.

Flavanols are a subcategory of polyphenols which are found in plants and have been proven to alter the function of different pathways in the body. Flavanols are made up of two aromatic rings which are bound together by a three-carbon chain (Farhat, Drummond, Fyfe, Al- Dujaili, 2014). Flavanols can be subdivided into monomers which are called epicatechin and catechin and polymers which are known as procyanidins. The monomers are more common in various different types of fruit and the procyanidins give cocoa the bitter taste (Corti, Flammer, Hollenberg & Lüscher, 2009).  Flavanols have the ability to reduce blood pressure, improve cardiovascular effects through vasodilation, antioxidant effects by reducing reactive oxygen species and improving platelet levels etc.

Health Benefits of Flavanols

Specifically, flavanols activate nitric oxide concentration levels, which can help combat reactive oxygen species and prevent oxidative stress. When the body has too high a concentration of reactive oxygen species such as oxygen free radicals, the body will go into oxidative stress and cause for the development of severe diseases. Therefore, a high flavanol diet will allow for an increase in the nitric oxide concentration which can lead to vasodilation, prevent cell adhesion and platelet aggregation. However, not all types of chocolate contain the same amount of flavanol content because of the reduction in the flavanol levels that occurs as the cocoa beans are processed. (Corti, Flammer, Hollenberg & Lüscher, 2009).  

Three Factors to Consider

When choosing which chocolate to buy, an individual must consider three factors: type, quality, and quantity of chocolate. When choosing the type of chocolate there are usually three options: dark, milk and white chocolate. An individual should aim to choose one that has the highest amount of cocoa with the lowest amount of sugar (Squicciarini & Swinnen, 2016). In order to create the different types of chocolates, they must undergo manufacturing steps and therefore some are richer in flavanols, cocoa nibs, milk or added sugars compared to others.

Dark chocolate compared to milk and white chocolate has the highest number of cocoa solids and lowest amount of sugar and is rich in flavanols. Milk chocolate has a small amount of cocoa solids mixed with a milk substance whether it be condensed or powdered. Lastly, white chocolate is the least pure out of the three, this type of chocolate has no cocoa solids and is instead made up of twenty percent of cocoa butter in addition to a milk product (Squicciarini & Swinnen, 2016).

Three Types of Chocolate

The quality of chocolate is assessed by the number of ingredients, the proportion of ingredients, and the processing methods the chocolate goes through. The key ingredients that are considered are: cocoa solids, cocoa butter, sugar and milk powder. When choosing a chocolate an individual should pay close attention to the label and determine the proportion of cocoa nibs compared to all other ingredients (Squicciarini & Swinnen, 2016).

Cocoa Nibs

Lastly, the quantity of chocolate is important when analyzing the nutritional benefits. In the past, many nutritionists recommended individuals who were suffering from obesity and/or trying to lose weight to completely eliminate chocolate from their diet. However, today nutritionists have realized the importance of chocolate in protecting the human body from severe diseases or a state of oxidative stress and therefore have emphasized the need to restrict the amount consumed rather than completely eliminate it. Studies have shown that small doses of 5-10g daily of dark chocolate can positively enhance human health whether it be through anti-inflammation, hypertension, and/or altering plasma lipid levels (Squicciarini & Swinnen, 2016).

Overindulgence of Chocolate

Blood Pressure

Moderate consumption of dark chocolate can help with lowering blood pressure. A study conducted with the Kuna individuals stated that because of their high levels of consumption of chocolate beverages they exhibited remarkably low blood pressure states. However, after further investigation it was noted that this study was not properly conducted and the correlation between the levels of chocolate consumption of the Kuna individuals and blood pressure was not accurate (Howe, 2012). However, this is not to say that current studies have not found a correlation between chocolate consumption and blood pressure.

It has been shown that a regular intake of dark chocolate promotes blood vessel dilation because of the effect of polyphenols on increasing nitric oxide concentration and thus lowering blood pressure (Squicciarini & Swinnen, 2016). Additionally, chocolate has some levels of potassium which can result in the release of sodium ions therefore aiding the regulation of blood pressure levels. The Rusconi et al. (2012) study assed the relationship between different types of chocolate and blood pressure. The study recruited a group of adult males and had them consume a certain amount of either dark or white chocolate every day. Over the course of 28 days they noticed a decrease in blood pressure in the participants who only consumed dark chocolate (Squicciarini & Swinnen, 2016).

Plasma Lipid Levels

Chocolate can also improve an individual’s plasma lipid levels. Specifically, cocoa butter found in dark chocolate contains oleic acid which is said to affect lipid levels. Cocoa butter has been found to increase HDL cholesterol, decrease LDL cholesterol and decrease the availability of triglycerides in the human body, which can then have a positive effect on the presence of cardiovascular diseases. A study found this to be true after a group of participants consumed around 75g of dark chocolate a day for three weeks. While this did not hold for the consumption of white chocolate, when assessing milk chocolate the researchers also found there to be a decrease in the triglyceride levels and an increase in the HDL cholesterol levels (Squicciarini & Swinnen, 2016).

Mental Health

Chocolate can have an impact on mental health and cravings. Because chocolate contains highly branched amino acids, there can be an increase in the amount of serotonin released. Serotonin is neurotransmitter that is linked to depression: low levels of serotonin can increase depression. Therefore, by increasing serotonin levels, chocolate can help improve an individual’s mood. This can be observed throughout a women’s menstrual cycle. During this time a women’s progesterone levels decrease and their cravings for chocolate increase; thus, combatting the effect of depression during this time (Squicciarini & Swinnen, 2016).

Chocolate and Mood


Although there is a rapid rise in obesity rates and chronic diseases it is incorrect to generalize this to the effect of chocolate products. As shown, there are a great amount of studies that have been conducted in order to explore the health benefits of chocolate. While it is true that chocolate can negatively impact human health, this is not always the case. By focusing on the three factors: type, quality and quantity when consuming chocolate an individual protects him/herself from the negative effects that can be seen when someone over consumes chocolate that has high amounts of sugar and other cheap ingredients. While, most studies focus on dark chocolate and its health benefits there should be more research focused on how to make this type of chocolate more accessible to the entire population. A valuable food product such as chocolate, should not only be restricted to the elite, as it once was with the Aztecs and Maya, but rather consumed and enjoyed by all.

The Industrial Revolution: The Transformation of Chocolate from a Rare Delight to a Global Commodity

Industrialization greatly improved the quantity, quality, and variety of food of the working urban populations of the Western World. This development was due to reasons which were two-fold: first, historical developments such as colonialism and overseas trade were structures which inspired this process, and second, specific technologies such as preserving, mechanization, retailing, transport, and the growth of the commercial catering business allowed for the distribution and access of chocolate to flourish. Technologies which were developed from the Industrial Revolution greatly changed the worldwide consumption of chocolate, greatly increasing the quantity and ease of its production and distribution and subsequently increasing the ease and diversity of consumers’ access to chocolate products.

The Industrial Revolution began in England in the early 19th century, and stemmed from factors such as a smaller population and thus a need for a more efficient workforce. Prior to industrialization, the majority of people in Europe subsisted on peasant farming and leasing land from the elite (Dimitri et al. 2). In the latter half of the second millennium A.D., voyages of discovery around the globe sparked colonialism in foreign lands soon thereafter. There were various philosophies in justification of colonialism; one was that of social evolutionism and intervention philosophies, or the idea that natives were incapable of governing themselves and in need of outside intervention. According to research published by M. Shahid Alam of Northeastern University, industrialization of countries across the world was unequal; some countries underwent industrialization centuries prior to others (Alam 5). The reason for this was partially due to the fact that some countries colonized other countries for their own imperial or industrial benefit, so the colonized countries themselves could not go undergo industrialization at that time. Great Britain, Spain (and subsequently Portugal), and France were a few imperial superpowers which underwent industrialization first and each dominated many colonies.

