Batch extraction of 1,3,7-trymethylxanthine from KKM22 cocoa seeds

1,3,7- trymethylxanthine (caffeine) is a naturally occurring substance found in cocoa seeds.The purpose of this research is to extract caffeine from Klon Koko Malaysia (KKM)22, to investigate the effect of particle size,solvent/feed ratio and extraction time,and also to determine the kinetic model f...
