For my final multimedia essay, I chose the topic of visiting a retail shop such as CVS, and explaining what I can learn from this section. What I noticed when I walked from work to the Harvard Square CVS not too far from my walk home, was that the section wasn’t that large and most of the chocolates that were being presented were Ghirardelli. When viewing the section, I noticed the sign which said “Premium chocolates’ and as I viewed closer I noticed that the Ghirardelli chocolates came in different varieties. There were chocolates that were in different percentages of cocoa. They ranged from 78%, which is a weird percentage to 85 and 90%. The chocolates also were diverse because some of them that were being sold were white chocolate with coconut, while others were either dark chocolate or chocolate mixed with nuts such as almonds, hazelnut and cranberries. The prices were also another factor when I was observing this small section. Most of the chocolates that were on display had a 2 for 6 option while most of the chocolates were about $5. The section where the chocolates were displayed was next to the fridge area in CVS where most of the frozen foods are. It was also next to the snack aisle where there were tons of donuts, popcorn and other sweet foods. The other side of the premium chocolate section had chocolates that were all mostly Ghirardelli that had chocolates that were nearing $6 but there was a sale going on that made all of the chocolates “buy one get one 50% off”. I believe the chocolates were very inexpensive because the companies have to tend to their audience. Not everyone wants to buy expensive chocolate.
Here is a picture of the Premium Chocolates Section:
The History of Ghirardelli
Why is Ghirardelli such an important brand in chocolate history? Well first, Ghirardelli was first founded in 1852 in San Francisco, California. It is currently the third oldest chocolate company in the U.S. and was founded by the Italian Chocolatier Domenico Ghirardelli. The company has their business partner company, Lindt & Sprungli which is their parent company. Since the company’s start, they have been working on new techniques and different technologies to remain at the forefront of chocolate consumer brands. “The shop has experimented with a variety of products, including a line of alcoholic beverages until 1871, and a variety of goods like coffee, spices, and even mustard throughout the years. Innovation became tradition throughout the company – in 1867 a Ghirardelli employee discovered a flavor-enhancing technique that would eventually become widely used throughout the chocolate industry. Ghirardelli became one of the first American companies to tap into advertising strategies in order to gain popularity, and one of the first to include cacao content on labels to help discerning consumers select the perfect taste (Holcomb, Courtney. “A Brief History Of Ghirardelli Chocolate.” Culture Trip).”
I believe this company is trying to be the main consumer for chocolate because based on learning the classes lectures, about 200 years ago Americans only ate about 2 pounds of sugar a year. Studies from 1970 show that Americans ate even more sugar as the data increased and showed that Americans ate about 123 pounds a year. Today, the average amount Americans consume of sugar is now 152 pounds a year. In 2017, American consumers spent a whopping $22 billion on chocolate, averaging at around 12 pounds per person. America has been well known considering how much they love sweets and how commercials and marketing play a big role.
Chocolate History from Lectures
In 1879, Rudolph Linte, was the first to invent the conching process in Switzerland. This is major in chocolate history because conching helps with increasing viscosity in order to process the chocolate. “In the majority of chocolate manufacturing plants, the conche is preceded by a roll refiner or a hammer mill. These grind the chocolate mass to produce a crumbly paste or powder. One of the main aims of conching is to produce the optimum viscosity for the subsequent processing. The actual viscosity can be reduced by adding more fat, but as the price of the fat is frequently several times that of the other ingredients in the chocolate, this in turn increases the cost of the product. The aim, therefore, becomes one of obtaining the optimum viscosity at the lowest practical/legal fat content (Beckett, S. (2017). Conching).”
Chocolate Company’s Strengths
A lot of a chocolate company’s strength is definitely marketing and publicity There has been this stigma that anything sweet, and attractive to the tongue is good, and that’s what a lot of chocolate companies have marketed themselves to be. That’s why during certain events such as Easter, companies thrive during those times because they take advantage of the sweet equals good stigma because of the easter marketing standards for kids. Most kids for Easter always go easter egg hunting, and usually what’s in the eggs are chocolate or some sweet. Chocolate companies take advantage over holidays like Easter and Halloween because that helps with their revenue.
Ghirardelli has been so successful that they have their own square in San Francisco, California. In 1893, Domenico Ghirardelli purchased a whole block, so he can make the Ghirardelli headquarters. In the early 1960’s it was sold to a macaroni company and was letter repurchased in 1962. His mother, William M. Roth purchased the land so it wouldn’t be used to create a new apartment complex. “The Roths hired landscape architect Lawrence Halprin and the firm Wurster, Bernardi & Emmons to convert the square and its historic brick structures to an integrated restaurant and retail complex, the first major adaptive re-use project in the United States. It opened in 1964. In 1965, Benjamin Thompson and Associates Renovated the lower floor of the Clock Tower, keeping the existing architectural elements, for a Design Research store.The lower floors of the Clock Tower are now home to Ghirardelli Square’s main chocolate shop. In order to preserve Ghirardelli Square for future generations, the Pioneer Woolen Mills and D. Ghirardelli Company was listed on the National Register of Historic Places in 1982 (“Ghirardelli Square.” Wikipedia, Wikimedia Foundation).” This company is so well respected and well known, that a whole entire block was dedicated to the company’s main focus, chocolate.
Why is Dark Chocolate so special?
The french are known for eating dark chocolate as a treat, but why? Are there certain benefits towards eating dark chocolate or is it just well known for being such a good treat? During the chocolate production process, to increase the appeal of chocolate, most times the chocolate is processed even further which in turn makes the chocolate lose key ingredients that can be beneficial to our body. For example there is a type of processing of chocolate called Dutch processing and that makes the chocolate lighter. This sucks out all the key ingredients that make chocolate, chocolate. That’s why most companies add tons of sugar in their chocolate bars to make it more appealing to consumers. “And to make milk chocolate, candy makers really do add milk solids, which include saturated fats. According to FDA standards, American milk chocolate can contain as little as 10% cocoa, and the agency is debating a proposal to allow candy makers to substitute vegetable oil for cocoa butter. Bottom line: processing may make chocolate look lighter and taste sweeter, but it also removes healthy ingredients and adds harmful ones (‘Chocolate and your health: Guilty pleasure or terrific treat?).”
Statistics on Chocolate
After reading an article from Rodman media, I noticed that more than 70% of chocolate consumers are aware that dark chocolate is more healthier than white chocolate. “The latest research from Mintel revealed that for just more than half (51%) of all adult consumers, the favorite type of plain chocolate is milk chocolate, followed by 35% who favor dark chocolate and About 73% of all chocolate consumers are aware that dark chocolate is healthier than milk varieties. 8% who prefer white chocolate. In contrast, Mintel’s 2011 report found that 57% of consumers favored milk chocolate and 33% of consumers preferred dark chocolate. Some 46% of men age 55+ and 48% of women over age 55 favor dark chocolate, followed by 38% of men that prefer milk and 40% of women that also prefer milk. These numbers are indicative of the trend toward the increasing favor for dark chocolate. Indeed, 73% of all chocolate consumers are aware that dark chocolate is healthier (‘Dark Chocolate Gains Favor Thanks to Health Benefits’ (2013) Nutraceuticals).”
Chocolate companies such as Ghirardelli always make sure that they have different rudiments of cocoa flavor so that there is a variety of taste in each chocolate bar. Usually the more cocoa, the more expensive the chocolate is towards the consumer. I believe that sugar and other ingredients that make the chocolate taste more appealing, cheapen the chocolate itself. The more natural the chocolate is , the more untouched and less processed, the more bitter taste it has. That’s why dark chocolate is healthier for chocolate eaters than milk chocolate is. In one of the lecture slides from class, I witnessed a list of different odor active volatiles in cocoa mass. This shows what each odorant is and how their odour quality would be, the qualities range from a malty quality to a fruity one. There are a lot of factors incorporated with cocoa, and its key that all industrial companies follow the many rules in order to have a better consumer base.
