No, but the cocoa liquor and cocoa powder parts of the cocoa bean do both contain caffeine.
White chocolate contains only cocoa butter, not cocoa solids. Caffeine is only in the solids so white chocolate does not have any.
Great news - Yes! Cocoa butter does not contain dairy.
No it does not contain Nickel, nickel is a metal and butter is made from milk solids (fat).
One nut that contains caffeine is the Kola nut, which is used to make chocolate.
Very small amounts.
Yes, chocolate chips do have caffeine in them, which stems from the natural cocoa bean.
Presumably yes, since they contain either dark chocolate or cocoa powder, which have caffeine.
they say that chocolate containing caffeine is a myth
Not usually, no.
Cocoa beans are a type of fully fermented and dried fatty bean in which is known to be used to produce cocoa butter and other cocoa solids. Cocoa beans contain about 40 seeds and mucilaginous pulp.
No it does not. There was a science project done on it, and even IF it did it is not enough to effect you.
20 mg / oz - http://coffeetea.about.com/library/blcaffeine.htm While the above referenced content of caffeine may be common in commercially processed chocolate, it is not always so. The caffeine content of chocolate has been the subject of much debate -- and conflicting research from the scientific community. Some data sugests that there is caffeine content in the cocoa bean, though the International Cocoa Organization states that the caffeine content is very low. Other data suggests that there is no caffeine in cocoa, and that any caffeine present has been added by manufacturers. It's also interesting to note that some data suggests that the caffeine only resides in the fiber and husk that surround the cocoa bean. In that case, if the beans are properly cleaned, there should be virtually NO caffeine in the resulting chocolate product. - http://www.thefivereasons.com/
