摘要:
A method for producing symmetric triglycerides, which comprises the steps of reacting a medium chain fatty acid triglyceride with a long chain fatty acid triglyceride in the presence of an enzyme or a chemical catalyst to conduct random transesterification reaction and thereby to obtain a reaction product containing a triglyceride composed of a medium chain fatty acid and a long chain fatty acid as the constituting fatty acids in the step of the first reaction; transesterifying the reaction product with an alcohol monoester of the medium chain fatty acid in the presence of an sn-1,3-position specific enzyme in the step of the second reaction and then taking the alcohol monoester of the medium chain fatty acid and the alcohol monoester of the long chain fatty acid from the reaction product obtained in the step of the second reaction to obtain the symmetric triglyceride composed of the medium chain fatty acids at the sn-1, 3 positions and the long chain fatty acid at the sn-2 position. According to this method, highly pure symmetric triglycerides comprising a medium-chain fatty acid at sn-1 and 3 positions and a long chain fatty acid at sn-2 position can be industrially efficiently produced.