Picture of the rudiments of cocoa flavor:
In conclusion, I believe that one of America’s oldest brands, takes pride in their industrialization of cocoa and how it should be manufactured. By investigating the chocolate section at my nearest CVS, I noticed the different brands in the regular chocolate section VS. the premium chocolate section . I realized the different percentages of cocoa in each chocolate bar and researched the effects of dark chocolate VS. white chocolate. I found it interesting how much Ghirardelli was displayed at the CVS and how there were many buy one get one 50% off deals. I dug deeper into the history of Ghirardelli along with the company’s strengths on consumers which showed me there’s a lot more to chocolate than just manufacturing it. More factors would include, marketing and knowing what your consumers like or don’t like. While researching this company I also learned a lot by viewing past lectures and how they related tremendously to the company and how they process their chocolates. Certain holidays mean a lot as well because in America, chocolate and sugar has been a known ingredient to use in basic cooking ingredients. And a lot of companies used that stigma to take advantage of the use of chocolate. I learned a lot based on the prominence of cocoa and how there is a lot to process before the chocolate is being sold in certain stores. The history of chocolate related to the history of Ghirardelli and other brands because of their processing system and how they plan on improving their company in various ways.

Molded by years of exposure to masterfully crafted marketing campaigns, average consumer knowledge of cacao [or cocoa] is limited to its function as an ingredient and source from which their beloved chocolate is derived. There is much more to the birth, rise, and spread of Theobroma cacao.
The following seeks to explain how a culturally significant crop among early civilizations dating back to 1500 BCE (Coe and Coe, 2013) transformed from a highly treasured ingredient and social currency cultivated within a fairly limited zone to a globally produced and traded commodity: a highly reformulated, mass-produced, and readily available confectionery product.
This journey traces cacao back to its genetic and cultural beginnings where it was religious and cultural fixture among early civilizations; how exploration and migration played into the geographical expansion of its cultivation and rise in popularity as a food; role in accelerating industrialization; and transformation from a social currency and treasured ingredient to a heavily traded commodity and mass manufactured consumer product.
Genetic and Cultural Beginnings
From births and burials, recipes and rituals, cacao’s cultural origins are linked to Mesoamerica (present day Mexico through Central America), where its social and religious significance among the Olmec dates back to 1500 to 400 BCE (Coe and Coe, 2013). The rise of Maya and Aztec civilizations gave way for cacao’s evolution utility and proliferation as a consumable.
Cacao’s Role in Society and Religion
Evidenced by archeologic discoveries, translated texts, and scientific testing, several vessels and writings have been unearthed, clarifying and validating cacao’s significance, religious ties, and early application as a currency.
Mayan and Aztec civilization associated cacao with the gods. As such, they were believed to enrich and afford protections during and after life, playing a central role in offerings and rituals (Coe and Coe, 2013).
Ceramic vessels similar to those pictured here which date back to 455 to 465 CE were found in burial tombs at Río Azul (Martin, 2019). Further testing confirmed positive traces of caffeine and theobromine—two of cacao’s alkaloid signatures (Martin, 2019).
Dating back to 455 to 465 CE, “funerary vessels” similar to those pictured here were discovered in tombs at Río Azul. As testing revealed traces of caffeine and theobromine, two of cacao’s signature alkaloids, this further supported evidence of cacao’s religious significance (Martin, 2019).
As a food or drink, cacao took many forms. Popular among the Maya and Aztec, “cacahuatl” was a frothy preparation often transferred from one vessel to another and served cold (Coe and Coe, 2013).
Exploration and Migration: Changes in Cultivation and Consumption
By definition, explorers were bound to make new discoveries and learn from their experience. Capturing the innocent confusion and eye-opening experience (only to be realized years later), the following briefly details just how one explorer mistakenly thought that cacao beans were almonds.”
Mistaken for Almonds: When recounting observations from his 1502 landing at Guanaja, one of many landmasses that make up the Bay Islands archipelago, Ferdinand Columbus, one of Christopher Columbus’ sons wrote about cherished “almonds” that traded hands similarly to how currency would pass between customers and merchants (Coe and Coe, 2013). It was not until years later after multiple interpretations and sources concluded that what he presumed to be almonds were in fact cacao beans.
As it came to be more widely known, not far from where Ferdidnad landed, throughout the Rio Ceniza Valley (present day coast of El Salvador), cacao was an increasingly popular form of currency being produced and traded in record volume—something . In time, this led to further learnings about the “Nahua counting system” and subsequent adoption of cacao as payment for “protection” by Spanish conquistadors.
Generally relegated to tropical climates falling 10-15 degrees north and south of equator, is was inevitable that cacao would make its way around the world. So as people moved, and culture spread, so too did the cacao, as a crop, currency, and curiosity, ultimately leading to its introduction to new geographies, and paving the way for new industries and traditions around the world (Martin, 2019).
New Formulations and Complementary Ingredients
As ingredients such as vanilla, chili, and many others traveled around the world, pairings and formulations rapidly evolved. Marking a major development and informing direction for the confectionery side as we know it today, sugar was introduced to Europe around 1100 CE and chocolate followed shortly thereafter in 1500 CE (Martin, 2019).
Cacao’s Role in Accelerating Industrialization and Expanding its Place in Society
While cacao consumption continued to be reserved for certain classes during its journey around the world, increasingly sophisticated processing methods streamlined productions, regulation eventually brought its price down, and despite medical and religious challenges to its place in society, cacao products were increasingly available to a grander population.
By the 1600 and 1700s, advances in processing continued to align with rising and more diverse consumption habits. Of course, by this time, the separation between “producing” and “processing” countries (read: colonies vs. industrialized nations) was increasingly clear.
So while cultivation and production spread across Central and South America, Southeast Asia, and Africa to meet demand, industry began to take shape on the consumer side as well with the emergence of social gathering halls or “Chocolate Houses” in Britain, France, Spain, the United States, and other “industrialized” nations who had transitioned to managing the cacao’s trade as a commodity and processing for various food and beverage applications. It was not until Rudolphe Lindt’s invention of the conche in 1879, an advancement that bolstered flavor and feel (among other things), and set the stage for quality, processing, and mass production to take off (Coe and Coe, 2013).
Illustrated above, the matete, grinder, and conche are examples of what cacao processing tools were used by early civilizations (and are still used in the same or similar forms today) and evolved or industrialized processing equipment employed today (Martin, 2019).
From early civilizations to present day, cacao’s role in society, cultural significance, availability and consumption have evolved tremendously. However, its mystique and association as something special are still true to this day—just as they were in different and more elaborate forms among early civilizations. Perhaps this condensed history will give pause and reason for the average consumer to think beyond commercialization of cacao, cocoa, or chocolate, and value and validate its history and claims made by brands to improve global understanding, perception, and consumer habits.

What are some descriptors that pop into your head when you think about chocolate? Smooth? Creamy? Velvety? Those are some of the feelings Dove wants you to imagine when you are viewing their ads like the one above which show gleaming liquid chocolate on and even comparing their chocolate to silk throughout. Though these are some of the modern connotations of chocolate, its origins were anything but. As technologies improved, the goal of chocolate makers moved towards smoother and smoother chocolate, that is, until technologies allowed for chocolate to become “too smooth,” after which consistency became more of a conscious choice by chocolate makers.
