Chocolate is a preparation of roasted and ground cacao seeds that is made in the form of a liquid, paste, or in a block, which may also be used as a flavoring ingredient in other foods. The earliest signs of use are associated with Olmec sites (within what would become Mexico’s post-colonial territory) suggesting consumption of chocolate beverages, dating from 19 centuries BCE.The majority of Mesoamerican people made chocolate beverages, including the Maya and Aztecs. The word chocolate is derived from the Spanish word chocolate, deriving in turn from the Classical Nahuatl word xocolātl.
The seeds of the cacao tree have an intense bitter taste and must be fermented to develop the flavor. After fermentation, the beans are dried, cleaned, and roasted. The shell is removed to produce cacao nibs, which are then ground to cocoa mass, unadulterated chocolate in rough form. Once the cocoa mass is liquefied by heating, it is called chocolate liquor. The liquor may also be cooled and processed into its two components: cocoa solids and cocoa butter. Baking chocolate, also called bitter chocolate, contains cocoa solids and cocoa butter in varying proportions, without any added sugar. Powdered baking cocoa, which contains more fiber than cocoa butter, can be processed with alkali to produce dutch cocoa. Much of the chocolate consumed today is in the form of sweet chocolate, a combination of cocoa solids, cocoa butter or added vegetable oils, and sugar. Milk chocolate is sweet chocolate that additionally contains milk powder or condensed milk. White chocolate contains cocoa butter, sugar, and milk, but no cocoa solids.
Chocolate is one of the most popular food types and flavors in the world, and many foodstuffs involving chocolate exist, particularly desserts, including cakes, pudding, mousse, chocolate brownies, and chocolate chip cookies. Many candies are filled with or coated with sweetened chocolate. Chocolate bars, either made of solid chocolate or other ingredients coated in chocolate, are eaten as snacks. Gifts of chocolate molded into different shapes (such as eggs, hearts, coins) are traditional on certain Western holidays, including Christmas, Easter, Valentine's Day, and Hanukkah. Chocolate is also used in cold and hot beverages, such as chocolate milk and hot chocolate, and in some alcoholic drinks, such as creme de cacao.
Although cocoa originated in the Americas, West African countries, particularly Côte d'Ivoire and Ghana, are the leading producers of cocoa in the 21st century, accounting for some 60% of the world cocoa supply.
With some two million children involved in the farming of cocoa in West Africa, child slavery and trafficking were major concerns in 2018.International attempts to improve conditions for children were failing because of persistent poverty, absence of schools, increasing world cocoa demand, more intensive farming of cocoa, and continued exploitation of child labor.
Chocolate has been prepared as a drink for nearly all of its history. For example, one vessel found at an Olmec archaeological site on the Gulf Coast of Veracruz, Mexico, dates chocolate's preparation by pre-Olmec peoples as early as 1750 BC.On the Pacific coast of Chiapas, Mexico, a Mokaya archaeological site provides evidence of cacao beverages dating even earlier, to 1900 BC. The residues and the kind of vessel in which they were found indicate the initial use of cacao was not simply as a beverage, but the white pulp around the cacao beans was likely used as a source of fermentable sugars for an alcoholic drink.
An early Classic-period (460–480 AD) Mayan tomb from the site in Rio Azul had vessels with the Maya glyph for cacao on them with residue of a chocolate drink, suggests the Maya were drinking chocolate around 400 AD. Documents in Maya hieroglyphs stated chocolate was used for ceremonial purposes, in addition to everyday life. The Maya grew cacao trees in their backyards, and used the cacao seeds the trees produced to make a frothy, bitter drink.
By the 15th century, the Aztecs gained control of a large part of Mesoamerica and adopted cacao into their culture. They associated chocolate with Quetzalcoatl, who, according to one legend, was cast away by the other gods for sharing chocolate with humans,and identified its extrication from the pod with the removal of the human heart in sacrifice. In contrast to the Maya, who liked their chocolate warm, the Aztecs drank it cold, seasoning it with a broad variety of additives, including the petals of the Cymbopetalum penduliflorum tree, chile pepper, allspice, vanilla, and honey.
The Aztecs were unable to grow cacao themselves, as their home in the Mexican highlands was unsuitable for it, so chocolate was a luxury imported into the empire.Those who lived in areas ruled by the Aztecs were required to offer cacao seeds in payment of the tax they deemed "tribute". Cocoa beans were often used as currency. For example, the Aztecs used a system in which one turkey cost 100 cacao beans and one fresh avocado was worth three beans.
The Maya and Aztecs associated cacao with human sacrifice, and chocolate drinks specifically with sacrificial human blood.The Spanish royal chronicler Gonzalo Fernández de Oviedo y Valdés described a chocolate drink he had seen in Nicaragua in 1528, mixed with achiote: "because those people are fond of drinking human blood, to make this beverage seem like blood, they add a little achiote, so that it then turns red. ... and part of that foam is left on the lips and around the mouth, and when it is red for having achiote, it seems a horrific thing, because it seems like blood itself."
