What Is Chocolate?
Chocolate is a raw or processed food produced from the seed of the tropical Theobroma cacao tree. Cacao has been cultivated for at least three millennia in Mexico, Central and South America. Its earliest documented use is around 1100 BC. The majority of the Mesoamerican people made chocolate beverages, including the Aztecs, who made it into a beverage known as xocolﾄ》l, a Nahuatl word meaning "bitter water". The seeds of the cacao tree have an intense bitter taste, and must be fermented to develop the flavour. After fermentation, the beans are dried, then cleaned, and then roasted, and the shell is removed to produce cacao nibs. The nibs are then ground to cocoa mass, pure chocolate in rough form. Because this cocoa mass usually is liquefied then moulded with or without other ingredients, it is called chocolate liquor. The liquor also may be processed into two components: cocoa solids and cocoa butter. Unsweetened baking chocolate (bitter chocolate) contains primarily cocoa solids and cocoa butter in varying proportions. Much of the chocolate consumed today is in the form of sweet chocolate, combining cocoa solids, cocoa butter or other fat, 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. Cocoa solids contain alkaloids such as theobromine and phenethylamine, which have physiological effects on the body. It has been linked to serotonin levels in the brain. Some research found that chocolate, eaten in moderation, can lower blood pressure. The presence of theobromine renders chocolate toxic to some animals, especially dogs and cats. Chocolate has become one of the most popular food types and flavours in the world. Gifts of chocolate moulded into different shapes have become traditional on certain holidays: chocolate bunnies and eggs are popular on Easter, chocolate coins on Hanukkah, Santa Claus and other holiday symbols on Christmas, and chocolate hearts or chocolate in heart-shaped boxes on Valentine's Day. Chocolate is also used in cold and hot beverages, to produce chocolate milk and hot chocolate.
Theobroma cacao, native to Mexico, Central and South America, has been cultivated for at least three millennia in that region. Cocoa mass was used originally in Mesoamerica both as a beverage and as an ingredient in foods. Chocolate played a special role in both Maya and Aztec royal and religious events. Priests presented cacao seeds as offerings to the gods and served chocolate drinks during sacred ceremonies. All of the areas that were conquered by the Aztecs that grew cacao beans were ordered to pay them as a tax, or as the Aztecs called it, a "tribute". The Europeans sweetened and fattened it by adding refined sugar and milk, two ingredients unknown to the Mexicans. By contrast, the Europeans never infused it into their general diet, but have compartmentalized its use to sweets and desserts. In the 19th century, Briton John Cadbury developed an emulsification process to make solid chocolate creating the modern chocolate bar. Although cocoa is originally from the Americas, today Western Africa produces almost two-thirds of the world's cocoa, with C么te d'Ivoire growing almost half of it. http://en.wikipedia.org/wiki/Chocolate
Chocolate History
The history of chocolate begins in Mesoamerica. Chocolate, the fermented, roasted, and ground beans of the Theobroma cacao, can be traced to the Mokaya and other pre-Olmec people, with evidence of cacao beverages dating back to 1900 BCE. Chocolate played a special role in both Maya and Aztec royal and religious events. Priests presented cacao seeds as offerings to the gods and served chocolate drinks during sacred ceremonies. All of the areas that were conquered by the Aztecs that grew cacao beans were ordered to pay them as a tax, or as the Aztecs called it, a "tribute". The Europeans sweetened and fattened it by adding refined sugar and milk, two ingredients unknown to the Mexicans. By contrast, they never infused it into their general diet, but have compartmentalized its use to sweets and desserts. In the 19th century, Briton John Cadbury developed an emulsification process to make solid chocolate creating the modern chocolate bar. For hundreds of years, the chocolate making process remained unchanged. When the Industrial Revolution arrived, many changes occurred that brought the hard, sweet candy to life. In the 18th century, mechanical mills were created that squeezed out cocoa butter, which in turn helped to create hard, durable chocolate. But, it was not until the arrival of the Industrial Revolution that these
mills were put to bigger use. Not long after the revolution cooled down, companies began advertising this new invention to sell many of the chocolate treats seen today. When new machines were produced, people began experiencing and consuming chocolate worldwide. Although cocoa is originally from the Americas, today Western Africa produces almost two-thirds of the world's cocoa, with Cﾃｴte d'Ivoire growing almost half of it. The origins of the word "chocolate" probably comes from the Classical Nahuatl word xocolﾄ》l (meaning "bitter water"), and entered the English language from Spanish. How the word "chocolate" came into Spanish is not certain. Perhaps the most cited explanation is that "chocolate" comes from Nahuatl, the language of the Aztecs, from the word "chocolatl", which many sources derived from the Nahuatl word "xocolatl" made up from the words "xococ" meaning sour or bitter, and "atl" meaning water or drink. However, as William Bright noted the word "chocolatl" doesn't occur in central Mexican colonial sources making this an unlikely derivation. Santamaria gives a derivation from the Yucatec Maya word "chokol" meaning hot, and the Nahuatl "atl" meaning water. More recently Dakin and Wichman derive it from another Nahuatl term, "chicolatl" from Eastern Nahuatl meaning "beaten drink". They derive this term from the word for the frothing stick, "chicoli". The word xocoatl means beverage of maize. The words "cacaua atl" mean drink of cacao. The word "xocolatl" does not appear in Molina's dictionary. http://en.wikipedia.org/wiki/History_of_chocolate
Different Types Of Chocolate
Several types of chocolate can be distinguished. Pure, unsweetened chocolate contains primarily cocoa solids and cocoa butter in varying proportions. Much of the chocolate consumed today is in the form of sweet chocolate, combining chocolate with sugar. Milk chocolate is sweet chocolate that additionally contains milk powder or condensed milk. In the U.K. 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" contains cocoa butter, sugar, and milk, but no cocoa solids. Chocolate contains alkaloids such as theobromine and phenethylamine, which have some physiological effects in humans, but the presence of theobromine renders it toxic to some animals, such as dogs and cats. It has been linked to serotonin levels in the brain. Dark chocolate has been promoted for unproven health benefits, as it seems to possess substantial amount of antioxidants that reduce the formation of free radicals.
