Batch solvent extraction of caffeine from MCBC2

Caffeine is a naturally occurring substance found in cocoa seeds. The aim of this research is to extract caffeine from Malaysian Cocoa Board Clone (MCBC) 2, and to investigate the effect of sample particle size, solvent/feed ratio, and extraction time on the yield of caffeine. The sample was prepare...