Because of the far-reaching, global geography of these mother countries’ colonies, the colonial economy depended on international trade. For example, the British empire depended on the American colonies’ production of goods, as did the colonies on the goods of the British Empire. Merchants sent out ships to trade with North America and the West Indies; in 1686 alone, over 1 million euros of goods were shipped to London (“Trade and Commerce”). While wool textiles from England’s manufacturers that spurred from the Industrial Revolution were shipped to the Americas, the colonies shipped goods such as sugar, tobacco, and other tropical groceries from its plantations back across the pond. Due to Europe’s incredibly high demand for some of these American goods, the slave trade developed to meet Industrialization’s hefty needs for cheap labor (“Trade and Commerce”).

A few hundred years later, significant agricultural technologies spurred from industrialization. By the early 1900s, most American farms were diversified, meaning that various animals and crops were produced on the same cropland in complementary ways. However, specialization was a method which developed in farms at around this same time, used to increase efficiency by narrowing the range of tasks and roles involved in production. This way, specialized farmers could focus all their knowledge, skills, and equipment on one or two enterprises. Furthermore, mechanization allowed for the tremendous gains in efficiency with getting rid of the need for human labor with routine jobs such as sowing seeds, harvesting crops, milking cows, and feeding and slaughtering animals. Within the 20th century only, the percentage of the U.S. workforce involved in agriculture declined from 41 percent to 2 percent (Dimitri et al. 2). This greatly increased the efficiency of the production of ingredients which go into chocolate such as milk, cacao, sugar, salt, and vanilla from their respective farms.

In addition to farming technologies such as specialization, methods such as preserving, mechanization, retailing (and wholesaling), transport, and the growth of the commercial catering business improved the quality of the chocolate product itself and lessened the amount of time many large chocolate companies produced these chocolates drastically (Goody 74).

The mechanism of preserving was spearheaded by Nicolas Appert, who developed a process called canning (“bottling” in English) in response to conditions in France during the Napoleonic Wars, when the preservation of meat was important for feeding on-the-road soldiers (Goody 75). Glass containers were also developed around the same time to preserve wine and medicine. Methods such as artificial freezing as well as salt — which became such a popular form of preservation that a “salt tax” was eventually implemented — also developed to preserve foods. Pickling inside vinegar, as well as sugar, which was used to preserve fruits and jams, were also methods which advanced. This, in turn, also caused the imports of sugar to rapidly increase during the 18th century (Goody 75). With preservation mechanisms highly developed compared to before, chocolate products could finally be distributed from manufacturers and remain on shelves for quite some time — it did not necessarily need to be fresh to be sold and readily available to consumers.

Additionally, the process of mechanization was the manufacture of many processed and packaged foods, and this process was furthered by Ford’s assembly line and interchangeable parts. Through these technologies, packaged foods and products could be produced much more quickly and efficiently at greater quantities. This greatly increased the production efficiency and quantity with which packaged chocolate could be distributed, allowing for the proliferation of the some of the biggest mass-brands in chocolate production, such as Hershey’s and Nestle (Goody 81).

Furthermore, the process of retailing was marked by the shift from open market to closed shop; this process began as early as Elizabethan times. Back in the Elizabethan era, great efforts were made to ensure that there were no middle men in terms of sales and that there was no resale at higher prices. Eventually, however, grocers overtook the import of foreign goods. Just as imported goods became cheaper with the new developments in transport, so too did manufactured goods and items packaged before sale came to dominate the market (Goody 82-3). This allowed many various chocolate products from manufacturers all across the world to hit the shelves of grocers, readily available to consumers of any city in the United States. These products were generally branded goods, “sold” before sale by national advertising. Advertising itself, additionally, led to the homogenization of chocolate consumption, allowing similar brands of chocolate products to be distributed across the U.S. This even led to the eventual homogenization of American taste preferences for chocolate; because the Hershey’s chocolate bar was so heavily distributed and popularized, eventually, Americans were unaccustomed to anything that did not have Hershey’s uniquely sweet and salty taste (“Here There Will Be…” 108).

The final large component of industrialization which greatly increased chocolate production and distribution was the revolution of transportation. Rail transport provided the masses with cheap and wholesome food; in fact, there were certain periods of time during the Industrial Revolution in which U.S. railways were transporting goods more than people (Goody 82). Last but not least, the growth of the commercial catering business led to the decline of the domestic servant. This decline of the domestic servant also allowed English families to explore quick, sweet recipes incorporating chocolate such as brownies, cookies, and cakes.

Bigger-picture progressions in history such as colonization and international trade connected the world economy and allowed for technologies such as preserving, mechanization, retailing, and new transport to grow and flourish. These methods, in turn, caused global companies such as Hershey’s and Nestle to revolutionize the production and distribution of chocolate into a massive, global business. What was once enjoyed by the few and wealthy was now easily accessible by the masses, homogenizing the tastes of Americans to a few specific chocolate brands. None of this impact on chocolate products’ consumers and producers alike would have been possible without the historical and technological developments of the Industrial Revolution.

“We have more Chocolate”: Chocolate Innovation in the Industrial Revolution.

Chocolate Industry Before the Industrial Revolution

The industrial revolution took place about 1760 to 1850, all across Europe (especially Great Britain), and the United States (especially New England) (Allen, 2011).  When most think of revolution they envision an oppressed people abruptly overthrowing the existing government and starting a new system of government.  Like the American Revolution or the French Revolution, or the revolution that’s currently taking place in Venezuela.  The industrial revolution was certainly a transition to a new system or way of producing things, but I like to think of it as more of an era of direct or indirect collaboration and healthy competition 😊 .  I guess the industrial collaboration and competition just doesn’t have the same “oomph” to it.

The industrial revolution represented a transition to new manufacturing processes in many different sectors, that had previously been done manually or by hand (Allen, 2011). 

Increase and efficient use of steam and water power, chemical and iron manufacturing and the development of machine tools and culminating in the mechanized factory system (Wikipedia, 2019).  It also led to a sustained increase in population and economic growth.  The textile industry primarily benefited from the Industrial Revolution, but the Chocolate industry certainly benefited from this era of innovation (Wikipedia, 2019).

Chocolate in different simple forms had been produced for consumption for Europe and the United States since its Spanish “discovery”, from the Mesoamerican peoples, in the 16th century (Coe & Coe, 2013).  Spain had long had a monopoly on chocolate production and kept the price point high so when it was first introduced to other countries, only the wealthy could afford to buy it (Walter Baker & Co., 1884).  This likely delayed an increase in chocolate production and also chocolate manufacturing and product innovations.

The processing of the raw material of cacao beans to edible chocolate had not changed significantly; roasting, winnowing, grinding, and milling (Leissle, 2018).  Most of the process was done manually using simple devices and on a small scale.  There was large scale chocolate production going on but that was producing chocolate in just wafer form for beverages and still done by hand.  Like any developing industry, chocolate product costs were high, and there was not much availability or product variation (Coe & Coe, 2013).

Revolution is in the Air and in the Chocolate

One of earliest documented uses of power machinery being utilized for chocolate production was by Dr. James Baker of Dorchester Massachusetts and John Hannon of Ireland (Walter Baker & Co., 1884).  Hannon was a chocolate maker.  Dr. Baker had some knowledge of the cacao bean and chocolate and provided the funding for the startup business. Together, in 1765, they rented space in a grist mill in Milton Lower Falls, Massachusetts and ground cacao beans using hydro power (Coe & Coe, 2013).  Previously, the grist mill had been used for flour for many years.

In 1772, Dr. Baker and Hannon marketed and sold their product as Hannon’s Best Chocolate, in the cake form.  In 1799, Hannon disappeared en route to the West Indies and Dr. Baker continued the chocolate business under his name (Coe & Coe, 2013).  Imagine starting and growing ANY type of business during the American Revolutionary War, near Boston, Massachusetts.  Incredible.

