ABSTRACT

The Sul 1 cacao (Theobroma cacao) genotype has become more popular among cocoa producers due to its resistance toward vascular streak dieback, a devastating dieback disease in cacao plants. Sul 1 cocoa beans were subjected to prolonged fermentation of 10 days (240 h). Changes in the composition of methylxanthines, polyphenols, and volatiles and sensory profiles of the cocoa beans as affected by fermentation were analyzed. The first 48 h of fermentation significantly determined the composition of the methylxanthines and polyphenols in the cocoa beans. A prolonged fermentation (>96 h) period did not further reduce the contents of methylxanthines and polyphenols in the cocoa beans. Important volatiles characteristic of the cocoa/chocolate flavor were mostly developed after 48 h of fermentation. The fermentation for 72 h retained considerable amounts of methylxanthines and polyphenols in the beans while producing cocoa mass with good sensory profiles.
