Introduction
My chemistry of dot dot dot is chocolate. I chose chocolate because it’s used everyday for multiply things. Chocolate is a processed food made from the seed of the tropical Theobroma Cacao tree. The earliest evidence of chocolate is 1100 B.C. by the Mesoamerican people. The chocolate beverage was so bitter it was used in beverages known as xocolatl or “bitter water”. It was first introduced to Europe, during the 16th century, by a Spanish conquistador, named Hernan Cortes. In 1867, a swiss candle maker, named Daniel Peter started to experiment with chocolate as an ingredient. Milk chocolate was created in 1875.

Chemistry's Role
Cocoa butter is made from whole cacao beans, which are fermented, then roasted, and finally separated from their hull’s. This is made into chocolate liquor which is pressed to separate cocoa butter from cocoa solids.
Sugar is also a very important part of chocolate. The sugar that is used in our foods is pulled of a plant called sugarcane. The sugarcane gets juiced, then crystallized to make sugar.
My final product would be chocolate which is a good product, that uses many forms of chemistry to make this fabulous treat.
Background Research
Chocolate is made from cacao beans. Which are fermented, then dried, then cleaned, and finally roasted. The shells are removed to produce cacao nibs. The nibs are grounded into cocoa mass. The cocoa mass gets liquefied to form chocolate liquor. Which is finally process into cocoa solids and cocoa butter. To make the classic milk chocolate bar, you mix cocoa butter, sugar, and milk powder or condensed milk.