A Revolution Takes Time

What many do not remember or never fully learned, was that Independence Day (4th of July), was the date (July 4, 1776) that the 13 colonies of America, declared their independence from Great Britain (Wikipedia, 2019).  The Revolutionary War continued for another 7 years until 1783 when the Paris treaty was signed (Wikipedia, 2019).  A revolution takes time.

In 1820, Dr. Baker’s grandson Walter, took over the business and the chocolate company was reorganized with other contributors and investors under the name of the Walter Baker & Company (Coe & Coe, 2013).

It produced many chocolate products like unsweetened cocoa powder and sweetened chocolate (named for John German (Walter Baker & Co., 1884)) for baking, dipping and candy making.  Or any of their recipes.

Another major milestone for chocolate production was accomplished by Coenraad Johannes Van Houten in Amsterdam in 1828 (Coe & Coe, 2013).   Instead of boiling and skimming to remove the cacao butter from the chocolate liquor, he developed a mechanized hydraulic press for that process function (Coe & Coe, 2013).

Early cocoa press in Van Houten’s Factory, using manual labor (Coe & Coe, 2013)
Houten’s Mechanized Hydraulic Press

Van Houten used the mechanized hydraulic press to press the fat from roasted cacao beans (Coe & Coe, 2013).  This hydraulic process created a cacao cake which then could be pulverized into cacao powder, which could be used in all manufacturers.

Van Houten also innovated the use of alkaline salts to remove the bitter taste and made it more water soluble.  This is known as Dutching (Coe & Coe, 2013).  Baker did not approve of Dutching or adding anything, including chemicals, to cacao.  He believed the chemical process diminished the natural aroma and flavor of the cacao seeds (Walter Baker & Co., 1884).

Joseph Fry and his legacies had been making chocolate in Great Britain since 1728.  In 1789, Fry purchased Watt’s steam engine (The steam engine was perfected by James Watt in the late 1700’s, for many different industrial applications) to be the motive force to grind his cacao beans, instead of hydro power (Coe & Coe, 2013).

In 1847, The Fry Company went on to create a blend of cocoa powder and sugar with melted cacao butter, instead of warm water, so a thinner viscous chocolate could be cast into a mold. This was the world’s first true eating chocolate, not brittle and dry as before (Coe & Coe, 2013).

Van Houten and Fry Take Production Skyward

With the Van Houten processing break through, and Fry perfecting a way to mechanize the grinding process, and other companies following suit,  overall chocolate production on both sides of the Atlantic was able to increase substantially and meet consumer demands (Coe & Coe, 2013).

There were other chocolate innovations during the Industrial Revolution.

Such as, in 1826, Swiss Phillipe Suchard, began making chocolate with his invented machinery which included the world’s first melangeur or mixing machine (Coe & Coe, 2013).

Innovation Continues

And just because the Industrial Revolution ended, chocolate manufacturing processes continued to improve and innovate, and the chocolate product continued to be refined to satisfy all consumers tastes and thereby increase chocolate production.

In Great Britain, the Cadbury Brothers, who had a long history of making innovative chocolate and cocoa products, would always be competing with Fry to outdo each other with new product and gain more market share (Coe & Coe, 2013).

In 1867, Henri Nestle’ and Daniel Peter worked together to create the first milk chocolate bar. Peters, a swiss chocolate manufacturer came up with the idea of using Nestle’s invented powdered milk in his process (Coe & Coe, 2013).

In 1879, Swiss Rudolph Lindt invented the conche machine and the conching process.  Conching is the process of rolling chocolate liquor and using that frictional heat to achieve a desired taste and smoothness. Chocolate was no longer coarse or gritty.  Chocolate consumers loved it.  Lindt called this chocolate fondant and the conching process became the standard for making chocolate (Coe & Coe, 2013).   

And in 1903, like Thomas Edison or Henry Ford, Milton S. Hershey, would bring all the product and process development and innovation, together, that occurred before his time, and launch his chocolate company (Coe & Coe, 2013).  

Over the many years, chocolate of all types, used in all applications were produced at lower and lower prices, and chocolate “went viral”.   Adults and children everywhere can’t get enough of chocolate (and sugar, which has been a prevalent ingredient in chocolate and also has driven chocolate consumption (Mintz, 1986)).

Trending Chocolate Consumption

In 1830, both in the U.S. and U.K., we were eating about 3/5  oz. per capita (Walter Baker & Co. Ltd., 1917).  In 1860, the U.S. and U.K were eating about 2 oz.  per capita (Walter Baker & Co. Ltd., 1917).  By 1915 we were eating over 30 oz. of chocolate per capita (Walter Baker & Co. Ltd., 1917).  Clearly, we have loved chocolate and the companies and innovators of the industrial revolution learned to make a lot of inexpensive and a variety of quality chocolate for us. 


And that love relationship continues with the world today. In 2015, just in the U.S. alone, we ate 9.5 lbs. per person per year.

World’s Biggest Chocolate Consumers in 2015

So the next time you tear open a Ghirardelli dark chocolate square, or unwrap a Hershey chocolate kiss, or a nice someone uses Baker’s Chocolate to actually bake you chocolate frosted chocolate cupcakes for your birthday…..before you devour that sweet mind altering chocolate treat, maybe tip your hat or give props to the chocolate industry innovators of the industrial revolution.  They certainly enabled modern day chocolate manufacturing processes like the ones featured in this YouTube video by Tesco (Tesco, 2015).

The Revolution of Industry and Chocolate

In the 18thcentury, the transition from using human, animal, or water power to the burning of fossil fuels brought about a period of great change.  This change was called the Industrial Revolution, and was built on large deposits of coal and iron that were used to fuel advances in the technologies and factories responsible for manufactured goods. What headlined this Revolution was the arrival of an improved textile industry, steam powered transportation, and mass production. What is less discussed, however, is the effect that the Industrial Revolution had on the chocolate industry.

Previously, chocolate was considered in Europe and America as an exclusive drink for the elite and wealthy; either consumed in a cup at breakfast or during the day as a snack (Martin 2010).  Chocolate maintained a very polarizing reputation for its multifaceted uses. Some, like Benjamin Franklin, believed that it could be used as a treatment for smallpox (Martin 2010). Others associated it with being an aphrodisiac and others believed that the “exchange of chocolates between a man and woman was tantamount to a declaration of love,” (Quélus).  The reputation of chocolate and the invention of new production technologies enabled this exclusive commodity to become available to all people, leading to an increase in popularity of the product and profit from its sales.   

above is a picture of a conch used in Switzerland, Ammann was one of the first manufacturers to make conches available to chocolate produces in the late 19th century

The cocoa press and the conching machine are two of the biggest innovations that empowered the chocolate industry during the Industrial Revolution.  In 1828, Coenraad van Houten patented the cocoa press. This press burned coal to produce heat that would create enough steam and pressure to power the machine, which was a type of hydraulic press.  This process would separate fat from roasted cacao beans, and this butter would be pulverized into a fine powder called cocoa that would later be used to create solid chocolate (Coe & Coe). The cocoa press allowed a quick, inexpensive method of creating a chocolate drink, and this invention began the process of opening the window of accessibility.   The Conch Machine was the next invention to increase the accessibility of chocolate while also approving its taste and appearance. Invented in 1879 by Rodolphe Lindt, the conch was a machine that was built to give chocolate a texture that was easier to mold and preferable the solid chocolate currently in the market eaten (Giller 2017). This chocolate was described as gritty and crude, while the chocolate produced by the conch was tasty, smooth, shiny, and had a superior aroma.  The original conch consisted of a granite parts that would mix ingredients from as little as six to eighty hours at a time.  Secrets of the conch were so sought after that many manufacturers like Lindt either kept their methods a secret or to claimed the details of the process were “proprietary” (McClements 654). 