Until the 16th century, no European had ever heard of the popular drink from the Central American peoples.Christopher Columbus and his son Ferdinand encountered the cacao bean on Columbus's fourth mission to the Americas on 15 August 1502, when he and his crew seized a large native canoe that proved to contain cacao beans among other goods for trade. Spanish conquistador Hernán Cortés may have been the first European to encounter it, as the frothy drink was part of the after-dinner routine of Montezuma. José de Acosta, a Spanish Jesuit missionary who lived in Peru and then Mexico in the later 16th century, wrote of its growing influence on the Spaniards:
Loathsome to such as are not acquainted with it, having a scum or froth that is very unpleasant to taste. Yet it is a drink very much esteemed among the Indians, wherewith they feast noble men who pass through their country. The Spaniards, both men, and women, that are accustomed to the country, are very greedy of this Chocolaté. They say they make diverse sorts of it, some hot, some cold, and some temperate, and put therein much of that 'chili'; yea, they make paste thereof, the which they say is good for the stomach and against the catarrh.
While Columbus had taken cacao beans with him back to Spain,chocolate made no impact until Spanish friars introduced it to the Spanish court. After the Spanish conquest of the Aztecs, chocolate was imported to Europe. There, it quickly became a court favorite. It was still served as a beverage, but the Spanish added sugar, as well as honey (the original sweetener used by the Aztecs for chocolate), to counteract the natural bitterness. Vanilla, another indigenous American introduction, was also a popular additive, with pepper and other spices sometimes used to give the illusion of a more potent vanilla flavor. Unfortunately, these spices tended to unsettle the European constitution; the Encyclopédie states, "The pleasant scent and sublime taste it imparts to chocolate have made it highly recommended; but a long experience having shown that it could potentially upset one's stomach", which is why chocolate without vanilla was sometimes referred to as "healthy chocolate". By 1602, chocolate had made its way from Spain to Austria. By 1662, Pope Alexander VII had declared that religious fasts were not broken by consuming chocolate drinks. Within about a hundred years, chocolate established a foothold throughout Europe.
The new craze for chocolate brought with it a thriving slave market, as between the early 1600s and late 1800s, the laborious and slow processing of the cacao bean was manual.Cacao plantations spread, as the English, Dutch, and French colonized and planted. With the depletion of Mesoamerican workers, largely to disease, cacao production was often the work of poor wage laborers and African slaves. Wind-powered and horse-drawn mills were used to speed production, augmenting human labor. Heating the working areas of the table-mill, an innovation that emerged in France in 1732, also assisted in extraction.
New processes that sped the production of chocolate emerged early in the Industrial Revolution. In 1815, Dutch chemist Coenraad van Houten introduced alkaline salts to chocolate, which reduced its bitterness.A few years thereafter, in 1828, he created a press to remove about half the natural fat (cocoa butter or cacao butter) from chocolate liquor, which made chocolate both cheaper to produce and more consistent in quality. This innovation introduced the modern era of chocolate.
Known as "Dutch cocoa", this machine-pressed chocolate was instrumental in the transformation of chocolate to its solid form when, in 1847, English chocolatier Joseph Fry discovered a way to make chocolate moldable when he mixed the ingredients of cocoa powder and sugar with melted cocoa butter.Subsequently, his chocolate factory, Fry's of Bristol, England, began mass-producing chocolate bars, Fry's Chocolate Cream, launched in 1866, and they became very popular. Milk had sometimes been used as an addition to chocolate beverages since the mid-17th century, but in 1875 Swiss chocolatier Daniel Peter invented milk chocolate by mixing a powdered milk developed by Henri Nestlé with the liquor. In 1879, the texture and taste of chocolate was further improved when Rudolphe Lindt invented the conching machine.
Besides Nestlé, several notable chocolate companies had their start in the late 19th and early 20th centuries. Rowntree's of York set up and began producing chocolate in 1862, after buying out the Tuke family business. Cadbury was manufacturing boxed chocolates in England by 1868.Manufacturing their first Easter egg in 1875, Cadbury created the modern chocolate Easter egg after developing a pure cocoa butter that could easily be molded into smooth shapes. In 1893, Milton S. Hershey purchased chocolate processing equipment at the World's Columbian Exposition in Chicago, and soon began the career of Hershey's chocolates with chocolate-coated caramels.
The Baker Chocolate Company, which makes Baker's Chocolate, is the oldest producer of chocolate in the United States. In 1765 Dr. James Baker and John Hannon founded the company in Boston. Using cocoa beans from the West Indies, the pair built their chocolate business, which is still in operation.
White chocolate was first introduced to the U.S. in 1946 by Frederick E. Hebert of Hebert Candies in Shrewsbury, Massachusetts, near Boston, after he had tasted "white coat" candies while traveling in Europe.
Cacao, pronounced by the Olmecs as kakawa, BC or earlier. The word "chocolate" entered the English language from Spanish in about 1600. The word entered Spanish from the word xocolātl in Nahuatl, the language of the Aztecs. The origin of the Nahuatl word is uncertain, as it does not appear in any early Nahuatl source, where the word for chocolate drink is cacahuatl, "cacao water". It is possible that the Spaniards coined the word (perhaps in order to avoid caca, a vulgar Spanish word for "faeces") by combining the Yucatec Mayan word chocol, "hot", with the Nahuatl word atl, "water". Another proposed etymology derives it from the word chicolatl, meaning "beaten drink", which may derive from the word for the frothing stick, chicoli. The term "chocolatier", for a chocolate confection maker, is attested from 1888.dates to 1000
Several types of chocolate can be distinguished. Pure, unsweetened chocolate, often called "baking chocolate", contains primarily cocoa solids and cocoa butter in varying proportions. Much of the chocolate consumed today is in the form of sweet chocolate, which combines chocolate with sugar.
