Abstract
|
|
|
|
To establish optimal conditions for esterification by Candida cylindracea, lipase reactions were performed simultaneously, separately, or individually in the varying initial rates of 0.014-0.060μ㏖e free fatty acids consumed min^-1 g^-1. The reactants which were conditioned at a_w of 0.12 gave the highest initial rate of esterifying 0.060μ㏖e free fatty acids consumed min^-1 g^-1. These results suggest that the esterifying activity of lipase in an organic system depends on the transfer of available water within the reaction system.
