Enzymatic activity of proteases and its isoenzymes in fermentation process in cultivars of cocoa (Theobroma cacao L.) produced in southern Bahia, Brazil

Abstract The fermentation of cocoa seeds envolves microbial processes and the action of enzymes. To identify the possible differences in the cocoa fermentation process, with regards to proteolysis, this study has the objective of determining protease activity (under predetermined conditions) and its isoenzymes in two cocoa cultivars (PH-16 and HRT-1188) in different cocoa fermentation times, in addition to establishing the microbial load (molds and yeasts and aerobic mesophilic). Protease and its isoenzymes were extracted and partially purified and the enzymatic activities determined by spectr...