The final innovation that truly transformed the chocolate industry was the use of the assembly line.  The video above shows how manufacturers specialized the production of chocolate.  While some workers, like Lucy and Ethel, wrap the chocolates, other workers further down the assembly line will package the wrapped chocolate. Tasks were separated and specialized like this to create the most efficient production process possible.  In 1903, Milton S. Hershey founded a chocolate company that would be known for employing these principles from the Industrial Revolution.  Hershey’s Kisses offered a consistently identical product that could be efficiently mass produced.  Customers were guaranteed that when they unwrapped the foil, they would be met with a tasty milky chocolate that would satisfy the customer every time.  These principles put in place by Hershey showed the beginnings of the chocolate industry as we know it as today.

This except from the popular television show, “I love Lucy” also shows that chocolate has played a role in the culture of our society.  While the video makes most viewers laugh at the small expense of manufacturing companies, its true purpose is to promote chocolate.  Richard Cadbury revolutionized the chocolate industry with his chocolate’s association with heart boxes and Valentine’s day. In 1859, Cadbury introduced his own brand of chocolate, and over the next decade he began to package his chocolate into heart shaped boxes. Heart shaped boxes were previously used for betrothal jewelry, sewing materials, and porcelain. By filling these boxes with his chocolate and associating them with Valentine’s Day, Cadbury had struck cacao gold. Sales skyrocketed because of the already present reputation of chocolate as being more feminine, an aphrodisiac, and a token of love.  Over a hundred and fifty years later and chocolates are still associated with Valentine’s Day, are still gifted to women, and still presented in heart shaped boxes.

In conclusion, the Industrial Revolution made chocolate accessible to more than just the elite and rich of Europe and America. Inventions during the Revolution increased the efficiency of producing chocolate as both a drink and a solid, while the assembly line further increased the mass production of identical products. Without the Industrial Revolution, we would not experience the same chocolate industry that we have today.

The History of Chocolate: A Story of Mass Democracy or Mass Exploitation?


A traditional view of the history of chocolate focuses on the growth in mass consumption of chocolate as a byproduct of democratization and the industrial revolution. With time, consumption of chocolate spread from Aztec elites to the European nobility to the common citizens of the Western world. However, I contend that the history of chocolate is not simply one of expanded access fueled by increased political and economic inclusiveness, but rather one of shifting patterns of exploitation. The expansion of chocolate consumption has tracked the political enfranchisement and growth in economic power of white Westerners, but has simultaneously resulted in the brutal exploitation of poor brown and black people, first in Latin America, and now in Africa.

The Elite Origins of Chocolate

In ancient Aztec society, the consumption of chocolate was confined to the elites, which included members of the royal house, lords and nobility, long-distance merchants and warriors. Consumed after dinner at royal banquets, it was considered an exotic delicacy and a gift from the gods, a precious treasure not to be wasted on commoners (Coe and Coe, pg. 95). It was also used in religious ceremonies, including marriage rites, to symbolize the sacred nature of matrimonial covenants (Coe and Coe, pgs. 97-101). When the Conquistadors brought chocolate back to the Old World from Mesoamerica, it quickly spread through Europe, becoming a delicious treat for European nobles. Through the displays and pageants of Spain’s Habsburg rulers, the drink quickly gained fame, with powerful oligarchs such as Cosimo de’ Medici becoming “chocoholics” (Coe and Coe, pg. 135). Curiously, chocolate came to be seen as more feminine, as it was popularized with ladies of the royal courts in Europe. It retained its association with marriage, as women intermarried among royal families and brought their love of chocolate with them (Coe and Coe, pgs. 136-137).

The image below displays the status of chocolate drink as both an elite status symbol and a beverage uniquely associated with the idealized image of the noble lady and her well-ordered household:

Chocolate Comes to the Masses

Despite chocolate’s elite origins, a different narrative took form around chocolate as production methods were refined and it became more broadly available to the masses. By the late 17th century in England, chocolate became associated with the intellectual movement towards democratic governance during the Enlightenment era. Chocolate houses and coffee houses became centers of democratic thought, prompting Charles II to issue an ultimately futile decree to close them down in 1675 (Coe and Coe, pg. 168). Chocolate was truly democratized in the mid-19th century, as technological innovation during the Industrial Revolution made chocolate far more accessible to ordinary people. In 1828, Coenraad Johannes Van Houten invented the alkalizing process which gave chocolate its familiar dark color and made it milder in flavor. In 1849, Joseph Fry invented the modern chocolate bar, using cocoa butter to transform chocolate into a solid confection (Coe and Coe, pgs. 234 – 241). Simultaneously, sugar, which had come into common usage as both a preservative and an ingredient to supplement the caloric needs of working and middle class citizens in the West, came to be one of the most important components of both chocolate drink and the newly invented bars (Schartzkopf and Sampeck). As the narrative goes, the physical transformation of chocolate represented a revolution in accessibility, carried on a wave of political democratization and the industrialization-fueled growth in mass consumption.

The picture below displays three different styles of modern, mass-produced chocolate bar, complete with sugar for extra flavoring and the familiar dark coloring introduced by Van Houten’s method:

Modern, mass-produced chocolate bars complete with unique design elements

The Thin Veneer of Democracy

Though the history of the spread of chocolate is often portrayed as a triumph of mass democracy, in truth chocolate has been and continues to be a product of extremely unequal, hierarchical systems of racial and class-based oppression, in which poor brown and black people produce chocolate as a luxury good to be enjoyed by better off, mostly white Westerners. The oppressive hierarchies of Western chocolate production trace their origins to the encomienda system of the early 16th century, in which Spanish colonizers virtually enslaved the Native people of their American colonies, forcing them to harvest cash crops such as chocolate beans, often at the expense of their own lives (Yeager). Eventually, the encomienda system came to an end, and chocolate production in the New World gradually became the domain of newly enslaved Africans. As globalization increased, and outright slavery fell out of favor, production shifted from Latin America to Africa, with (technically illegal) slave labor still being used to produce chocolate in places such as Sao Tome as late as the early 20th century (Satre). In the modern era, the exploitation of African labor continues. 74% of chocolate was produced in Africa during the 2016-2017 season, but Africans only consumed a tiny percentage of the chocolate they produced, and received a comparatively small cut of the profits (Leissle, pgs. 4-7, 36-46). In the words of Ghanian farmer Mercy Asabea, when asked about the local scarcity of chocolate, “Ghana made Europe what it is…We have every resource here, yet Ghanians are not progressing at all” (Leissle, pg. 57).

The following chart shows a harrowing picture of the relationship between modern chocolate production and consumption, with the orange dots representing main exporters and the red dots representing export destinations:

Modern chocolate production and consumption patterns (April 2010 to March 2011)

Accusations of highly exploitative labor practices, including forced child labor, continue to this day. This video from the Stolen Lives Project details just a few of the abuses allegedly committed by the modern day chocolate production industry:


Ultimately, it is important for us to develop a realistic perspective on chocolate and its origins. One can both appreciate the expansion of access to this delicious treat, especially in the Western world, yet simultaneously reject purely Western-centered narratives which exclude the experiences of disadvantaged black and brown people in the developing world as they relate to chocolate production and consumption

The Industrial Revolution: Chocolate for All!

Take a moment to Imagine not having access to the luxury of indulging in chocolate. It’s hard to believe that prior to the Industrial Revolution, chocolate was considered more of an elite privilege that was practically out of the common man’s reach. This was partially due to the fact that the cost of growing and producing chocolate was extremely high –  it was a laborious and time-consuming task, and only the earnings of the elite could support consumption on a regular basis. The Industrial Revolution birthed the modernization and development of chocolate production through mechanization, completely changing the effects around consumption. The Industrial Revolution lowered the production cost, increased efficiency, and improved taste, texture, and appearance of the product as a whole. Today, chocolate is everywhere! From well-known candy bars such as Hershey’s, and Mars (currently known as the Milky Way bar), to chocolate syrup mixed into mocha’s that is available at almost every coffee shop. For the purpose of this blog post, I would like to touch on a few of the incredible advances in the chocolate making industry made possible by the Industrial Revolution: the conche, winnowing machine, hydraulic press, and the marriage of chocolate and sugar.