Evidence of cacao consumption dates back to as early as 1900 BC according to tests on pre-Olmec vessels found at archeological sites in Mexico and Central America. The word cacao is sometimes thought to come from the Olmec word “kakawa.” The Olmecs, whose civilization prospered from approximately 1500 BC to 400 BC, likely used cacao for religious and medicinal purposes. They were also possible ancestors of the Mayans who are thoroughly documented—primarily from the Dresden Codex—as having used cacao in many aspects of their lives. When the Maya consumed cacao, it was often in the form of a frothy beverage, often mixed with maize and spices. One technique involved grinding the cacao nibs with a metate, a curved volcanic stone slab. The individual grinding the nibs uses a stone roller with a curvature almost matching that of the metate. Then, while the nibs are being ground, small amounts of water are tossed in, creating a sort of cacao paste. When this is mixed with other ingredients in water, granules are still very much present and noticeable. There will not be any whole nibs, but particles will still be distinguishable. In the video below, at approximately the 2 minute mark, we can see a woman, affectionately referred to as Señora Ruiz, grinding roasted beans on a metate. Usually, the beans would be deshelled, or winnowed, which leaves only the nibs, but this is not necessarily a mandatory step. We can see that even after she grinds it into a “fine” powder, the cacao paste is still visibly granular. In addition, in the video, Señora Ruiz adds sugar—among other ingredients—to the cacao paste. Sugar was not introduced in Mesoamerica until the Europeans brought it over during colonization, thus the recipe that Señora Ruiz is concocting is, in fact, not a true ancient Mesoamerican recipe.
and other instruments like it were among the only ways to grind cacao until around
the early 1800s as the industrial revolution ushered in new mechanized methods
for refining chocolate past what was possibly by hand. The first major
breakthrough in this was when Coenraad Johannes van Houten patented the
hydraulic press in 1828. The hydraulic press allowed cocoa powder to be separated
from the cocoa butter, “a peculiar mild fat…to the amount of 43 per cent
according to Bousingault, and 53 per cent according to Lampadius” (Scientific
American 3). Not only could this process separate the two which allowed the
cocoa powder to become finer, the cocoa butter could then be added later in
different quantities which alters consistency and texture. The same Scientific American article that described
the proportion of cocoa butter per bean also outlines another new technology of
the time, a granite cacao milling machine, “a machine consisting of an annular
trough of granite, in which two speroidal granite millstones are turned by
machinery” (Scientific American 3). This is yet another step in the road to
finer, smoother chocolate. The technology is not immensely complicated. It is
still, at its core, a stone that is grinding cacao, just like the metate, yet
this machine can do the process more intensely, more efficiently, and with more
brought the concept of conching into the world of chocolate thanks to Rudolphe
Lindt (yes, the same Lindt as Lindt Chocolate). Conching involves the cocoa
butter being re-added and the chocolate liquor being continuously turned in a
large vat, evenly distributing the cocoa butter and any other ingredients that
are added at this stage. According to F. H. Banfield, Director of Research at
the British Food Manufacturing Industries, conching along with controlled
grinding “can standardize the smooth-eating qualities of his product” (Banfield
299). It is interesting to note that in this article, he mentions chocolate as
a couverture, in which the consistency matters a great deal as flow rate and viscosity
are vital factors due to the chocolate not flowing evenly if it is too thick and
draining off if it is too thin. Thus, consistency is not only important for the
mouthfeel it gives a consumer eating it straight, but also with its performance
around other food items.
Lastly, an invention that debuted in 1912 but is still widely used to this day is the three-roll mill (or five-roll mill depending on the preferred end consistency). During this process, the chocolate liquor is run through a number of tightly spaced rollers that squeeze the liquor through, reducing its particle size. The more times this process is run, the finer the texture of the chocolate gets. Most chocolate makers today aim for 18-20 microns for their particle size. Particle size is a delicate balance. A particle size too large and the consumer can feel individual granules within the chocolate—which is not necessarily a bad thing and at times done intentionally, especially by more artisanal chocolate makers. A particle size too small and the consistency of the chocolate comes off as almost gooey. The video below shows the chocolate process as a whole but does a good job of describing the rolling process and its significance with consistency. Not only does it get the particles to a desired size, it shapes them into almost “pearl-like” spheres so that they roll, instead of sticking to the palette.
Mesopotamia, the most advanced form of chocolate grinding came in the form of
the metate resulting in cacao products and beverages with rough and gritty
cacao particles. The Industrial Revolution was the impetus for many chocolate
related inventions, the first of which being van Houton’s hydraulic press which
allowed for the separation of cocoa butter from cocoa powder. The conching
process, invented by Rudolph Lindt, allowed for a smoother chocolate by
re-adding cocoa butter and thoroughly mixing the chocolate liquor. The final game
changer with regards to consistency was the three-roll mill. It was this
invention that allowed for the chocolate liquor to become not only fine enough where
individual particles are indistinguishable by the tongue, but too fine to where
the chocolate feels gooey. Whereas originally, chocolate consistency was a
factor of the present technology, after many inventions and adaptations of technologies,
consistency has become a conscious choice.

A few months back my aunt Bazat Saifiyyah made a chocolate sauce that everyone in my family went completely crazy over. We would eat it at breakfast, lunch, and dinner. With many different foods such as ice-cream, strawberries when they were in season, spread over toast or just eaten plain.
For my blog post I want to explore within the context of my aunt’s recipe, the ingredients that go into it, where does the chocolate come from, the historical backing and also the perception of chocolate and its health benefits.
The ingredients that go into the chocolate sauce are butter, dark chocolate compound, Hershey’s natural unsweetened cocoa, Hershey’s caramel syrup, icing sugar, milk and fresh cream.
The chocolate sauce is made by melting butter over a low heat flame, then add the dark chocolate compound broken up into many pieces. Then after this has melted the milk and fresh cream are added and then whisked until fully mixed. Then after this, the Hershey’s natural unsweetened cocoa powder is added with the icing sugar. After this, the caramel syrup is added. Then the whole mixture is to be whisked over a low flame for two minutes, then it is ready to be eaten.
This is a short video that I have taken during the making of the chocolate sauce.
What is the history behind the recipe?
Cacao first came to be cultivated agriculturally by the Olmecs in the lowlands of the Mexican Gulf Coast ( C ) It was picked up by the Mayans and then from them the Aztecs. In this time the way that they processed the cacao bean was very different then how it is processed today. The cacao pod would be harvested and then its beans would be dried, roasted, shelled and then ground on a metate to make a paste, this paste could have other flavoring additions to it depending on the culture that it was made in. This paste was then made into balls from which a hot foamy chocolate drink was made, this seems to have been the primary way in which the Mesoamericans consumed their cacao. However, there are mentions of it being used in other food items. ( C )
This is a video that demonstrates the Mesoamerican chocolate making practices.
This cacao consumption was picked up by the Spanish during their colonization period. It became an extremely important part of their culture and practices. Then it was picked up by the European colonizers and it became joined with sugar that was also being produced in the colonies. Then came the inventions that changed how chocolate was produced such as conching by Rudolph Lindt in Switzerland, this made the chocolate smooth by breaking down the large particles in a machine. ( P ) Also, the addition of dairy products like milk and cream to chocolate changed drastically how chocolate was enjoyed by many people.
Where does the cacao come from?
The two chocolate products that go into making this compound are Hershey’s natural unsweetened cocoa and Mordes dark compound chocolate ( CD D16 ). Both these ingredients are processed differently to reach the state that they are in.
Hershey’s natural unsweetened cocoa-
The processing of cacao to reach cocoa powder was invented by Coenerad Van Houten in the Netherlands. He developed a technique which processed cacao beans in such a way that they separated into two compounds, cacao butter, and a solid cake. ( P ) The cacao butter was the more prized of the two compounds and often it was sold by companies and not used with the solids of the beans that it came from. The solid cocoa cake that was made was then ground up into a fine powder and it is used in chocolate drinks and baking. Another process that also goes behind the cocoa powder made today is the dutch processing technique which is a treatment done by adding alkaline salts to neutralize the bitter taste and also to have a darker colored chocolate. ( P )
There is no mention of the product about where the cacao that goes into this process comes from. This makes the cacao completely anonymous.
This anonymity of chocolate shows a shift in the attitudes of people towards cacao beans and their sourcing. In the past centuries, before the manufacturing of chocolate became so connected to the industrialized process, the sourcing of the cacao bean was of utmost importance. The criollo pods were counted as the best type of cacao, it has the sweetest flavor and the richest taste ( P), the finding of this pod is extremely rare nowadays and many expert chocolatiers try with great difficulty to get a hold of this criollo pod to make their chocolate. This pod was mainly used by the Olmecs, Mayans, Aztecs and then it was transported to Hispanic plantations such as Venezuela during their period of colonization. ( P ) The most common type of cacao in use today is the forastero variety, this is purple and of a darker color then the criollo variety, it is also extremely bitter however the multiple industrial processes that cacao beans go through these days balance out the bitterness. Then there is also the Trinitario variety, this is a cross breed between the criollo and forastero, it was developed in Trinidad, this is the most resilient variety and it has a more pleasant taste than the foraestro. ( P )
The other factor that matters a lot in the sourcing of cacao is where is it grown, this contains the Terrior of the landscape and also carries a lot of history and chocolate traditions and culture with it. Chocolate has a dark history intertwined with the slave trade and abuse of peoples in plantations. In the modern day, the roots of colonization, the booming cacao trade, and European chocolate culture has led to established cacao farming in many parts of the world that were colonized such as Brazil, Cote d’Ivoire, Cameroon, Ecuador and West Africa. Today West Africa produces 75% of the worlds cacao and most of this cacao is exported for production abroad, only 4% of the worlds chocolate is consumed by its people. West Africa collectively produces 3 million metric tonnes of cacao in a year( L 8)
There is a lot that goes into the cacao bean and if it is made so anonymous its history is wiped away and its variety and subtleties are emitted out of the chocolate making process as nobody knows where it originates from.
