Chocolate makers must cook the beans, and then crush them to make the cocoa butter and the chocolate liquor come out of them.

In chocolate, fermentation is the process that creates aromas, bold flavor and rich color. There are two stages: alcohol and acetic fermentation. First, natural yeast converts the sugars in the cocoa pulp into alcohol. Then bacteria oxidize the alcohol into acetic acid.
What kind of mixture is chocolate?
homogeneous mixture. Chocolate is made up of cocoa powder, cocoa butter, sweetener, and some other substances that are mixed with each other in an indefinite ratio. So, chocolate is not a pure substance but is a homogenous mixture (it has a uniform composition).
Why does chocolate melt science?
The melting point for fat molecules in chocolate is about 36°C, which is very close to our body temperature of 37°C. Thus, at temperature below 36°C (like your hand, which is around 27-32°C) chocolate still stays solid. However, above 36°C (like inside your mouth) the chocolate will melt.
What are the properties of chocolate?
Chocolate contains theobromine, which, like caffeine, stimulates the central nervous system. Chocolate is able to stimulate the hormone serotonin, providing a feeling of well-being. In moderation, the consumption of chocolate increases the feeling of satiety.
What happens to the molecules in chocolate when it melts?
The arrangement of the different types of molecules within chocolate impacts the texture, hardness, and shine of chocolate. When chocolate is heated, thermal energy disrupts its ordered crystalline structure, causing it to melt into a liquid.
Why can humans digest chocolate?
Chocolate is derived from the roasted seeds of the plant Theobroma cacao, and the main toxic components are the methylxanthine alkaloids theobromine and caffeine. Humans can easily digest and excrete methylxanthines, the half life of theobromine being 2-3 hours.