Often referred to as the “food of the gods,” cacao was used by the Maya, Aztec, and Spanish to create a chocolatey drink that would most likely taste pretty bitter and unappealing compared to the endless forms, tastes, and textures available to us today. However, by the time the Industrial Revolution occurred, a man by the name of Rudolf Lindt was also craving something different – an indulgence that was far less coarse and gritty. He craved a chocolate that was smooth, offering that irreplaceable melt-in-your-mouth texture. Thanks to Lindt, his dream became a reality using a machine called the conche. The conche was developed in 1879 and radically changed the texture, taste, and appearance of chocolate. Instead of grinding the chocolate using a metate (just like the Maya, Aztec, and Spanish), the conche continuously stirred the chocolate while using heat to create a creamy, melty, heavenly texture. Rumor has it that Lindt discovered this technique by accidentally leaving the conche running for a few days at a time. In my opinion, what started out as an accident actually turned in to one of the tastiest chocolate making discoveries.

This youtube video, “Production of Dark Chocolate Bean to Bar”, demonstrates the use a conche. As you can see, the chocolate is being stirred and particles are being polished in order to achieve that flawlessly smooth texture we experience when eating a Lindt truffle.

Another important improvement in the quality and texture of chocolate came about by the development the winnowing machine. As Kristy Leissle explains, “Prior to the Industrial Revolution, cocoa beans had to be broken and winnowed by hand” (Leissle 50). The process of winnowing by hand was extremely tedious and oftentimes excruciating, due to the fibrous husks that could easily cut the laborers’ hands and slip underneath their fingernails. Leissle goes on to explain the modern process as much more forgiving and user friendly. “Today, a machine usually cracks the beans, loosening or removing parts of the shell and breaking the seed into smaller pieces, which are then called nibs. A winnower sorts the nibs into piles of similar size, most often by vibrating them through screens with varying mesh” (Leissle 50). The winnowing process is crucial because when shells are not properly removed the taste and texture is compromised. The process is further explained and demonstrated in the video below.

This video from Craft Chocolate Tv explains/demonstrates modern day cracking and winnowing with the help of a winnowing machine.

One of the most impactful inventions in the chocolate industry was developed during the 18th century – The Hydraulic Press. Coenraad Johannes Van Houten’s hydraulic press completely transformed chocolate by pressing the chocolate liquor with immense force until two products appeared: cocoa butter and a solid cake. This process came about in 1828 when Van Houten decided that he wanted to create a powdered chocolate with a much lower fat content than what was already available. So, “For this, he eventually developed a very efficient hydraulic press; untreated chocolate ‘liquor’ –  the end result of the grinding process – contains about 53 percent cacao butter, but Van Houten’s machine managed to reduce this to 27-28 percent, leaving a ‘cake’ that could be pulverized into fine powder” (Coe & Coe 234). Applying this type of pressure with the hydraulic press made the production of chocolate much faster and more cost effective. Additionally, the Dutch chemist used alkaline salts to improve the flavor and prevent bitterness, which was well received by the masses.

Lastly, I would like to discuss the important concept of wedding of chocolate and sugar. This marriage of these two products played a huge part in the development and appeal of chocolate. Sugar was so important that “During the period 1750-1850 every English person, no matter how isolated or how poor, and without regard to age or sex, learned about sugar… A rarity in 1650, a luxury in 1750, sugar had been transformed into a virtual necessity by 1850” (Mintz 148). Manufacturer’s such as Cadbury and Fry began to flourish. As a result of utilizing sugar instead of other more expensive ingredients (such as vanilla), chocolate became available to the different classes due to the significant cost reduction. It also boosted chocolate’s appeal to children through advertisements using images of smiling kids like the boy featured in the picture below.

Fry’s chocolate advertisement is trying to demonstrate how their chocolate can please everyone — even an unhappy child previously throwing a tantrum. This advertisement appeals to both parents and children.

Because of the Industrial Revolution, chocolate went from being an expensive drink that appealed to an elite group of wealthy individuals, to a treat that men, women, and children could enjoy regardless of the social class they belonged to. As mentioned above, the conche, winnowing machine, hydraulic press, and the marriage of chocolate and sugar all played a role in making chocolate appealing and readily available to a much broader audience.

What Would you do for a Chocolate Bar? The Development of the Industrial Revolution and its effects on consumerism.

Today if someone wanted to have a chocolate bar, they would go to the supermarket and find at least ten different kinds of chocolates, in different shapes, flavors, and fillings. If you asked someone to name at least three chocolate companies they would be able to list at least five off the top of their head. Thanks to the industrial revolution (1760- 1840) chocolate is one of them most popular treat available today. In the 17th century, chocolate became a fashionable drink through Europe and was a privilege of the rich until the invention of the steam engine which allowed not only mass production to be a possibility but also eliminated the socio-economic divide between classes due to chocolate’s availability. Throughout the industrial revolution chocolate went through several advancements including: the invention of the hydraulic press, dutching, inclusion of milk in chocolate, and conching.

In the book The True History of Chocolate, authors Sophie and Michael Coe write about the history of chocolate consumption before the industrial revolution “for at least 28 centuries, chocolate had been a drink of the elite and the very rich… the Industrial Revolution, which changed chocolate from a costly drink to a cheap food” (Coe & Coe 232 -233). Before chocolate could be made available for the masses a few advancements needed to take place starting with invention of the hydraulic press. In 1828, Dutch Chemist Coenraad Johannes Van Houten took out a patent on a process for the manufacture of a new kind of powdered chocolate with a very low fat content eventually creating the hydraulic press. “This allowed untreated chocolate “liquor”—the end result of the grinding process—which contains about 53 percent cacao butter, but Van Houten’s machine managed to reduce this to 27–28 percent, leaving a “cake” that could be pulverized into a fine powder” (Coe & Coe 260)  creating what today is known as cocoa. Van Houten treated this cocoa mix with alkaline salt (potassium or sodium carbonates) to mix better with water. This process became known as “Dutching” it improved the powder’s miscibility (not, as some believed, its solubility) in warm water, it made the chocolate darker in color and milder in flavor. Even today, many people prefer “Dutch” chocolate, thinking it to be stronger in taste, when it is only the difference in color that makes it seem so” (Coe & Coe 260). Van Houten’s discover lead to a large scale manufacture of cheap chocolate in both powdered and solid form for everyone regardless of their social class or economic status.

Twenty years after Van Houten’s discovery, Francis Fry of Fry Enterprises figured out how to mix a blend of cocoa powder and sugar with melted cacao butter and cast it into a mold. Thus creating the first ever edible chocolate bar.

Due to the demand for chocolate bars, the price of cacao butter increased, once again creating a class barrier for chocolate, by providing chocolate bars for the elite. However, this price increase of chocolate bars and cacao butter, decrease the price of cocoa powder making it available to the masses. With the emergence of chocolate companies in the United States chocolate bars soon became available for the masses. In the United States of America, the production of chocolate proceeded at a faster pace than anywhere else in the world.

One of the most important evolutions of chocolate consumption includes the use of milk. the addition of milk to chocolate bars is credited to two people the first is Henri Nestlé, a swiss chemist and Daniel Peter, a chocolate manufacturer. In 1867, Nestlé discovered a process to make powdered milk by evaporation; when mixed with water, this could be fed to infants and small children (Coe & Coe 268). In 1879, Peter used nestlé’s powder in the fabrication of a new kind of chocolate, thus the first milk chocolate bar was created. “The process was simple: they dried out the moisture in the mix and replaced it with cacao butter, so that it could be poured into a mold” (Coe & Coe 268). Without this the discovery of  Hershey Chocolate Kisses or famous Chocolate bars would not exist today.