Mordes dark compound chocolate ( CD D16 )
This chocolate is also another example of the anonymity of the cacao bean today. The ingredients that go into making this bar are as follows, Sugar, Edible Vegetable fats, Cocoa Solids and Emulsifiers ( 492, 322 ) CONTAINS ADDED NATURAL (VANILLA) FLAVOURING SUBSTANCES, Hydrogenated Vegetable Fat Used- Contains Trans Fats.
This bar does not have a cacao percentage in it however it has cocoa solids, so it does not have cacao butter in it.
This is a video that demonstrates how chocolate bars are made today.
A look into Hershey’s
Hershey’s was founded in 1903 by Milton S. Hershey, it came to be known as Americans most iconic chocolate. It had a great influence on American business and taste. ( L 11 )
The two struggles that this company faced and managed to overcome were, one, the struggle to develop milk chocolate, so they made their own dairy farms and sourced their milk from there. Two, the struggle to control the sugar supply chain. Sugar used to come from Cuba and during the period of 1916-46 there was a highly volatile situation and this affected the sugar supply chain. To face this problem Hershey brought land in Cuba where he established his own sugar plantations, for the transportation of this sugar he also built some connecting railways. ( L 12 )
This is a video that demonstrates the history and founding of Hershey’s chocolates.
The potential health risks in consuming chocolate are environmental factors of polluted soil and water, problems in other ingredients such as milk, sugar, soy lecithin, inclusions, manufacturing issues, allergy or sensitivity to certain ingredients mixed with the cacao or to the caffeine, and a very high sugar and saturated fat content and a very high calorie content. ( L 12 )
There has also been a lot of contemporary research on the health benefits of chocolate. These are Antioxidant, Cardioprotective, Psychoactive, Anti-inflammatory, Anti-allergy and Anti-tumoral properties ( L 12 )
After knowing some of the history behind chocolate and everything that has gone into making it, one can eat the chocolate sauce with more understanding of what actually goes on in the making of it.

The sourcing and production of chocolate had a direct effect on its place in the social hierarchy in different societies and cultures across time. It is possible to see this by going in depth into three chronological time periods in different places in the world where the allure of cacao had spread. By an early exploration of Mayan chocolate production to Venezuelan plantations ending at the discovery of the Cocoa press in the Netherlands.
Mayan Chocolate Making
Mayans revered chocolate, it played an essential role in their stories of origin and cosmology. It was used in burial rites and great ceremonies. Cacao was grown agriculturally by the Mayans 1.
One of the only direct evidence discovered about how Mayans made their chocolate is found in this vessel on the right-hand side which shows a lady pouring chocolate drink from a height into another cup. This was to create the foam that was extremely prized in the Mayan culture; it was thought to be the breath of the Gods.
This Maya Princeton Vase is evidence for the heavy usage and importance of cacao in the Mayan culture. It has engraved hieroglyphics for the word cacao coupled with cosmological depictions.
The Maya had many ways of using Cacao to make food.
Chacau haa – This is hot chocolate drink.
Tzune – This is a mix of cacao, maize and sapote seeds.
Saca– A gruel made from cooked maize, water, and cacao.
The flavoring that was commonly used was vanilla and ‘ear flower’2. These different ways of cooking show a creative and vibrant diversity in the usage of the cacao pod. It is highly developed and adaptable. It shows cacao to be an essential part of the Mayan culture and diet.
The remnants of traditional Mayan way of making chocolate drink are still alive today in certain parts of Mexico among the Mayan communities. This video highlights and explains the traditional ways women make the chocolate drink in these Mayan communities.
This video shows us how labor intensive and time consuming it was to make chocolate drink in the Mayan style. The cacao beans have to shelled, roasted, dried in the sun, ground and after this long process mixed with water ready to be consumed.
Venezuelan Cacao Boom
The high-quality strain of Criollo cacao is native to Venezuela. It started being produced agriculturally at the turn of the seventeenth century. The first recorded shipment is in 1607 from La Guaira to Spain 3. This was under the influence of Hispanic colonization, those working on these plantations were slaves and laborers 4.
Here the cacao was so abundantly grown it was consumed on a regular basis by everybody, from slaves to lords. There were three different styles in consuming the cacao 5.
Cerrero– ( rough and ready, bitter ) This was just plain cacao dissolved in water with no added flavorings or sweeteners. It was widely drunk by people in the interiors.
Chorote– Made by creating solid chocolate balls which are dissolved in water, added to this is muscovado sugar. The chocolate balls were created by boiling ground cacao to separate the fats and solids. This was drunk by people in the cities as well as given to slaves and laborers for lunch and dinner.
Chocolate– Made by mixing balls of ground chocolate mixed with sugar or honey, toasted corn, seasonings such as cinnamon, ginger, and allspice. This was consumed by the Spanish elite at morning and noon meals.
The mass production led to cacao being available for everybody to consume. However what marks the social classes is by what process they made their cacao and what was added to it. Also the number of cacao beans used in the food and the time and effort of making it.
Development of industrial techniques of cacao processing
Conrad Johanes Van Houten discovered, along with his father the Cocoa press and Dutch process chocolate 6.
This created a fast and easy chocolate producing technique. It was adopted by big industries to use in their ways of chocolate production. This created a speedy and cheaper way of making good tasting chocolate.
Another process invented was the conching of chocolate. This was invented by Rudolfhe Lindt in Switzerland 7.
. It created smoother chocolate and covered the origins and original flavors and textures of the cacao bean, hence a bean sourced from anywhere of any strain could be used. The image below portrays the process of creating smoother chocolate.
These invented process allowed for the anonymity of cacao in the chocolate drink and bar. It became possible to mass produce chocolate without knowing of the origins and sourcing of the cacao bean that went into the chocolate. This created a lot of distance between the agriculture of growing cacao, strains and qualities of the pod and the consumer of the chocolate.
Mass Chocolate Production Today
This kind of mechanized industrialized mass production allows for a lot of chocolate to be produced. When chocolate production moved to such a mechanized way of being made, it became widely available for the average consumer. In today’s world chocolate is a regular household good with a large gap between knowledge of the sourcing and production of chocolate and the regular consumers of chocolate. The intensive agricultural development of cacao with the support of slave exploitation and the inventions of chocolate processing in Europe led to chocolate as is known today.

If one stands near the Chicago River fork, just by the world famous Merchandise Mart, they are struck by a familiar and enticing smell. On a good day, a large portion of downtown Chicago smells distinctly of chocolate. Following the railway lines just west of the river will lead you to the Blommer chocolate factory. Blommer currently processes almost 45% of the cacao beans in the U.S. and the Chicago headquarters stands as their largest processing plant. The smell is so strong and distinct, you can actually discern the difference between when they are making milk chocolate versus cocoa powder or dark chocolate. Traveling further down the river to the North is a strip of land that use to hold a coffee roasting plant. On a perfect day, these smells would intermingle as the roasting released their warm bitter notes on the air, reminding us of coffee and chocolate’s shared past.
(A former tumbler post allowed Chicagoans to track the chocolate scent daily)
Standing there, it begs the question about where their paths diverged. How did chocolate make the transformation from the beverage of revolutionaries and royalty to a confectionary treat to appease the masses?
