Batch extraction of caffeine from cocoa MCBC 1

Caffeine is naturally occurring substances found in the leaves seeds of fruits of a group of compounds known as methylxanthines. The most commonly known source of caffeine is coffee and cocoa seeds. However, cocoa seeds have received limited attention as a source for caffeine since it widely used as...