Milk chocolate is sweet chocolate that also contains milk powder or condensed milk. In the UK and Ireland, milk chocolate must contain a minimum of 20% total dry cocoa solids; in the rest of the European Union, the minimum is 25%.
White chocolate, although similar in texture to that of milk and dark chocolate, does not contain any cocoa solids that impart a dark color. In 2002, the US Food and Drug Administration established a standard for white chocolate as the "common or usual name of products made from cacao fat (i.e., cocoa butter), milk solids, nutritive carbohydrate sweeteners, and other safe and suitable ingredients, but containing no nonfat cacao solids".
Dark chocolate is produced by adding fat and sugar to the cacao mixture. The U.S. Food and Drug Administration calls this "sweet chocolate", and requires a 15% concentration of chocolate liquor. European rules specify a minimum of 35% cocoa solids. As of 2017 [update] , there is no high-quality evidence that dark chocolate affects blood pressure significantly or provides other health benefits.A higher amount of cocoa solids indicates more bitterness. Semisweet chocolate is dark chocolate with low sugar content. Bittersweet chocolate is chocolate liquor to which some sugar (typically a third), more cocoa butter and vanilla are added. It has less sugar and more liquor than semisweet chocolate, but the two are interchangeable in baking. It is also known to last for two years if stored properly.
Unsweetened chocolate is pure chocolate liquor, also known as bitter or baking chocolate. It is unadulterated chocolate: the pure, ground, roasted chocolate beans impart a strong, deep chocolate flavor. It is typically used in baking or other products to which sugar and other ingredients are added. Raw chocolate, often referred to as raw cacao, is always dark and a minimum of 75% cacao.
Poorly tempered or untempered chocolate may have whitish spots on the dark chocolate part, called chocolate bloom; it is an indication that sugar or fat has separated due to poor storage. It is not toxic and can be safely consumed.
Roughly two-thirds of the entire world's cocoa is produced in West Africa, with 43% sourced from Côte d'Ivoire, as of 2007 [update] , child labor is a common practice to obtain the product. According to the World Cocoa Foundation, in 2007 some 50 million people around the world depended on cocoa as a source of livelihood. As of 2007 [update] in the UK, most chocolatiers purchase their chocolate from them, to melt, mold and package to their own design. According to the WCF's 2012 report, the Ivory Coast is the largest producer of cocoa in the world. The two main jobs associated with creating chocolate candy are chocolate makers and chocolatiers. Chocolate makers use harvested cacao beans and other ingredients to produce couverture chocolate (covering). Chocolatiers use the finished couverture to make chocolate candies (bars, truffles, etc.).where,
Production costs can be decreased by reducing cocoa solids content or by substituting cocoa butter with another fat. Cocoa growers object to allowing the resulting food to be called "chocolate", due to the risk of lower demand for their crops.
The sequencing in 2010 of the genome of the cacao tree may allow yields to be improved.Due to concerns about global warming effects on lowland climate in the narrow band of latitudes where cacao is grown (20 degrees north and south of the equator), the commercial company Mars, Incorporated and the University of California, Berkeley are conducting genomic research in 2017–18 to improve the survivability of cacao plants in hot climates.
Chocolate is made from cocoa beans, the dried and fermented seeds of the cacao tree ( Theobroma cacao ), a small, 4–8 m tall (15–26 ft tall) evergreen tree native to the deep tropical region of the Americas. Recent genetic studies suggest the most common genotype of the plant originated in the Amazon basin and was gradually transported by humans throughout South and Central America. Early forms of another genotype have also been found in what is now Venezuela. The scientific name, Theobroma , means "food of the gods". The fruit, called a cacao pod, is ovoid, 15–30 cm (6–12 in) long and 8–10 cm (3–4 in) wide, ripening yellow to orange, and weighing about 500 g (1.1 lb) when ripe.
Cacao trees are small, understory trees that need rich, well-drained soils. They naturally grow within 20° of either side of the equator because they need about 2000 mm of rainfall a year, and temperatures in the range of 21 to 32 °C (70 to 90 °F). Cacao trees cannot tolerate a temperature lower than 15 °C (59 °F).
The three main varieties of cacao beans used in chocolate are criollo, forastero, and trinitario.
Representing only 5% of all cocoa beans grown as of 2008 [update] , criollo is the rarest and most expensive cocoa on the market, and is native to Central America, the Caribbean islands and the northern tier of South American states. The genetic purity of cocoas sold today as criollo is disputed, as most populations have been exposed to the genetic influence of other varieties.
Criollos are particularly difficult to grow, as they are vulnerable to a variety of environmental threats and produce low yields of cocoa per tree. The flavor of criollo is described as delicate yet complex, low in classic chocolate flavor, but rich in "secondary" notes of long duration.
The most commonly grown bean is forastero,a large group of wild and cultivated cacaos, most likely native to the Amazon basin. The African cocoa crop is entirely made up of forastero. They are significantly hardier and of higher yield than criollo. The source of most chocolate marketed, forastero cocoas are typically strong in classic "chocolate" flavor, but have a short duration and are unsupported by secondary flavors, producing "quite bland" chocolate.