By the time cacao became the darling of beverage establishments, the Old World had abandoned the Humors system of medicine. No longer were there debates as to whether chocolate was warm or cold or how to best balance it with spices. At the same time, drug crops such as tea, coffee and chocolate, which had long been associated with wealth and status, were becoming more accessible. Daily rituals were created around these beverages, often with the addition of sugar, which was growing in popularity. However, both chocolate and coffee fell out of favor as a beverage when the British East India Company increased the tea supply, causing tea prices to drop dramatically. The lower prices made it more accessible, transforming it to a national compulsion for the British. Coffee would eventually become more accessible and regain some lost ground, but rather than look to rebound as a beverage choice, chocolate evolved in the food space as a confection and flavoring.
Several different innovations helped chocolate with this evolution. Going back to its heyday as a beverage, drinking chocolate was growing in popularity in the new world. At the time, cacao was still being ground and processed by hand on matates. It was an arduous process, that took time and manpower, keeping chocolate in the hands of those who could afford it. In 1765, Dr. James Baker partnered with John Hannon to simplify the process and reduce labor. The pair rented a grist mill in Milton Lower Falls, MA, using water power to grind the chocolate. This was chocolate’s first step in to the industrial age, liberating it from the labor of hand grinding and creating a more consistent product. The company they formed, Baker chocolates, still exists today under the Kraft Heinz company.
(Baker Chocolates still stands today in Milton Falls, MA)
The next leap forward for chocolate came in 1824 from the Swiss. Coenraad Van Houten, a Swiss chemist, developed a new processing method using a hydraulic press. The press removed more than 70% of the cacao butter from the cacao nibs, leaving a cake, which could be easily turned in to powder. The cacao was then treated with alkaline, which reduced the bitterness, making for a milder, more palatable chocolate. This not only made it cheaper and easier to make in to a beverage, but the resulting powder could be used as a flavoring for cakes, and other confections, helping chocolate easily expand it’s usage beyond beverages in to foodstuffs.
(Van Houten’s Press had a multi-stage process to remove fats from the cacao nibs)
The next innovation came from the Quakers in England. In 1847, as sugar consumption was taking a drastic turn up, Joseph Fry mixed cocoa powder and sugar with melted cacao butter. The resulting mixture was malleable enough to be cast in to a mold, making the world’s first eating chocolate, and transforming chocolate from flavor to stand alone item.
The Swiss continued to innovate and in 1867 Henri Nestle, a Swiss chemist devised a way to make powder milk through a process of evaporation. This would become the first ready to mix infant formula. (which would eventually lead to a rather sorted history among the Nestle company.) This innovation proved to be useful when in 1879 Daniel Peter used it to make the first milk chocolate bar by mixing with chocolate liquor, drying the moisture out of the mix and adding cacao butter. The resulting chocolate was sweeter, smoother, and more palatable.
Not to be outdone, that same year Rudolphe Lindt invented the conching machine. The machine consisted of a flat granite base and granite roller. Cacao nibs were ground by the roller and the resulting liquor was splashed over it at the end of each roll, allowing more air to come in contact during the process. The conching process had several major advantages. First, the continual motion caused the cacao to be more finely ground, which would eventually produce a smoother chocolate. Second, the contact with the air made it easier for moisture and volatile oils to evaporate, removing some of the acidity and making for a milder, more enjoyable flavor. Lastly, and importantly, the friction in the conching process created heat, this allowed chocolate makers to reduce roasting time (as some could be done in during the conching process), which sped up chocolate production dramatically.
The last leap forward toward mass produced chocolate takes us back to the United States with Milton Hershey. In 1903, Hershey was just starting to build his chocolate empire in the center of Pennsylvania. The one process that he struggled with was processing the milk for his milk chocolate with attempts often leading to scorched or burnt milk. He finally called in John Schmalbach, who mixed skim milk with a high ratio of sugar. Using low heat evaporation, he was able to create sweetened condensed milk. The resulting product mixed beautifully with cocoa powder and cacao butter. Not only did it produce eating chocolate, but the process made the chocolate more shelf stable and able to be stored for several months. It also created a smoother mixture overall, which was easier to move through equipment and molds, allowing them to make chocolate faster and cheaper. We now had a chocolate that was cheap and fast to produce, and could stay fresh for months, allowing it to be shipped further and stocked longer. With Hershey’s the once beverage of royalty was forever transformed into an indulgence for the masses.

One step into Cambridge Naturals, a community natural health store in Cambridge, MA, and the market for organic, fair-trade, vegan, bean-to-bar, local, non-gmo, paleo, environmentally friendly and ethically sourced chocolate products is on full display. A meeting with the store’s manager & grocery lead adds another term to the list of qualities their consumer base is looking for when they step into the store – functional chocolate. This trend shows a probable correlation between what customers are willing to spend on chocolate that makes health claims, based on the way the cacao is processed and additional ingredients added that are promoted to provide nutritional benefits. The functional chocolate trend begs the question – are these health claims regarding various methods of cacao processing and healthful additives substantiated by scientific research, or are they merely a marketing gimmick? This article will analyze recent research on the health benefits of chocolate as a functional food, look at fermentation and processing differences from a nutrient perspective, and consider additional benefits of medicinal additives to chocolate in order to best answer this question.
How are functional foods different from healthy foods?
In a study published in the Academic Food Journal/Akademik (2014) that looked at the development of functional chocolate, the differences between health foods and functional foods were defined as the following:
“Functional foods are a new category of products that promise consumers improvements in targeted physiological functions” (Albak, Fatma, & Tekin, 2014, p. 19).
Whereas, “conventional ‘healthy’ foods are typically presented as types of foods contributing to a healthy diet, e.g. low-fat products, high-fibre products, or vegetables, without emphasizing the role of any single product” (Albak, Fatma, & Tekin, 2014, p. 19).
Functional foods share these characteristics:
Health benefits that can be linked to a specific product
Well-defined physiological effects are directly connected with particular components in the specific product
Scientific evidence about health effects that is used to develop specific functional products
There is novelty for the consumer with the promised benefits
Modern technology is often needed to manufacture the functional foods due to specific components being added, modified or removed (Albak, et al., 2014).
Demand for Functional Foods
The market for functional foods exists in large part due to the rising popularity of healthier products by consumers (Albak, et al., 2014). One contributor to interest in healthy products is their use as a remedy to detrimental lifestyle factors that can contribute to unyielding high levels of inflammation in the body (Jain, Parag, Pandey, & Shukla, 2015). In the book, Inflammation and Lifestyle (2015), the connection between diet and inflammation is emphasized.
“Our diet is one of the leading sources of these chronic illnesses, and changing the diet is the key to prevention and cure. A number of dietary factors, including fiber-rich foods, whole grains, fruits (especially berries), omega-3 fatty acids, antioxidant vitamins (e.g., C and E), and certain trace minerals (e.g., zinc), have been documented to reduce blood concentrations of inflammatory markers. The best way to correct and eliminate inflammation is to improve comprehensive lifestyle and dietary changes rather than taking pharmaceutical drugs, the latter of which can cause unintended harm in the form of damaging side effects” (Jain, et al., 2015, p. 143).
The authors provide this graphic to illustrate what an anti-inflammatory diet pyramid looks like in terms of specific food groups. Note that dark chocolate is positioned on the top of the pyramid.
An introduction to the benefits of superfoods and their role in an anti-inflammatory diet are explained in the publication. “An anti-inflammatory diet is one that is low in processed foods and high in fresh fruits and vegetables, seeds, sprouts, nuts and superfoods. Maca, spirulina, purple corn, wheatgrass, coconut butter and raw chocolate are a few of the health promoting superfoods that are gaining international interest” (Jain, et al., 2015, p. 144). The inclusion of “raw chocolate” in the category of superfoods versus “chocolate” warrants further examination and will be explored later in this article, but the position remains clear that evidence supports the protective benefits of chocolate as a part of a healthy diet.
