摘要：

A commercially available lipase (A. niger, APF-12) was employed to hydrolyze an emulsified butteroil substrate. HPLC analyses of the reaction products indicated that short chain fatty acid residues (e.g., butyric acid) were preferably hydrolyzed at pH 5 whereas the overall rate of hydrolysis for all major fatty acids showed a pH optimum between 6 and 7. This indicated the possibility of directing the selectivity of lipolysis in butteroil to enhance production of short-chain fatty acids associated with flavor development. The optimal temperature was ca. 35-degrees-C. Different cations also affected rate of hydrolysis.