Trinitario is a natural hybrid of criollo and forastero. Trinitario originated in Trinidad after an introduction of forastero to the local criollo crop. Nearly all cacao produced over the past five decades is of the forastero or lower-grade trinitario varieties.
Cacao pods are harvested by cutting them from the tree using a machete, or by knocking them off the tree using a stick. The beans with their surrounding pulp are removed from the pods and placed in piles or bins, allowing access to micro-organisms so fermentation of the pectin-containing material can begin. Yeasts produce ethanol, lactic acid bacteria produce lactic acid, and acetic acid bacteria produce acetic acid. The fermentation process, which takes up to seven days, also produces several flavor precursors, eventually resulting in the familiar chocolate taste.
It is important to harvest the pods when they are fully ripe, because if the pod is unripe, the beans will have a low cocoa butter content, or sugars in the white pulp will be insufficient for fermentation, resulting in a weak flavor. After fermentation, the beans must be quickly dried to prevent mold growth. Climate and weather permitting, this is done by spreading the beans out in the sun from five to seven days.
The dried beans are then transported to a chocolate manufacturing facility. The beans are cleaned (removing twigs, stones, and other debris), roasted, and graded. Next, the shell of each bean is removed to extract the nib. Finally, the nibs are ground and liquefied, resulting in pure chocolate in fluid form: chocolate liquor.The liquor can be further processed into two components: cocoa solids and cocoa butter.
Chocolate liquor is blended with the cocoa butter in varying quantities to make different types of chocolate or couverture. The basic blends of ingredients for the various types of chocolate (in order of highest quantity of cocoa liquor first), are:
Usually, an emulsifying agent, such as soy lecithin, is added, though a few manufacturers prefer to exclude this ingredient for purity reasons and to remain GMO-free, sometimes at the cost of a perfectly smooth texture. Some manufacturers are now using PGPR, an artificial emulsifier derived from castor oil that allows them to reduce the amount of cocoa butter while maintaining the same mouthfeel.
The texture is also heavily influenced by processing, specifically conching (see below). The more expensive chocolate tends to be processed longer and thus has a smoother texture and mouthfeel, regardless of whether emulsifying agents are added.
Different manufacturers develop their own "signature" blends based on the above formulas, but varying proportions of the different constituents are used. The finest, plain dark chocolate couverture contains at least 70% cocoa (both solids and butter), whereas milk chocolate usually contains up to 50%. High-quality white chocolate couverture contains only about 35% cocoa butter.
Producers of high-quality, small-batch chocolate argue that mass production produces bad-quality chocolate.Some mass-produced chocolate contains much less cocoa (as low as 7% in many cases), and fats other than cocoa butter. Vegetable oils and artificial vanilla flavor are often used in cheaper chocolate to mask poorly fermented and/or roasted beans.
In 2007, the Chocolate Manufacturers Association in the United States, whose members include Hershey, Nestlé, and Archer Daniels Midland, lobbied the Food and Drug Administration (FDA) to change the legal definition of chocolate to let them substitute partially hydrogenated vegetable oils for cocoa butter, in addition to using artificial sweeteners and milk substitutes.Currently, the FDA does not allow a product to be referred to as "chocolate" if the product contains any of these ingredients.
In the EU a product can be sold as chocolate if it contains up to 5% vegetable oil, and must be labeled as "family milk chocolate" rather than "milk chocolate" if it contains 20% milk.
According to Canadian Food and Drug Regulations,a "chocolate product" is a food product that is sourced from at least one "cocoa product" and contains at least one of the following: "chocolate, bittersweet chocolate, semi-sweet chocolate, dark chocolate, sweet chocolate, milk chocolate, or white chocolate". A "cocoa product" is defined as a food product that is sourced from cocoa beans and contains "cocoa nibs, cocoa liquor, cocoa mass, unsweetened chocolate, bitter chocolate, chocolate liquor, cocoa, low-fat cocoa, cocoa powder, or low-fat cocoa powder".
The penultimate process is called conching. A conche is a container filled with metal beads, which act as grinders. The refined and blended chocolate mass is kept in a liquid state by frictional heat. Chocolate before conching has an uneven and gritty texture. The conching process produces cocoa and sugar particles smaller than the tongue can detect, hence the smooth feel in the mouth. The length of the conching process determines the final smoothness and quality of the chocolate. High-quality chocolate is conched for about 72 hours, and lesser grades about four to six hours. After the process is complete, the chocolate mass is stored in tanks heated to about 45 to 50 °C (113 to 122 °F) until final processing.
The final process is called tempering. Uncontrolled crystallization of cocoa butter typically results in crystals of varying size, some or all large enough to be seen with the naked eye. This causes the surface of the chocolate to appear mottled and matte, and causes the chocolate to crumble rather than snap when broken.The uniform sheen and crisp bite of properly processed chocolate are the results of consistently small cocoa butter crystals produced by the tempering process.