Chocolate as a Functional Food
Under the category of functional foods as previously defined, chocolate, as will be further described, fulfills all the requisite characteristics. Even though the term functional food is relatively recent, the practice of consuming chocolate for its specific health benefits is centuries old. “Chocolate has been consumed as confection, aphrodisiac, and folk medicine for many years before science proved its potential health benefiting effects. Main compounds of cocoa and chocolate which contribute to human health are polyphenols that act as antioxidants and have potential anti-inflammatory, cardioprotective, antihepatotoxic, antibacterial, antiviral, antiallergenic, and anticarcinogenic properties” (Ackar, Djurdjica, Lendić, Valek,… & Nedić, 2013, p. 1). The studied physiological effects of chocolate include “reported health benefits of cocoa and dark chocolate particularly focus on cardiovascular diseases (but also showing antioxidant and anti-inflammatory effects), including increased blood flow at the brachial artery and the left descending coronary artery, decreased blood pressure, decreased platelet aggregation and increased HDL cholesterol” (Bordiga, et al., 2015, p. 840). Numerous research discoveries have shed light on the complex nature of how these protective benefits of cacao are reduced or encouraged by different methods of sourcing, processing and consuming chocolate (Jalil, & Ismail, 2008).
Polyphenols are found in many food sources including, “vegetables and fruits, green and black tea, red wine, coffee, chocolate, olives, and some herbs and spices, as well as nuts and algae” (Ackar, et al., 2013, p. 2). However, “chocolate is one of the most polyphenol-rich foods along with tea and wine” where, “results [have] indicated that dark chocolate exhibited the highest polyphenol content” (Jalil, & Ismail, 2008, p. 2194). In unfermented cacao beans, there are three main groups of polyphenols, “flavan-3-ols or catechins, anthocyanins, and proanthocyanidins” (Ackar, et al., 2013, p. 2). Differences in cacao genetics or varieties and country of origin show varying levels of polyphenols by up to 4-fold (Jalil, & Ismail, 2008). “Criollo cultivars contained higher levels of procyanidins than Forastero and Trinitario beans. In addition, crop season and country of origin have impact on polyphenols in cocoa beans” (Ackar, et al., 2013, p. 2). Findings regarding polyphenol level by country of origin are contentious but include, “highest phenolic content was in Malaysian beans followed by Sulawesian, Ghanian and Côte d’Ivore” (Jalil, & Ismail, 2008, p. 2201) and “cocoa beans and processed products from Ecuador showed the highest levels of anthocyanins, followed by Nigeria and Cameroon” (Bordiga, et al., 2015, p. 840). Due to additional factors besides country of origin and genetic variation influencing the polyphenols in cacao, inclusion of the effects of processing cacao on flavor and polyphenol content is important to understand health claims made regarding the finished product, chocolate.
Processing cacao beans (namely the stages of fermentation and drying), and roasting in the chocolate making process greatly affect polyphenol content of the finished product (Ackar, et al., 2013; Bordiga, et al., 2015). “Due to these factors, the ratio and types of these components found in cocoa beans are unlikely to be the same as those found in the finished products” (Bordiga, et al., 2015, p. 841). For functional chocolate enthusiasts driving market trends, the balance between healthy and protective benefits of polyphenols and the effects on their levels through processing are of particular interest. “All these processes are needed to develop characteristic cocoa aroma. Polyphenols give astringent and bitter aroma to cocoa and contribute to reduced perception of “cocoa flavour” by sensory panel. However, nowadays processes are conducted in such manner to preserve as much polyphenol as possible with maintaining satisfactory aroma” (Ackar, et al., 2013, p. 2). The debate about the purpose of chocolate is hereby noted between the sensory experience – the aroma development, especially in the roasting stages, versus consumption for health effects with less regard to smell, taste and gustatory pleasure.
The search for a sweet spot between these poles is a lucrative area for producers and retail establishments. As described earlier, development of functional food into specific products uses scientific evidence about health effects, where modern technology is often needed to manufacture those products, in order to observe targeted physiological effects or functions (Albak, et al., 2014).
“Generally, as cocoa beans were further processed, the levels of anthocyanins and flavan-3-ols decreased. The largest observed losses of phenolics occurred during roasting. A progressive decreasing trend in polyphenol concentration was observed in the other processed samples as well. Despite the original content of polyphenols in raw cocoa beans, technological processes imply a significant impact on cocoa quality, confirming the need of specific optimisation to obtain high value chocolate” (Bordiga, et al., 2015, p. 840).
In order to preserve antioxidant quality through dark-chocolate products with “high flavonoid contents…these chocolates are produced by controlling bean selection, fermentation, and reduced heat and alkalization treatments” (Jalil, et al., 2008, p. 2201). Although one of the most detrimental effects of processing on polyphenol and antioxidant levels is alkalization (or dutching) of cocoa powder (Ackar, et al., 2013; Jalil, et al., 2008), even the fermentation process significantly reduces flavonoid levels by up to 90% (Jalil, et al., 2008). However, in the search for the sweet spot between flavor and health benefits, fermentation presents a way to reduce bitter compounds due to the presence of flavonoids and polyphenols (Jalil, et al., 2008) and enhance flavor before roasting or further processing like alkalization. For example, some “manufacturers tend to remove [flavonoids] in large quantities to enhance taste quality… the manufacturers tend to prefer Ghanian cocoa beans, which are well-fermented and flavorful than that of Dominican or Indonesian beans, which are considered as less fermented and have low quality cocoa flavor” (Jalil, et al., 2008, p. 2203). In Crafack’s study (2013), besides genetic flavor potentials of cacao beans, fermentation is cited as the most important factor influencing cocoa’s flavor potential.
“A properly conducted fermentation process is considered a prerequisite for the production of high quality chocolates since inadequately fermented cocoa beans will fail to produce cocoa specific aroma compounds during subsequent processing” (Crafack, Petersen, Eskildsen, Petersen, Heimdal, & Nielsen, 2013, p. 1).
In a later study by Crafack (2014), microorganism differences between fermentation practices are shown to produce variations in cacao flavor profiles. “Despite the importance of a properly conducted fermentation process, poor post-harvest practices, in combination with the unpredictable spontaneous nature of the fermentations, often results in sub-optimal flavour development…A microbial fermentation process therefore seems essential for developing the full complexity of compounds which characterises cocoa aroma. In conclusion, the results of the present study show that the volatile aroma profile of chocolate can be influenced using starter cultures” (Crafack, 2014, p. 1). Further research that builds on Crafack’s findings was published by Kadow (2015), explaining the role of multiple factors in the country of origin that characterize the fermentation process.
“During this in most cases spontaneous fermentation of the fruit pulp surrounding the seeds, the pulp is degraded by yeasts and bacteria. This degradation results in heat and organic acid formation. Heat effect and tissue acidification are the key parameters guiding flavour precursor formation. Accordingly, not microorganisms themselves but exclusively their metabolites are necessary for successful fermentation” (Kadow, Niemenak, Rohn, and Lieberei, 2015, p. 357).
This study aimed to further the development of standardization and mechanization of cocoa fermentation for the benefit of cacao production quality purposes. On the ranges of heat tested from fermenting heaps of cacao beans, 30 °C to a maximum of 50 °C was obtained after 24 h of fermentation at the inner part of the heap (Jespersen, Nielsen, Hønholt, and Jakobsen, 2005).
Finally, as an interesting note about polyphenol changes in cacao during fermentation, although “unripe and ripe cacao pods contain solely (−)-epicatechin and (+)-catechin. During fermentation, levels of both of these compounds were reduced, but (−)-catechin was formed due to heat-induced epimerization” (Ackar, et al., 2013, p. 2). These findings warrant more studies on the changes that happen during cacao fermentation, where although certain protective antioxidant levels decrease, other chemical compounds are formed due to the process of heat due to microorganism metabolites and acidification to the bean tissue.
After fermentation, the beans are dried to reduce water content for safe transport and storage of the cacao before further processing by chocolate manufactures. “During drying, additional loss of polyphenol occurs, mainly due to nonenzymatic browning reactions” (Ackar, et al., 2013, p. 2) where “high temperatures and prolonged processing times will decrease the amount of catechins” (Jalil, et al., 2008, p.2203). The dried cacao is then shipped to the chocolate manufacturer where roasting is often performed. The roasting and generally the further processing of cacao degrades the levels of polyphenols by triggering the oxidation process (Ackar, et al., 2013; Bordiga, et al., 2015).
