The Correlation between Lipase Activity and the Production of Fatty Acids of PBC Cocoa Clone

A study was carried out to determine the correlation between lipase activity in cocoa beans and the presence of free fatty acids which could affect the aroma and flavour of cocoa. Lipase activity fell from 0.46 to 0.15 ~mol/min/mg protein during six days of fermentation. Changes in the pH from 6.6...
