INTRODUCTION
Chocolate comprises a number of raw and processed foods 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, with its earliest documented use around 1100 BC. The majority of the Mesoamerican peoples made chocolate beverages, including the Aztecs and the Maya, who made it into a beverage known as xocolātl, a Nahuatl word meaning "bitter water". The seeds of the cacao tree have an intense bitter taste, and must be fermented to develop the flavor. Chocolate has become one of the most popular food types and flavors in the world. Gifts of chocolate molded 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 hearts on Valentine's Day. Chocolate is also used in cold and hot beverages, to produce chocolate milk and hot chocolate. The world's top producer of cacao beans is Africa, where recent controversy has focused on the use of child labor in cocoa production.
After fermentation, the beans are dried, cleaned, and 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 molded 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 (and thus does not qualify to be considered true chocolate).
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. Scientists claim that chocolate, eaten in moderation, can lower blood pressure. Dark chocolate has recently been promoted for its health benefits, including a substantial amount of antioxidants that reduce the formation of free radicals, although current scientific evidence is against health improvements by dietary antioxidants. The presence of theobromine renders it toxic to some animals, especially dogs and cats.

Chocolate is a key ingredient in many foods such as milk shakes, candy bars, cookies and cereals. It is ranked as one of the most favourite flavours in North America and Europe (Swift, 1998). Despite its popularity, most people do not know the unique origins of this popular treat. Chocolate is a product that requires complex procedures to produce. The process involves harvesting coca, refining coca to cocoa beans, and shipping the cocoa beans to the manufacturing factory for cleaning, coaching and grinding. These cocoa beans will then be imported or exported to other countries and be transformed into different type of chocolate products (Allen, 1994).

Important inventions
Dutchman Conraad Van Houten invented how to separate cocoa butter from cocoa mass in 1828.
First chocolate bars were probably produced by english company Fry´s from Bristol in 1847.
Swiss Daniel Peter invented milk chocolate in 1875.
Swiss Rodolphe Lindt invented conching process in 1879.
Séchaud Fils from Montreaux in Switzerland produced first filled chocolate in 1913.
First white chocolate was manufactured by swiss company Nestlé in 1930´s. It was called Galak.
ETYMOLOGY AND HISTORY
Etymology
The word "chocolate" entered the English language from Spanish. How the word came into Spanish is less certain, and there are multiple competing explanations. 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 Wichmann 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".
History
The word "chocolate" originates in Mexico's Aztec cuisine, derived from the Nahuatl word xocolatl.
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 has been used as a drink for nearly all of its history. The earliest record of using chocolate dates back before the Olmec. In November 2007, archaeologists reported finding evidence of the oldest known cultivation and use of cacao at a site in Puerto Escondido, Honduras, dating from about 1100 to 1400 BC. The residues found and the kind of vessel they were found in indicate that 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. The Maya civilization grew cacao trees in their backyard, and used the cacao seeds it produced to make a frothy, bitter drink. Documents in Maya hieroglyphs stated that chocolate was used for ceremonial purposes, in addition to everyday life. The chocolate residue found in an early ancient Maya pot in Río Azul, Guatemala, suggests that Maya were drinking chocolate around 400 AD. In the New World, chocolate was consumed in a bitter, spicy drink called xocoatl, and was often flavored with vanilla, chili pepper, and achiote (known today as annatto).Xocoatl was believed to fight fatigue, a belief that is probably attributable to the theobromine content. Chocolate was also an important luxury good throughout pre-Columbian Mesoamerica, and cacao beans were often used as currency. For example, the Aztecs used a system in which one turkey cost one hundred cacao beans and one fresh avocado was worth three beans. South American and European cultures have used cocoa to treat diarrhea for hundreds of years. 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".
Until the 16th century, no European had ever heard of the popular drink from the Central and South American peoples. It was not until the Spanish conquest of the Aztecs that chocolate could be imported to Europe. In Spain it quickly became a court favorite. In a century it had spread and become popular throughout the European continent To keep up with the high demand for this new drink, Spanish armies began enslaving Mesoamericans to produce cacao. Even with cacao harvesting becoming a regular business, only royalty and the well-connected could afford to drink this expensive import. Before long, the Spanish began growing cacao beans on plantations, and using an African workforce to help manage them. The situation was different in England. Put simply, anyone with money could buy it. The first chocolate house opened in London in 1657. In 1689, noted physician and collector Hans Sloane developed a milk chocolate drink in Jamaica which was initially used by apothecaries, but later sold to the Cadbury brothers in 1897.