Conching is a process of agitation of chocolate mass at temperatures above 50 °C that is used to refine both the cocoa solids and sugar crystals to change the taste, smell, flavor, texture (mouthfeel) and viscosity of chocolate (Chocolate Alchemy, 2016; Di Mattia, Martuscelli, Sacchetti, Beheydt, Mastrocola, & Pittia, 2014) Different procedures for conching exist, including Long Time Conching (LTC) and Short Time Conching (STC). A study by Di Mattia (2014) done on these two conching processes and the implications for bioactive compounds and antioxidant activity found interesting results. The publication stressed the importance of time/temperature combinations as process parameters “to modulate and increase the functional properties of some foods” (Di Mattia, et al., 2014, pp.367-368). In the study, STC consisted of “a dry step at 90 °C for 6 h and then a wet step at 60°C for 1h,” while LTC involved, “a dry step at 60°C for 6 h and a then wet step at the same conditions (60 °C, 6 h)” (Di Mattia, et al., 2014, p. 368). The results of the analysis on phenolic content, antioxidant values defined as radical scavenging properties showed, “that the conching process, and the LTC in particular, determined an improvement of the antiradical and reducing properties of chocolate” (Di Mattia, et al., 2014, p.372). Recommendation for further studies was suggested to “optimize the conching process for the modulation of the functional properties,” (Di Mattia, et al., 2014, p.372) but the results remain in favor of longer time and lower temperature processing to preserve health benefits in chocolate during the conching phase.
From the perspective of chocolate makers, assessing combinations of ingredients/additives that can either help or hinder protective compounds in chocolate – including polyphenols and bioavailability, is important. Jalil, & Ismail’s review (2008), considered, “both bioavailability and antioxidant status [important] in determining the relationship between cocoa flavonoids and health benefits” (Jalil, et al., 2008, pp. 2194-2195). Studies focused on epicatechin from chocolate found the polyphenols, “rapidly absorbed by humans, with plasma levels detected after 30min of oral digestion, peaking after 2-3 h and returning to baseline after 6–8 h. In addition, cumulative effect in high daily doses was recorded” (Ackar, et al., 2013, p. 2). Interestingly, an argument for the benefits of chocolate’s sweetened and rich composition – if cocoa butter and some type of sweetener is used in processing – is explained where the “presence of sugars and oils generally increases bioavailability of polyphenols, while proteins, on the other hand, decrease it” (Ackar, et al., 2013, p. 2). Milk chocolate lovers may be disappointed to find that, “milk proteins reduce bioavailability of epicatechin in chocolate confectionary…[with] reported inhibition of in vivo antioxidant activity of chocolate by addition of milk either during manufacturing process or during ingestion” (Ackar, et al., 2013, p. 2).
Additional health properties of cacao found especially in dark chocolate, apart from polyphenols, may have a role to play in reports of chocolate cravings and their use as functional food. Theses beneficial components include “methylxanthines, namely caffeine, theobromine, and theophylline” (Jalil, et al., 2008, p. 2197) “peptides, and minerals” (Jalil, et al., 2008, p. 2200). “Theobromine is a psychoactive compound without diuretic effects” (Jalil, et al., 2008, p. 2198). “Cocoa is also rich in proteins. Cocoa peptides are generally responsible for the flavour precursor formation” (Jalil, et al., 2008, p. 2199). Lastly, “minerals are one of the important components in cocoa and cocoa products. Cocoa and cocoa products contained relatively higher amount of magnesium compared to black tea, red wine, and apples” (Jalil, et al., 2008, p. 2200).
A well supported rule of thumb for finding high antioxidant capacity functional chocolate is to look for the percentage of non-fat cocoa solids (NFCS) in chocolate products to determine total phenolic content (Jalil, et al., 2008; Vinson, & Motisi, 2015) “Dark chocolates contain the highest NFCS among the different types of chocolates” (Jalil, et al., 2008, p. 2204) However, due to percentages of cocoa solids on on chocolate labels including polyphenol-free cocoa butter, the accuracy of this measure is not always correct and can lead to overestimating polyphenol content in certain types of chocolate (Jalil, et al., 2008, p. 2204). That said, a recent study by Vinson and Motisi (2015), performed on commercial chocolate bars found “a significant and linear relationship between label % cocoa solids and the antioxidant assays as well as the sum of the monomers.” From which they concluded that, “consumers can thus rationally choose chocolate bars based on % cocoa solids on the label” (Vinson, & Motisi, 2015, p. 526).
Additions to Functional Chocolate
In health food stores like Cambridge Naturals and Deborah’s Natural Gourmet in Concord, MA, the presence of functional chocolate with additional health boosting ingredients is prevalent. The validity of these claims to improve focus, enhance libido and energy, and other desirable improved physiological functions, based on herbs, powders and additional superfoods mixed with cacao, is intriguing. A study by Albak and Tekin (2014), found that mixing aniseed, ginger, and cinnamon into the dark chocolate mix before conching, “increased the total polyphenol content while they decreased the melting properties of dark chocolate after conching” (Albak, et al., 2014, p. 19).
Other resources that further elucidate specific findings on these superfoods, herbs and spices include:
Afolabi Clement Akinmoladun, Mary, Tolulope Olaleye, and Ebenezer Olatunde Farombi. “Cardiotoxicity and Cardioprotective Effects of African Medicinal Plants.” Toxicological Survey of African Medicinal Plants (2014): 395. This publication includes information on gingko, turmeric among other additives to functional chocolate and how protective vascular effects are formed.
Some consideration for the popularity of raw chocolate, which is used as the base of many functional chocolate products, deserves attention. As explained, there are many reasons chocolate can be considered a functional food, especially due to specific health promoting compounds like polyphenols and flavonoids, peptides, theobromine and minerals present in cacao and in chocolate. Unfortunately, overwhelming scientific evidence points to the detrimental effects on these compounds from processing, especially by heat. “Flavanols largely disappear once the cocoa bean is heated, fermented and processed into chocolate. In other words, making chocolate destroys the very ingredient that is supposed to make it healthy” (Crowe, 2015). Raw chocolate, by the standards of raw foodism, means that food is not supposed to be heated above 118 degrees Fahrenheit in order to preserve enzymes. This seems tricky to prove especially when chocolate makers receive cocoa beans from various countries of origin where fermenting and drying practices are not under their direct supervision. Some companies remedy this issue with bean-to-bar practices that ensure they have seen and approved the process that cacao beans undergo before shipment to the company’s own processing facilities, where low temperature winnowing, grinding and conching is under their complete control. The bean-to-bar method (See Taza’s Bean-to-Bar and Direct Trade process) also provides assurance that cacao is ethically (sometimes for organic and wild-crafted cacao if so desired) sourced. These initiatives often promote more sustainable and better processed cacao, which means higher quality cacao for both the farmer, manufacturer and consumer. For these reasons, the popularity of raw cacao seems to fit into the development of functional foods where the consumer is able to enjoy a sometimes more bitter, medicinal tasting chocolate in the anticipation of a powerful physiological boost and a clearer conscience due to sourcing methods.
In the case of Yes Cacao, their Karma MellOwl botanical chocolate bar contains 41% cacao butter, and 59% botanicals which results in a deliciously complex, albeit golden colored bar due to the cocoa butter and turmeric content. Non-fat cacao solids which provide the main anti-inflammatory benefits of cacao are missing, but are replaced with other superfoods, spices and adaptogenic herbs like lucuma, maca, yacon, lion’s mane mushrooms, gingko, turmeric, pine pollen, cinnamon, bacopa, and gynostemma. The creators of the bars deem them functional medicine, as they combine cacao solids and sundried cane juice as a base for superfood and medicinal enhancements. In this video, Justin Frank Polgar recommends that Yes Cacao bars are eaten daily as a staple enhancement for ideal human functionality.
