Some days ago, before buying a chocolate I read the ingredients and saw that it contains a natural emulsifier. A Google search didn't reveal anything about of what the emulsion formed is, do you have any idea?
The general composition of chocolate:
The main components in milk chocolate is cocoa butter, sugar, and milk powder.
Then, a concrete example:
Hershey’s chocolate is made of sugar, chocolate, cocoa butter, cocoa processed with alkali, milk fat, lactose (milk), soy lecithin, PGPR (emulsifier), vanillin, artificial flavor, and milk.

I continue wondering what the emulsion is formed by.