One of the last advancements made during the industrial revolution was the process of conching created by Rudolphe Lindt in 1879, which improved the quality of chocolate confectionary. A very meticulous process, “The traditional conche is formed by a flat, granite bed with curved ends, upon which heavy granite rollers attached to robust steel arms move backwards and forwards; the rollers slap against the curved ends, causing the chocolate liquor to splash back over the rollers into the main body of the mechanism. Since the action of the process causes friction and therefore heat to build up in the chocolate dough or paste, the preliminary roasting of the cacao beans may sometimes be omitted. After 72 or more hours of such rock-and-roll treatment, the chocolate mass reaches the desired flavor, as well as attaining a high degree of smoothness, due to a reduction in the size of particles. ”(Coe & Coe 268 ). This advancement allowed chocolatiers to make smoother chocolate bars, tasting almost like fondant, getting rid of the coarse and gritty texture it used to have, conching then became a common practice among the business.

The process of how Chocolate is manufactured and stored.

In The Bitter and Sweet of Chocolate in Europe Carla Martin and Kathryn Sampeck explore the role of race, gender, and class inequality attributed with chocolate production and consumption. While analyzing the social inequality and popularization of chocolate Martin and Sampeck write “ With the industrialization of chocolate, it was no longer a commodity for the the elite, expensive or consumed primarily as a drink but rather an inexpensive cocoa powder to be drunk or low-cacao-content chocolate bar to be consumed as a food by elite and non-elite alike” ( 49).  Chocolate became a treat that anyone can purchase and enjoy, well known companies like Lindt, Nestlé, Cadbury, Hershey’s, and Mars, attempted to produce a product that would taste the same every time thereby commercialize a product that had gone through enormous changes since the pre-columbian mesoamerica days.

While seen in the past a commodity to establish social identity in Kirsty Leissle’s book Cocoa she writes that today modern American companies including Cadbury and Hershey have contributed to the pre-existing social identity of chocolate. “ The companies most successful at crafting this social identity, including Cadbury and Hershey, have helped steer consumer desire for chocolate in certain directions – as an affordable luxury, holiday accompaniment, and surrogate for romantic love” (Leissle, 9). This remains true today, often during Valentine’s day Chocolate hearts, boxes shaped like hearts containing chocolate or even chocolate cake at restaurants on this holiday connect the idea of love to chocolate. The effects of the industrial revolution remains a strong component of consumer consumption of chocolate today, due to the advancements of the past it has never been easier to produce chocolate or purchase. Today people can enter almost any store and find a chocolate bar and that should be celebrated!

Cheap Sugar and Expensive Cacao: the democratization of the “food of the gods.”

Chocolate means many things to many people, invoking feelings of romance, decadence, comfort, celebration, and memories of childhood. And despite its ubiquity across most of the globe, chocolate has maintained an aura of lavishness, mystery, and prestige. Once a food item strictly for the elites, chocolate has kept its image as a luxury item even though it has been cheaply available for over a century. How and why did chocolate go from an exclusive luxury item for the privileged to a staple everyday treat for the masses? The history of chocolate, or cacao, the treated fruit-seeds from which chocolate is produced, and how it became commonplace is inseparable from the history of colonialism, the trans-Atlantic slave trade, and the industrial revolution. And the same is true of the history of sugar. Ultimately it was the evolution and combining of these two once-exclusive products that changed chocolate from an expensive, rare commodity for a small elite class to an affordable, mass-producible snack for the everyday citizen of the industrialised world.

Chocolate finds its origin in the cacao tree, or theobroma cacao, literally “food of the gods, cacao,” as it was named by Swedish naturalist Carolus Linnaeus.1 However, the word cacao had been used, as had the fruits and the seeds within, since long before Linnaeus encountered the species. Traces of cacao have been discovered on pottery dating as far back as 3,300 B.C. in Zamora Chinchipe, Ecuador,2 almost five thousand years before contact between Europe and Mesoamerica began. When Europeans first encountered cacao at the beginning of the sixteenth century, cacao was used as currency and consumed as a beverage by the ruling class of the Aztec empire. The drinking chocolate travelled first to the royal courts of Spain and then spread to the other major powers in Europe including, Italy, France, and England.  Drinking chocolate prevailed until the middle of the nineteenth century when solid chocolate was first produced for widespread sale.


Sugar has been known in Europe since long before cacao. Cultivated into its crystallized form in India as far back as 500 A.D.,3 and spread through the Arabic conquests of the eighth century, it was and remained “a luxury, a medicine, and a spice”4 until the seventeenth century. With the discovery and conquering of the West Indies, Europeans colonialists began to cultivate and mass-produce the luxury items – cacao, tobacco, coffee, rum, tea, and sugar – that would dramatically change the economies of the world forever.

By the nineteenth century sugar had a become a necessity of British daily life. And it was during this century that Dutch chemist Coenraad Johannes Van Houten invented a machine that would lead to the ability to produce chocolate in its solid form. Van Houten’s hydraulic press separated the fat, cacao butter, from the cacao beans, leaving behind a powder we call cocoa.5 The British Fry family, who had been producing and selling drinking chocolate since the eighteenth century, discovered that by remixing this cocoa with the butter and adding sugar, a liquid that would harden could be made, and the first real chocolate bar was born.6


It should be stated that none of the major producers of solid chocolate who would come to dominate the market were the first to think to sweeten cacao for consumption. Adding honey to sweeten drinking chocolate had been commonplace in Mesoamerica before the arrival of the Spanish, and drinking chocolate recipes enjoyed by the aristocracy in Europe pervasively contained sugar. The change that took place that would significantly spread the consumption of chocolate was the pronounced increased, first, in the consumption of sugar. According to Sidney W. Mintz’s estimates, between 1800 and 1890 world production shot from approximately two-hundred and forty-five thousand tonnes of sugar to over six million, and he writes, “there is no doubt that the sucrose consumption of the poorer classes in the United Kingdom came to exceed that of the wealthier classes after 1850.”7 This transformative period in sugar production and consumption paired with Van Houten’s machine, which meant for easier and cheaper production of higher quality cacao powder and butter, set the stage for the mass-production and consumption of chocolate.


The public’s insatiable appetite for sugar has meant that chocolate production can be much cheaper, as the most expensive ingredient, cacao, can be used in less quantity. A good example of this is the enormously successful Hershey’s kiss that is just eleven percent cocoa and over fifty percent sugar.8 And the mass-production ideology that came with the industrial revolution led to astonishing manufacturing achievements. A good example of this is the lettering machine at the M&M factory that is able to print the M’s on M&M’s at, “200,000 M&M’s a minute, or 100 million M&M’s every eight hours:”9 needless to say, a far cry from the time-consuming procedure to make the drinking chocolate that was enjoyed by Mayans, Aztecs, and European “nobility” for the centuries and millennia prior. That milk chocolate can be legally called as such with just 10% cacao content has meant a form of chocolate can be made, and therefore bought and eaten, cheaply and regularly across class lines. So while there is debate as to the health effects of cheap chocolate and ethical concerns of cheaply sourced cacao, the “food of the gods” is now available to all mortals. And thank god for that.

Two Sides Of The Chocolate Coin

While American and European consumers associate chocolate with romance, desserts, and luxury, the disparity between end product consumer and cacao producer is significant. One perspective is that northern consumers provide self-agency and opportunity through a free market economic exchange in an environment that provides few opportunities. While western Africa currently provides 75% of the world’s cacao (Coe &Coe, 2013) the African cacao grower has to rely solely on northern purchasers as they lack the economic resources to purchase, manufacture, or market their product. With labor as their only agency, the African cacao grower is in a disadvantaged position in the food production paradigm despite their high product yield. Corporate complicity in unethical labor, slave legacy that has left southern producers turning to raw materials for economic survival, and consumer apathy created by distance from the food supply chain have culminated in producing very opposing experiences for the cacao supplier and the chocolate consumer.