The fats in cocoa butter can crystallize in six different forms (polymorphous crystallization).The primary purpose of tempering is to assure that only the best form is present. The six different crystal forms have different properties.
|I||17 °C (63 °F)||Soft, crumbly, melts too easily|
|II||21 °C (70 °F)||Soft, crumbly, melts too easily|
|III||26 °C (79 °F)||Firm, poor snap, melts too easily|
|IV||28 °C (82 °F)||Firm, good snap, melts too easily|
|V||34 °C (93 °F)||Glossy, firm, best snap, melts near body temperature (37 °C)|
|VI||36 °C (97 °F)||Hard, takes weeks to form|
As a solid piece of chocolate, the cocoa butter fat particles are in a crystalline rigid structure that gives the chocolate its solid appearance. Once heated, the crystals of the polymorphic cocoa butter can break apart from the rigid structure and allow the chocolate to obtain a more fluid consistency as the temperature increases – the melting process. When the heat is removed, the cocoa butter crystals become rigid again and come closer together, allowing the chocolate to solidify.
The temperature in which the crystals obtain enough energy to break apart from their rigid conformation would depend on the milk fat content in the chocolate and the shape of the fat molecules, as well as the form of the cocoa butterfat. Chocolate with a higher fat content will melt at a lower temperature.
Making chocolate considered "good" is about forming as many type V crystals as possible. This provides the best appearance and texture and creates the most stable crystals, so the texture and appearance will not degrade over time. To accomplish this, the temperature is carefully manipulated during the crystallization.
Generally, the chocolate is first heated to 45 °C (113 °F) to melt all six forms of crystals. Next, the chocolate is cooled to about 27 °C (81 °F), which will allow crystal types IV and V to form. At this temperature, the chocolate is agitated to create many small crystal "seeds" which will serve as nuclei to create small crystals in the chocolate. The chocolate is then heated to about 31 °C (88 °F) to eliminate any type IV crystals, leaving just type V. After this point, any excessive heating of the chocolate will destroy the temper and this process will have to be repeated. Other methods of chocolate tempering are used as well. The most common variant is introducing already tempered, solid "seed" chocolate. The temper of chocolate can be measured with a chocolate temper meter to ensure accuracy and consistency. A sample cup is filled with the chocolate and placed in the unit which then displays or prints the results.
Two classic ways of manually tempering chocolate are:
Chocolate tempering machines (or temperers) with computer controls can be used for producing consistently tempered chocolate. In particular, continuous tempering machines are used in large volume applications. Various methods and apparatuses for continuous flow tempering have been described by Aasted, Sollich and Buhler, three manufacturers of commercial chocolate equipment, with a focus now on energy efficiency. In general, molten chocolate coming in at 40–50 °C is cooled in heat exchangers to crystallization temperates of about 26–30 °C, passed through a tempering column consisting of spinning plates to induce shear, then warmed slightly to re-melt undesirable crystal formations.
Chocolate is very sensitive to temperature and humidity. Ideal storage temperatures are between 15 and 17 °C (59 and 63 °F), with a relative humidity of less than 50%. If refrigerated or frozen without containment, chocolate can absorb enough moisture to cause a whitish discoloration, the result of fat or sugar crystals rising to the surface. Various types of "blooming" effects can occur if chocolate is stored or served improperly.
Chocolate bloom is caused by storage temperature fluctuating or exceeding 24 °C (75 °F), while sugar bloom is caused by temperature below 15 °C (59 °F) or excess humidity. To distinguish between different types of bloom, one can rub the surface of the chocolate lightly, and if the bloom disappears, it is fat bloom. Moving chocolate between temperature extremes, can result in an oily texture. Although visually unappealing, chocolate suffering from bloom is safe for consumption and taste unaffected. Bloom can be reversed by retempering the chocolate or using it for any use that requires melting the chocolate.
Chocolate is generally stored away from other foods, as it can absorb different aromas. Ideally, chocolates are packed or wrapped, and placed in proper storage with the correct humidity and temperature. Additionally, chocolate is frequently stored in a dark place or protected from light by wrapping paper. The glossy shine, snap, aroma, texture, and taste of the chocolate can show the quality and if it was stored well.

A 100-gram serving of milk chocolate supplies 540 calories. It is 59% carbohydrates (52% as sugar and 3% as dietary fiber), 30% fat and 8% protein (table). Approximately 65% of the fat in milk chocolate is saturated, mainly palmitic acid and stearic acid, while the predominant unsaturated fat is oleic acid (table, see USDA reference for full report).
100-grams of milk chocolate is an excellent source (over 19% of the Daily Value, DV) of riboflavin, vitamin B12 and the dietary minerals, manganese, phosphorus and zinc. Chocolate is a good source (10–19% DV) of calcium, magnesium and iron.
Chocolate may be a factor for heartburn in some people because one of its constituents, theobromine, may affect the esophageal sphincter muscle in a way that permits stomach acids to enter the esophagus.Theobromine poisoning is an overdosage reaction to the bitter alkaloid, which happens more frequently in domestic animals than humans. However, daily intake of 50–100 g cocoa (0.8–1.5 g theobromine) by humans has been associated with sweating, trembling and severe headache. Chocolate contains alkaloids such as theobromine and phenethylamine, which have physiological effects in humans, but the presence of theobromine renders it toxic to some animals, such as dogs and cats.
Chocolate and cocoa contain moderate to high amounts of oxalate,which may increase someone's risk for kidney stones. During cultivation and production, chocolate may absorb the heavy metal lead from the environment, but the total amounts typically eaten are less than the tolerable daily limit for lead consumption, according to a World Health Organization report from 2010. However, reports from 2014 indicate that "chocolate might be a significant source" of lead ingestion for children if consumption is high, and "one 10 g cube of dark chocolate may contain as much as 20% of the daily lead oral limit."