White chocolate is formed from a mixture of sugar, cocoa butter and milk solids. Although its texture is similar to milk and dark chocolate, it does not contain any cocoa solids. Because of this, many countries do not consider white chocolate as chocolate at all. Although first introduced by Hebert Candies in 1955, Mars, Incorporated was the first to produce white chocolate within the United States. Because it does not contain any cocoa solids, white chocolate does not contain any theobromine, meaning it can be consumed by animals. It is usually not used for cooking. Dark chocolate is produced by adding fat and sugar to the cacao mixture. The U.S. Food and Drug Administration call this "sweet chocolate", and requires a 15% concentration of chocolate liquor. European rules specify a minimum of 35% cocoa solids. Dark chocolate, with its high cocoa content, is a rich source of epicatechin and gallic acid, which are thought to possess cardio protective properties. Dark chocolate has also been said to reduce the possibility of a heart attack when consumed regularly in small amounts. Semisweet chocolate is a dark chocolate with a low sugar content. Bittersweet chocolate is chocolate liquor to which some sugar (typically a third), more cocoa butter, vanilla and sometimes lecithin have been added. It has less sugar and more liquor than semisweet chocolate, but the two are interchangeable in baking. 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 flavour. Raw chocolate, often referred to as raw cacao, is always dark and a minimum of 75% cacao. Because the act of processing results in the loss of certain vitamins and minerals (such as magnesium), some consider raw cacao to be a more nutritious form of chocolate. Some people who purchase chocolate off the store shelf can be disappointed when they see whitish spots on the dark chocolate part. This is called chocolate bloom and is not an indication of chocolate gone bad. Instead, this is just an indication that sugar and/or fat has separated due to poor storage. http://en.wikipedia.org/wiki/Chocolate
Where Is Chocolate Produced?
Roughly two-thirds of the entire world's cocoa is produced in West Africa, with 43% sourced from C么te d'Ivoire, where child labour is a common practice to obtain the product. According to the World Cocoa Foundation, some 50 million people around the world depend on cocoa as a source of
livelihood. In the UK, most chocolatiers purchase their chocolate from them, to melt, mould and package to their own design. Despite some disagreement in the EU about the definition,[clarification needed] chocolate is any product made primarily of cocoa solids and cocoa butter. Production costs can be decreased by reducing cocoa solid 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 genome of the cacao tree may allow yields to be improved. There are two main jobs associated with creating chocolate candy, 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.). http://en.wikipedia.org/wiki/Chocolate
Chocolate Processing
Cacao pods are harvested by cutting the pods 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 microorganisms so that fermentation of the pectincontaining material can begin. Yeast 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 flavour 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 low cocoa butter content, or there will be insufficient sugars in the white pulp for fermentation, resulting in a weak flavour. After fermentation, the beans must be quickly dried to prevent mould 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. http://en.wikipedia.org/wiki/Chocolate
Chocolate Brings Health Benefits?
Even though chocolate is regularly eaten for pleasure, there are potentially many health effects, both negative and positive. Cocoa or dark chocolate may positively affect the circulatory system. Other possible effects under basic research include anticancer, brain stimulator, cough preventer and antidiarrhoeal activities. An aphrodisiac effect is yet unproven[citation needed]. According to research, limited amounts of dark chocolate appear to help prevent heart disease. The oxidation of LDL cholesterol is considered a major factor in the promotion of coronary disease. When this waxy substance oxidizes, it tends to stick to artery walls, increasing the risk of a heart attack or stroke. Research has shown the polyphenols in chocolate inhibit oxidation of LDL cholesterol. On the other hand, the unconstrained consumption of large quantities of any energy-rich food, such as chocolate, without a corresponding increase in activity, is thought to increase the risk of obesity. Raw chocolate is high in cocoa butter, a fat which is removed during chocolate refining, then added back in in varying proportions during the manufacturing process. Manufacturers may add other fats, sugars, and milk as well, all of which increase the caloric content of chocolate. Chocolate absorbs lead from the environment during production, and there is a slight concern of mild lead poisoning for some types of chocolate. The average lead concentration of cocoa beans was a very low ≤ 0.5 ng/g, one of the lowest reported values for a natural food. Lead concentration of chocolate was as high as 70 ng/g for chocolate products and 230 ng/g for manufactured cocoa. 200,000 ng is the WHO tolerable daily limit for lead consumption. Additionally, chocolate is toxic to many animals because of insufficient capacity to metabolize theobromine. A BBC report indicated that melting chocolate in one's mouth produced an increase in brain activity and heart rate that was more intense than that associated with passionate kissing, and also lasted four times as long after the activity had ended. In later research, chocolate has been linked with multiple health benefits and liabilities. Research on elderly people showed chocolate might cause osteoporosis. However, more research has shown that it will boost cognitive abilities. Further, dark chocolate and cocoa butter have been linked with multiple positive effects. Scientific evidence has suggested dark chocolate can help reduce the risk of cardiovascular problems and also reduce blood pressure in both overweight and normal adults. Finally, studies have shown dark chocolate as part of a low-fat diet can lower cholesterol levels in adults.
In August 2011, Cambridge research published in the British Medical Journal: Eating high levels of chocolate could be associated with a significant reduction in the risk of certain cardiovascular disorders. http://en.wikipedia.org/wiki/Chocolate