Success in Cacao

With the steady increase of cacao prices, the cacao-growing region of western Africa has seen steady socioeconomic growth in the industry for decades. According to “CNN Freedom Project,” an organization focused on labor practices worldwide, in 2008-2009 western Africa supplied more than 75% of the world’s chocolate, while Europeans and North Americans were consuming a roughly equal amount (2012). In their book Cocoa in Ghana: Shaping the Success of An Economy, Shashi Kolavalli, and Marcella Vigneri observe the steady increase of cacao prices have allowed for significant improvement via more investment in production yields through transport and infrastructure. (2012). Kolavalli and Vigneri further observe that so lucrative is the cacao production in Ghana  that positive socioeconomic influences of the crop, and improvement in western Africa’s poverty, have been significant by stating,

“economic growth has been solid, averaging more than 5 percent since 2001 and reaching 6 percent in 2005–06. Coupled with the effects of greater access to education, health services, and land ownership (World Bank 2008), this rate of growth has contributed to the near halving of the national poverty rate since the beginning of the 1990s, from 51.7 percent in 1991/92 to 28.5 percent in 2005/06” (p. 205).

For cacao growing countries in Africa, maintaining this resource is critical to prevent sliding backward economically in an already impoverished environment.

Who is Eating All the Chocolate?

According to CNN’s freedom project, northern countries are driving the demand for chocolate. In this breakdown for 2008-09, Europeans and North Americans were responsible for eating an equal amount of western Africa’s entire production, which is 75% annually of the world supply. In simple terms, if you live in the northern hemisphere there is a good chance you are consuming on average between 9 to 24 lbs. of chocolate per year. (Satioquia-Tan, J. 2015)

The Swiss eat 24 lbs. of chocolate per person, per year. That’s roughly equivalent to eating half of a Hershey bar every day for one year (Maxim75, 2016)

World consumption of cocoa: 2008/09
Europe – 49.32%
North America – 24.22% (United States only – 20.19%)
Asia and Oceania – 14.49%
South America – 8.68%
Africa – 3.28%

The demand from northern consumers continues to increase steadily. In his paper, Cocoa production in West Africa, a review and analysis of recent developments, Marius Wessel projects necessary agricultural growth for western Africa to maintain its current supply when he states, “The International Cocoa Organization (ICCO) forecasts a 10 percent increase in the world cocoa production and a 25 percent increase of the cocoa price in the next decade. … If West Africa wishes to maintain its present world market share a 10 percent increase in production is needed in the next decade” (Wessel, M., 2015). This is significant in that considerable investment will be required to meet the growing demand, which in turn will offer more employment from land developing to harvesting; boosting the economy even further. The staggering contrast of chocolate consumption between northern consumers and southern producers however, in relation to race and geography is no accident.

A History of Disconnection

After the chocolate drink of Mesoamericans made it to Europe via Spanish colonists in the 16th century, popularity of the drink in Europe began to rise. When Spanish colonists exhausted the Mesoamerican population as a resource for labor, they turned to the middle passage across the Atlantic to Africa for labor to meet the demand (Coe & Coe, 2013). On a continent that functioned tribally with no formal governments, it was quite easy to enslave people into labor for the remainder of their life, which on average due to hard labor and dismal living conditions was about 7 to 8 years after enslavement (Coe & Coe, 2013). This of course, required massive quantities of slaves, which Africa had in abundance. In his book Sweetness and Power Sidney Mintz observes that by the 18th century, the European lower proletariat was adopting the culinary habits of the aristocracy as a way of establishing equality for people in lower social stations (p.181, 1986). The biggest promoter of chocolate consumption for the masses According to Coe & Coe in their book A True History of Chocolate was the industrial revolution when they state,

The Menier Chocolate factory in Paris, France. Mechanized in 1830, and shortly after became France’s largest chocolate supplier. (Expressing Yourself, 2009)

“The Industrial Revolution, which changed chocolate from a costly drink to cheap food, [was] the driving force in this metamorphosis” (Coe & Coe, p. 232, 2013).

Before the industrial revolution the use of people from southern countries as a commodity for labor separated them from society and cultural habits of northern countries. Even had they wished to adopt the habits of their masters, there was no means or opportunity as a consumer base. Having never been ‘folded in” to European culture, they were completely disenfranchised as a chocolate consumer base. The exclusion of southern laborers and slaves from society as citizens, also found them ignored by the industrial revolution; leaving them to lag behind economically and industrially, unable to participate as consumers of chocolate.

State of Labor Today

After northern consumers developed a social conscience for disenfranchised populations and impoverished nations, one might be tempted to think everything has changed, but it has not. Still lagging from being on the outside of the industrial revolution, Cacao farming practices have changed little in the last hundred years. In villages of working adults there is a complete disconnect to their labor once it leaves the village. In her book Bitter Chocolate, Carol Off  tells of a village where all but the chief were ignorant of where the cacao went, none knew how it was used, and only one had ever tasted chocolate. Micheal and Sophie Coe argue that it is not only adults and families working, but that millions of children are trafficked and forced into slavery from neighboring countries (Coe & Coe, 2013). Off supports this claim by observing that slavery is alive and well  particularly in the Ivory Coast where child slavery is so common, it is a sub-industry of cacao with its own economy, as farmers finance networks to traffic children for forced labor who then suffer from starvation, disease and physical abuse while working on cacao farms (Off, C. 2006). While numbers of child slavery are at times sketchy and often disputed, no one denies it exists (Off, C. 2006).

Consumers Grow Distant

While slaves grow cacao, consumers grow distant. Though southern laborers have not advanced industrially, this is not the case for northern consumers. The industrialization of food completely changed northern food culture. Through mechanization, transport, and refrigeration, the distance between consumer and food source has grown. Mechanization produced food en mass cheaply, allowing access to goods that were more accommodating to lower budgets, while transport and refrigeration allowed food to travel further than it had before. (Counihan & Van Esterik, 2013) The biggest game changer in food culture was the mechanization of canning and preservation. With better preservation, food sources began to change, ingredients began change, and soon we had processed and prepackaged food embraced by women everywhere for freeing their time and labor (Counihan & Van Esterik, 81-82, 2013). After two or three generations of eating processed food transported from faraway places, with lists of ingredients that are rarely inspected, consumers today know very little about their food, or even what it contains. They are not unlike their southern counterparts in this way who do not know where cacao goes, or what its use is after it leaves the village.


Distance Creates Apathy

happy. As modern chocolate consumers in the north are far more concerned with inclusiveness, fair treatment, and food activism than previous generations, the power of the purchase is seemingly an easy solution to the poor working conditions and poverty that are still prevalent in the cacao industry despite its economic growth. Far removed from the supply chain, unaware consumers continue to purchase due to lack of transparency in food product, and manufacturers remain complicit in the absence of financial threat. Manufacturers however also have limited power. Even with strict purchasing policies, and government regulation it is still difficult to know if a supplier is using slaves without constant physical inspections (Martin, C. 2017), and blame shifts all along the supply chain making it easy for manufacturers to be complicit, and consumers to remain uninformed.  Lack of transparency in food sourcing, blame shifting in the industry, and distance from food sources, culminate to create a culture of apathetic food consumers.