A few studies have documented allergic reactions from chocolate in children.Other research has shown that dark chocolate can aggravate acne in men who are prone to it. Research has also shown that consuming dark chocolate does not substantially affect blood pressure. Chocolate and cocoa are under preliminary research to determine if consumption affects the risk of certain cardiovascular diseases or cognitive abilities.
A one-tablespoon (5 grams) serving of dry unsweetened cocoa powder has 12.1 mg of caffeine and a 25-g single serving of dark chocolate has 22.4 mg of caffeine. Although a single 7 oz. serving of coffee may contain 80–175 mg, studies have shown psychoactive effects in caffeine doses as low as 9 mg, and a dose as low as 12.5 mg was shown to have effects on cognitive performance.
Excessive consumption of large quantities of any energy-rich food, such as chocolate, without a corresponding increase in activity to expend the associated calories, can cause weight gain and possibly lead to obesity.Raw chocolate is high in cocoa butter, a fat which is removed during chocolate refining and then added back in varying proportions during the manufacturing process. Manufacturers may add other fats, sugars, and milk, all of which increase the caloric content of chocolate.
Cocoa contains certain phytochemicals. Cocoa solids are a source of flavonoidsand alkaloids, such as theobromine, phenethylamine, and caffeine.
Some manufacturers provide the percentage of chocolate in a finished chocolate confection as a label quoting percentage of "cocoa" or "cacao". This refers to the combined percentage of both cocoa solids and cocoa butter in the bar, not just the percentage of cocoa solids.The Belgian AMBAO certification mark indicates that no non-cocoa vegetable fats have been used in making the chocolate. A long-standing dispute between Britain and Belgium and France over British use of vegetable fats in chocolate ended in 2000 with the adoption of new standards which permitted the use of up to five percent vegetable fats in clearly labelled products. This British style of chocolate has sometimes been pejoratively referred to as "vegelate".
Chocolates that are organic or fair trade certified carry labels accordingly.
In the United States, some large chocolate manufacturers lobbied the federal government to permit confections containing cheaper hydrogenated vegetable oil in place of cocoa butter to be sold as "chocolate". In June 2007, as a response to consumer concern after the proposed change, the FDA reiterated "Cacao fat, as one of the signature characteristics of the product, will remain a principal component of standardized chocolate."
The chocolate industry is a steadily growing, $50 billion-a-year worldwide business centered on the sale and consumption of chocolate. It is prevalent throughout most of the world. Europe accounts for 45% of the world's chocolate revenue and the US$20 billion. Big Chocolate is the grouping of major international chocolate companies in Europe and the U.S. The U.S. companies, such as Mars and Hershey's alone, generate $13 billion a year in chocolate sales and account for two-thirds of U.S. production. Despite the expanding reach of the chocolate industry internationally, cocoa farmers and labourers in the Ivory Coast are unaware of the uses of the beans. The high cost of chocolate in the Ivory Coast also means that it is inaccessible to the majority of the population, who are unaware of what it tastes like.
Chocolate manufacturers produce a range of products from chocolate bars to fudge. Large manufacturers of chocolate products include Cadbury (the world's largest confectionery manufacturer), Ferrero, Guylian, The Hershey Company, Lindt & Sprüngli, Mars, Incorporated, Milka, Neuhaus and Suchard. Also, Brunberg in Porvoo, Finland is one of the most famous manufacturers of chocolate confectionery.
Guylian is best known for its chocolate sea shells; Cadbury for its Dairy Milk and Creme Egg. The Hershey Company, the largest chocolate manufacturer in North America, produces the Hershey Bar and Hershey's Kisses.Mars Incorporated, a large privately owned U.S. corporation, produces Mars Bar, Milky Way, M&M's, Twix, and Snickers. Lindt is known for its truffle balls and gold foil-wrapped Easter bunnies.
Food conglomerates Nestlé SA and Kraft Foods both have chocolate brands. Nestlé acquired Rowntree's in 1988 and now markets chocolates under their brand, including Smarties (a chocolate candy) and Kit Kat (a chocolate bar); Kraft Foods through its 1990 acquisition of Jacobs Suchard, now owns Milka and Suchard. In February 2010, Kraft also acquired British-based Cadbury;Fry's, Trebor Basset and the fair trade brand Green & Black's also belongs to the group.
The widespread use of children in cocoa production is controversial, not only for the concerns about child labor and exploitation, but also because up to 12,000 of the 200,000 children working in Côte d'Ivoire, the world's biggest producer of cocoa,may be victims of trafficking or slavery. Most attention on this subject has focused on West Africa, which collectively supplies 69 percent of the world's cocoa, and Côte d'Ivoire in particular, which supplies 35 percent of the world's cocoa. Thirty percent of children under age 15 in sub-Saharan Africa are child laborers, mostly in agricultural activities including cocoa farming. Major chocolate producers, such as Nestlé, buy cocoa at commodities exchanges where Ivorian cocoa is mixed with other cocoa.