Other raw chocolate companies that are focus on functional chocolate using additional superfoods, spices and herbs include:
Trends in functional foods heading in the direction of ‘naturally healthy’
From the perspective of growers, producers and consumers who want a high quality, healthful and good tasting chocolate product, the scientific findings that support the ideal balance between flavor and preservation of health promoting properties of cacao, are significant. The ideal way to conserve protective, antioxidant and anti-inflammatory benefits warrants consideration with the changes in polyphenol content during processing of cacao from raw bean, through fermentation to roasting, conching and mixing with other ingredients. Raw chocolate seems a good way to navigate this balance. Meanwhile, mass produced commercial chocolate companies or “big chocolate” continue to move their products in the direction of high quality premium chocolate and adopting new manufacturing processes in order to preserve cacao’s protective effects. The overarching trend uniting premium, natural and healthful ingredients is referred to in the food industry as naturally healthy foods. “This idea of using food to manage health may, in part, help explain growing consumer interest in fresh, natural and organic products”(Gagliardi, 2015). The melding of healthy, natural and functional foods to chocolate production reflects consumer preferences and industry recognition of the role diet plays on health and provides insights into the future of food. For now, medicinally enhanced, raw, naturally healthy, and functional chocolate seems light years ahead of other natural foods on the market today.
Author’s Note: While researching and writing this article the author happily consumed a great deal of functional, raw and medicinal chocolate and can attest to the powerful effects that far surpass conventional and even ‘premium chocolates’.

Throughout the 1800s, the consumption of chocolate and sugar increased significantly. This was due to a combination of decreased sugar prices and technological advancements in the chocolate production. Sugar went from being a rarity to a staple of many people’s diets. This was important to the production of chocolate because sugar was and still is a major ingredient in chocolate. Several people also invented new machines and methods that made it easier for chocolate to be available for the masses. Without the decrease in sugar prices and these inventions, chocolate would not have become as important a part of society as it is today.
In 1828, Van Houten made one of the first big technological advancements in chocolate production by inventing the hydraulic press. The hydraulic press separates chocolate liquor into cocoa powder and cocoa butter. This made it both cheaper and easier to produce chocolate. “Van Houten’s invention of the defatting and alkalizing processes made possible the large-scale manufacture of cheap chocolate for the masses, in both powdered and solid form” (Coe & Coe 235). His hydraulic press is pictured below. It uses high amounts of pressure to separate the chocolate liquor. Without this invention it would have been much more difficult for further advancements in chocolate production to occur, like chocolate bars.
Thanks to Van Houten’s invention of the hydraulic press, another man named Fry was able to invent the chocolate bar. As Coe & Coe explains, “[w]ith Van Houten’s breakthrough, the Fry enterprise-and the Fry dynasty-was ready to move into high gear… A milestone was passed in 1847, when the Fry firm found a way to mix a blend of cocoa powder and sugar with melted cacao butter… this produced a thinner, less viscous paste which could be cast into a mold… this was the world’s first true eating chocolate” (Coe & Coe 241). Without the separation of chocolate liquor into cocoa power and butter, it would have been difficult to create a mixture that could have been combined in such a way. Below is an image of an advertisement for Fry’s chocolate bars. This image shows the shift from chocolate as something that only the rich might eat into something available for the masses, and specifically poorer families and children. Sugar and chocolate became a replacement for other foods as their prices decreased. The lack of time required for preparation also contributed to this.
In 1840-1870 there were big price drops in sugar. Mintz explains that “In the 1800s, the national consumption was about 300 million pounds per year; once the duties began to be equalized and the price to drop, consumption rose, to a billion pounds in 1852… Without the price drops, consumption could not have risen so fast” (243). If sugar prices had not decreased it would not have been so easy for chocolate bars like Fry’s to be made available to the general public. It is also interesting that “the biggest sucrose consumers, especially after 1850, came to be the poor, whereas before 1750 they had been the rich” (Mintz 148). This is especially important because part of the reason that chocolate is so popular today is that it is affordable for everyone. It is also interesting to note that Fry was able to produce chocolate bars around the same time that sugar prices drop. This likely would not have been possible without the drop.
In 1879, Rudolphe Lindt invented “conching,” which improved the quality of chocolate making (Coe & Coe 248). Conching led to an important improvement in the taste of chocolate. The taste and texture of chocolate that most recognize today is largely thanks to Lindt. As Coe & Coe explains, “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. Before Lindt, eating chocolate was usually coarse and gritty; now it had achieved such a degree of suavity and mellowness” (248). A conche is shown in the image below. This specific machine was used at Hershey. The ridges and rollers pictured below create this “rock-and-roll” treatment. In some factories, like Hershey’s, there would be entire rooms filled with conche machines.
The production of chocolate was revolutionized thanks to the above inventions and the decrease in the cost of sugar. Without these things, chocolate would likely not be as pervasive in society as it is today.

In Baroque Europe, chocolate was linked with notions of status and class. The elite of Spain, Italy, France, and Britain consumed chocolate in the form of beverages and foods to flaunt their wealth. They used extravagant serving pots, cups, and saucers (like the one below) which demonstrate the importance of material culture during this time period. However, by the end of the nineteenth century, chocolate was popularized across many parts of the world as well as across various socioeconomic groups. The spread of chocolate can be linked to the role chocolate played in social interactions, to the democratization and industrialization of sugar, and to the inventions that made it possible to expand its production and the forms it took.
When chocolate was first introduced as a medicine around 1100 CE, it was primarily used to cure bodily ailments, to stimulate the nervous system, and to aid in digestion (Dillinger et al., 2000). In the mid-1500s, chocolate became popular among the aristocracy and the wealthy in Europe. The breadwinner in the family was first entitled to meat the family could afford, but women and children consumed chocolate to supplement their scarce portions in order to obtain enough calories. The use of chocolate evolved from a luxury to a commodity as it became tied to social life. The first Chocolate House opened in London in 1657 (Loveman, 29). “Food and drink, not surprisingly, reflected [the] economic, social, and religious cleavages…chocolate was [characterized] as southern and Catholic and aristocratic…” (Coe and Coe, 200). Chocolate acquired new meaning in European countries as its consumption became highly social and symbolic of wealth. As people used chocolate to connect and interact with one another, its consumption took on new meaning, and its previous status as an indulgent good transitioned into a good that became worthy of the expense. Chocolate became more popular, and transitioned from a symbolic form of power to a democratizer as it became more widely available (Mintz, 91).
According to Mintz, “by no later than 1800, sugar had become a necessity – albeit a costly and rare one – in the diet of every English person; by 1900, it was supplying nearly one-fifth of calories in the English diet” (6). Over the course of the eighteenth and nineteenth centuries, the democratization of sugar occurred. Sugar decreased in cost and became easier for commoners to acquire through the use of cheap and brutal skilled labor of enslaved people. While there was opposition to slave labor, it allowed for the price of chocolate to fall. Its production thus expanded, and more commoners were granted access to this commodity. Liverpool and Manchester turned into gigantic cities as a result of “the exchange of their produce with that raised by the American slaves” (Merivale, Lecture 6).
During the nineteenth century, a number of inventions allowed for the further spread of the popularity of chocolate. The series of innovations began with the hydraulic press, invented by Coenraad Johannes Van Houten in 1828, which relieved the labor that was previously needed for grinding cacao. In 1847, Joseph Fry invented the first chocolate bar. A few decades later, Henri Nestle and Daniel Peter created milk chocolate (in 1867 and 1879, respectively). Finally, Rudolphe Lindt implemented the conching process in 1879, which allowed for chocolate to be blended and smoothed (Lecture 5). Through the implementation of these new machines and inventions, the mass production of chocolate became possible, as the taste and consistency of chocolate could be streamlined and managed in large quantities by its producers.
While chocolate was once restricted to the elite in Europe, as it was expensive and inaccessible, it became popular around the world throughout the eighteenth and nineteenth centuries. First, chocolate became more widely consumed as a result of its social implications. Later, as consumers demanded chocolate as a necessity (rather than as a luxury good), people were enslaved to increase its production possibilities. Finally, new processes enabled its mass production as it could be streamlined and involved less human and manual labor. As chocolate became less expensive, technologies allowed for its popularity in the form of cakes and chocolate bars. Most recently, chocolate companies have turned to advertising to encourage its further consumption, often overemphasizing its nutritious value in the process.