How It All Comes Together

The dichotomy between cacao consumer and producer today began with early Europeans and European colonists who failed to view southern peoples as sovereign and instead as a voiceless labor resource. Excluded from global interaction, Southern populations failed to participate in cultural trends, shifts, and innovations that were transforming society and industry elsewhere. Non-participation in the industrial revolution left southern continents behind in what would become a global economy with no agency for economic competition; turning to natural resources and labor for economic survival in a state somewhere between hunting and gathering and industry with little opportunity for growth. While mechanization followed by technology has created decadence in northern populations as compared to southern countries, northern consumers are today ignorant of their food supply chain because of these advancements, and unaware of the poverty and labor practices of those supplying it. Lack of transparency in food products add to this distance, and northern Chocolate manufactures as well as governments are complicit in unethical labor practices, shifting blame along the food supply chain leaving those who are aware unsure of who to even hold accountable (Martin, C. 2017). While northern consumers today have more of a social conscience than their ancestors, the opposing lifestyles of the chocolate consumer and the cacao laborer have failed to come closer together over the last several hundred years due to a legacy of “othering,” and complicit corporate interests protecting their revenue stream that has created an apathetic northern food culture.

Where We Go From Here

Consumer awareness is growing. Projects like Fair Trade, CNN Project Freedom, End Slavery Now, Slave Free Chocolate etc., have been working hard to inform the public. Many consumers now seek out fair trade products when available, and appear willing to pay more for ethical practices. In their paper, Consumer Demand for the Fair Trade Label: Evidence from a Multi-Store Field Experiment ,  Hainmueller, Hiscox, & Seguiera state,

“Total sales of Fair Trade goods in the United States in 2011 amounted to roughly $1.4 billion (FLO 2012) … But the average annual rate of growth in U.S. sales of Fair Trade certified goods was close to 40% between 1999 and 2008” (2014).

Fair Trade is not without its problems, as certification can be costly and marginalizes the poorest producers, but it is a start, and one of few ways to access transparency of the food supply chain in a consumer market that provides no source-to-store product information. Legislators are also working to intervene in child slavery practices. Senator Tom Harkin and Representative Eliot Engen introduced a protocol to reduce trafficking in the cacao industry, agreed to by manufacturers and legislators from Ghana and the Ivory Coast as stated by the ILO, “that aims to reduce the worst forms of child labor by 70 percent across the cocoa sectors of Ghana and Cote d’Ivoire by 2020” (ILO, 2017). Currently Fair Trade and other transparent and ethical alternatives have not achieved mainstream mass production, making it difficult for a consumer to use the power of the dollar against corporate complicity even when they choose to. Raising awareness and creating a demand for ethical products can aid in ending consumer apathy by closing the information gap, and denting corporate revenue streams that, with some work, will promote less disparity between southern suppliers and northern purchasers.

Churning into the “Chocolate Age:” How Industrial Age Technologies Created a New Chocolate Era

You may be surprised to find out that the chocolate that we know today is a relatively new, tasty discovery- one that came about from the Industrial Age.

When the Industrial Revolution took place, the world revolutionized with it, and industries of all kinds were forever altered. The chocolate industry, still in the Mayan age, sprouted into a new field and its effects can still be traced today. The technology in the Industrial Revolution provided the tools to advance the field of chocolate, which allowed for mass consumption and commercialization, giving way to the “Chocolate Age.”

Chocolate’s “God-Like” Beginnings

Cacao was considered the “food of the gods,” and was treated as such: before the Industrial Age, chocolate was made the traditional way that the Mayans made it with a long, drawn-out process of cracking shells and traditional grinding to create a bitter chocolate drink (unlike the chocolate of today) (Szogyi, 1997).

would grind cacao (Smithsonian)

This treat was considered to be a drink that was both a commodity and spiritual experience; although it was available to the masses, the wealthy certainly had more access to the treat because they could afford it. Cacao was taken as such a serious product that the Mayans used its seeds as currency; further, it was used to promote fertility and life, and cacao pods are found all over elite and ancient artifacts, temples, and palaces. Clearly, these uses and techniques demonstrate how luxurious chocolate was to them; these processes stayed this way even during the era of the Aztec empire and many centuries later (Horn, 2016 & Szogyi).

The Industrial Difference

This process of chocolate was so revered that it essentially did not change until the Industrial Age with a ground-breaking invention for grinding that used the newly-innovated steam and hydraulic process; in 1778, Doret, a Frenchman, invented a hydraulic machine that grinds cocoa beans into a paste (Beckett, Horn). Before then, the process of grinding was long and tedious and this machine allowed the process to become easier to create for the masses. Soon after, more inventions came along for grinding that further made consumption more popular. For instance, Dubuisson invented a steam chocolate grinder in France because it was even cheaper to replicate than Doret’s product, which allowed for an even higher level of mass consumption of chocolate. The Industrial Age created the environment to allow for this change – without steam and hydraulics, and the friendly and booming business atmosphere for support, Doret and Dubuisson would certainly not have been able to create these inventions. Where would be chocolate be today? One could reasonably predict that we could have eventually have had these technologies, but it is safe to assume that it would have taken the chocolate industry much longer to reach its glory.

The steam engine and hydraulic system are considered staples of this Industrial Age with new technologies across the boards for trains, factories, and buildings, but we can also appreciate how these technologies allowed for the advancement of chocolate technology. The value of chocolate significantly decreased because it was accessible to everyone; from here on, it was no longer an “elite” product or just a “food of the gods,” but, rather, a food for everyone. Thus, the Industrial Age that changed the world on so many fronts quickly churned into the “Chocolate Age” as well.

The idea of the mass consumption of chocolate from the Industrial Age can be traced along the later part of the history of chocolate. Quickly after the revelation with the cocoa beans came a new way to make chocolate an even more accessible product with commercialization – via “dutching” (Squiciarinni & Swinnen, 2016). In 1828, Van Houten, a Dutch chemist, invented a method to press cocoa by separating the cocoa butter by pressing it with alkali, making the matter soften up enough to produce cocoa powder, which was light and fluffy; unlike the current chocolate of that time, dutching made chocolate highly digestible, which would attract new consumers and open up a whole new market for chocolate – just like these technologies helped do so in other industries such as the construction field (i.e. making materials more affordable and attractive for building).

Additionally, cocoa powder was the secret ingredient needed for the chocolate industry and companies to seamlessly make solid chocolate bars and coat them as well as bring in new flavors such as white chocolate. From there, a second wave of the Chocolate Age had been set and was about to take place.


A Second Wave of the Age – Mass Commercialization and the Chocolate Bar

With the mass consumption of chocolate from these new Industrial technologies came mass commercialization. Quite simply, we can see that chocolate companies would not be what they are today without this commercial influence; specifically, the dutching process sparked a spread of commercialization across Europe, which allowed for the worldwide chocolate industry we have come to know and love. For example, Cadbury, one of the largest chocolate companies today, and Joseph Fry (founder of what is known as Mondolez International today) bought the dutching press; these two companies are credited to be the first companies to create and sell the chocolate bar. They also made the chocolate bar a highly accessible treat with aggressive advertising; this marketing scheme raked in millions of dollars for these companies (Beckett, Horn). It was the catalyst behind the beginning of giant factories built to keep up with this demand.

Thus, the chocolate bar became (and still is) a symbol for a quick, delicious treat for everyone and anyone.

Moreover, the dutching system then inspired the chocolate exportation business that brought chocolate on to an international stage – a few decades after the start of the chocolate bar, the Van Houten presses became powered by steam engines, and, just like with the Dubuisson’s steam engine, came with another Chocolate Revolution. The mass consumption and commercialization of chocolate began in European countries such as Germany and France, which eventually led its way to the United States (Beckett, Szogyi). These countries then started their own chocolate giants such as Hershey’s and Nestlé, which embody the same mass consumption and commercialization ideals that have advanced the history of chocolate along and allowed it to further churn.

Without the Industrial age, chocolate would just not be the same. It is literally unrecognizable from its Olmec and Mayan roots. From the Industrial Age, the Chocolate Age churned on and on – all starting with the advancements in steam and hydraulics.