In 2009, Salvation Army International Development (SAID) UK stated that 12,000 children have been trafficked on cocoa farms in the Ivory Coast of Africa, where half of the world's chocolate is made.SAID UK states that it is these child slaves who are likely to be working in "harsh and abusive" conditions for the production of chocolate, and an increasing number of health-food and anti-slavery organisations are highlighting and campaigning against the use of trafficking in the chocolate industry.
As of 2017, approximately 2.1 million children in Ghana and Côte d'Ivoire were involved in farming cocoa, carrying heavy loads, clearing forests, and being exposed to pesticides. According to Sona Ebai, the former secretary-general of the Alliance of Cocoa Producing Countries: "I think child labor cannot be just the responsibility of industry to solve. I think it's the proverbial all-hands-on-deck: government, civil society, the private sector. And there, you need leadership." Reported in 2018, a 3-year pilot program – conducted by Nestlé with 26,000 farmers mostly located in Côte d'Ivoire – observed a 51% decrease in the number of children doing hazardous jobs in cocoa farming. The US Department of Labor formed the Child Labor Cocoa Coordinating Group as a public-private partnership with the governments of Ghana and Côte d'Ivoire to address child labor practices in the cocoa industry. The International Cocoa Initiative involving major cocoa manufacturers established the Child Labor Monitoring and Remediation System intended to monitor thousands of farms in Ghana and Côte d'Ivoire for child labor conditions, but the program reached less than 20% of the child laborers. Despite these efforts, goals to reduce child labor in West Africa by 70% before 2020 are frustrated by persistent poverty, absence of schools, expansion of cocoa farmland, and increased demand for cocoa.
In April 2018, the Cocoa Barometer report stated: "Not a single company or government is anywhere near reaching the sector-wide objective of the elimination of child labor, and not even near their commitments of a 70% reduction of child labor by 2020".
In the 2000s, some chocolate producers began to engage in fair trade initiatives, to address concerns about the marginalization of cocoa laborers in developing countries. Traditionally, Africa and other developing countries received low prices for their exported commodities such as cocoa, which caused poverty to abound. Fairtrade seeks to establish a system of direct trade from developing countries to counteract this unfair system.One solution for fair labor practices is for farmers to become part of an Agricultural cooperative. Cooperatives pay farmers a fair price for their cocoa so farmers have enough money for food, clothes, and school fees. One of the main tenets of fair trade is that farmers receive a fair price, but this does not mean that the larger amount of money paid for fair trade cocoa goes directly to the farmers. The effectiveness of fair trade has been questioned. In a 2014 article, The Economist stated that workers on fair trade farms have a lower standard of living than on similar farms outside the fair trade system.
Chocolate is sold in chocolate bars, which come in dark chocolate, milk chocolate and white chocolate varieties. Some bars that are mostly chocolate have other ingredients blended into the chocolate, such as nuts, raisins, or crisped rice. Chocolate is used as an ingredient in a huge variety of bars, which typically contain various confectionary ingredients (e.g., nougat, wafers, caramel, nuts, etc.) which are coated in chocolate.
Chocolate is used as a flavouring product in many desserts, such as chocolate cakes, chocolate brownies, chocolate mousse and chocolate chip cookies. Numerous types of candy and snacks contain chocolate, either as a filling (e.g., M&M's) or as a coating (e.g., chocolate-coated raisins or chocolate-coated peanuts).
Some non-alcoholic beverages contain chocolate, such as chocolate milk, hot chocolate and chocolate milkshakes. Some alcoholic liqueurs are flavoured with chocolate, such as chocolate liqueur and creme de cacao. Chocolate is a popular flavour of ice cream and pudding, and chocolate sauce is a commonly added as a topping on ice cream sundaes. The caffè mocha is an espresso beverage containing chocolate.
Dessert is a course that concludes a meal. The course usually consists of sweet foods, such as confections, and possibly a beverage such as dessert wine or liqueur; however, in the United States it may include coffee, cheeses, nuts, or other savory items regarded as a separate course elsewhere. In some parts of the world, such as much of central and western Africa, and most parts of China, there is no tradition of a dessert course to conclude a meal.
Nutella is a brand of sweetened hazelnut cocoa spread. Nutella is manufactured by the Italian company Ferrero and was first introduced in 1964, although its first iteration dates to 1963.
The cocoa bean or simply cocoa, which is also called the cacao bean or cacao , is the dried and fully fermented seed of Theobroma cacao, from which cocoa solids and cocoa butter can be extracted. Cocoa beans are the basis of chocolate, and Mesoamerican foods including tejate, an indigenous Mexican drink that also includes maize.
Hot chocolate, also known as drinking chocolate, cocoa, and as chocolate tea in Nigeria, is a heated drink consisting of shaved chocolate, melted chocolate or cocoa powder, heated milk or water, and usually a sweetener. Hot chocolate may be topped with whipped cream or marshmallows. Hot chocolate made with melted chocolate is sometimes called drinking chocolate, characterized by less sweetness and a thicker consistency.
A chocoholic is a person who craves or compulsively consumes chocolate. The word "chocoholic" was first used in 1968, according to Merriam-Webster. It is a portmanteau of "chocolate" and "alcoholic".The term is used loosely or humorously to describe a person who is inordinately fond of chocolate; however, there is medical evidence to support the existence of actual addiction to chocolate. Psychoactive constituents of chocolate that trigger a ‘feel-good’ reaction for the consumer include triptophan and phenylethylamine, which may contribute to cravings and addiction-like responses, particularly in people with specific genetic alleles. The quantity of sugar used in chocolate confections also impacts the psychoactive effects of chocolate. Although the concept of a chocolate addiction is still controversial in the medical literature, chocolate is considered to have effects on mood and chocolate confectioneries almost always top the list of foods people say they crave. The craving can be so strong in some cases that chocoholics may experience withdrawal symptoms if the craving is not fulfilled.
