Re: What is the chemical formula for chocolate?

Not an easy answer by any stretch of the imagination... Chocolate, like many foods, is made up of a mix of other ingredients like sugar, cocoa, vanilla, emulsifiers, etc. I suppose it really depends on the quality of the chocolate you are interested in. You will also find a lot of information on the label of the chocolate you like to eat. I did find a web link that might help:

If you are really asking about cocoa, the answer still is not all that different. Cocoa is an agricultural product, harvested from trees and contains a wide variety of different 'chemical' components. Cocoa contains a fair amount of fat (cocoa butter), theobromine (the stuff that is so bad for dogs), proteins, antioxidants, etc. So, again, I am not really answering your question but I am not sure how to.

Here is one more link I found that might be helpful: http://www.acri-cocoa.org/

Quite a bit of information is available on the Internet if you need more help. Good luck!