Cocoa butter, also called theobroma oil, is a pale-yellow, edible fat extracted from the cocoa bean. It is used to make chocolate, as well as some ointments, toiletries, and pharmaceuticals. Cocoa butter has a cocoa flavor and aroma. Its melting point is just below human body temperature.
Coenraad Johannes van Houten was a Dutch chemist and chocolate maker known for the treatment of cocoa mass with alkaline salts to remove the bitter taste and make cocoa solids more water-soluble; the resulting product is still called "Dutch process chocolate". He is also credited with introducing a method for pressing the fat from roasted cocoa beans, though this was in fact his father, Casparus van Houten's invention.
White chocolate is a chocolate confection made from cocoa butter, sugar and milk solids. White chocolate does not contain cocoa solids, which are found in other types of chocolate. It is characterized by a pale ivory color. The melting point of cocoa butter, the only cocoa bean component of white chocolate, is high enough to keep white chocolate solid at room temperature, as with milk chocolate and dark chocolate.
Scharffen Berger Chocolate is a line of chocolate produced by Artisan Confections Company, a subsidiary of The Hershey Company. Acquired by Hershey in 2005, it was formerly Scharffen Berger Chocolate Maker, an independent Berkeley, California-based chocolate maker, founded in 1996 by sparkling wine maker John Scharffenberger and physician Robert Steinberg.
Cocoa may refer to:
Raw chocolate is chocolate produced primarily from unroasted cocoa beans. Dairy products are often not added to raw chocolate and alternative or alcohol sugars, such as coconut sugar, coconut nectar, xylitol, agave nectar, maple syrup, and stevia, are used. Raw chocolate is naturally gluten-free and generally considered vegan.
Couverture chocolate is a very high-quality chocolate that contains a higher percentage of cocoa butter (32–39%) than baking or eating chocolate. This additional cocoa butter, combined with proper tempering, gives the chocolate more sheen, a firmer "snap" when broken, and a creamy mellow flavor.
Polyglycerol polyricinoleate (PGPR), E476, is an emulsifier made from glycerol and fatty acids. In chocolate, compound chocolate and similar coatings, PGPR is mainly used with another substance like lecithin to reduce viscosity. It is used at low levels, and works by decreasing the friction between the solid particles in molten chocolate, reducing the yield stress so that it flows more easily, approaching the behaviour of a Newtonian fluid. It can also be used as an emulsifier in spreads and in salad dressings, or to improve the texture of baked goods. It is made up of a short chain of glycerol molecules connected by ether bonds, with ricinoleic acid side chains connected by ester bonds.
Chocolate is a range of foods derived from cocoa (cacao), mixed with fat and finely powdered sugar to produce a solid confectionery. There are several types of chocolate, classified according to the proportion of cocoa used in a particular formulation.
The history of chocolate began in Mesoamerica. Fermented beverages made from chocolate date back to 450 BC. The Aztecs believed that cacao seeds were the gift of Quetzalcoatl, the god of wisdom, and the seeds once had so much value that they were used as a form of currency. Originally prepared only as a drink, chocolate was served as a bitter liquid, mixed with spices or corn puree. It was believed to be an aphrodisiac and to give the drinker strength. Today, such drinks are also known as "Chilate" and are made by locals in the South of Mexico. After its arrival to Europe in the sixteenth century, sugar was added to it and it became popular throughout society, first among the ruling classes and then among the common people. In the 20th century, chocolate was considered essential in the rations of United States soldiers during war.
Dry cocoa solids are the components of cocoa beans remaining after cocoa butter, the fat component, is extracted from chocolate liquor, roasted cocoa beans that have been ground into a liquid state. Cocoa butter is 50% to 57% of the weight of cocoa beans and gives chocolate its characteristic melting properties. Cocoa powder is the powdered form of the solids sold as an end product.
The following outline is provided as an overview of and topical guide to chocolate:
The health effects of chocolate are the possible positive and negative effects on health of eating chocolate.
Dark chocolate is a form of chocolate containing cocoa solids, cocoa butter, without the milk and sugar found in milk chocolate. Government and industry standards of what products may be labeled "dark chocolate" vary by country and market.
Ruby chocolate is a variety of chocolate introduced in 2017 by Barry Callebaut, a Belgian–Swiss cocoa company. The variety has been in development since 2004 and in 2015, the product was patented by Dumarche et al. credited as inventors and Barry Callebaut as assignee under patent number US 9107430, 2015. It was unveiled at a private event in Shanghai on 5 September, 2017. It is marketed as the "fourth" type of chocolate alongside dark, milk, and white chocolate varieties and is notable for its natural pink colour.
For a decade and a half, the big chocolate makers have promised to end child labor in their industry – and have spent tens of millions of dollars in the effort. But as of the latest estimate, 2.1 million West African children still do the dangerous and physically taxing work of harvesting cocoa. What will it take to fix the problem?
