PROCESS FOR PREPARATION OF TRIGLYCERIDE AND TRIGLYCERIDE COMPOSITION

摘要

Triglyceride wherein all three fatty acids are C20+ polyunsaturated fatty acids (with at least three double bonds) is prepared by esterification of glycerol with free polyunsaturated fatty acid or its C1-4 lower alkyl ester in the presence of a lipase. The yield of triglyceride is increased and the amount of mono- and diglyceride decreased by removing water or lower alcohol formed during the reaction, by using positionally non-specific lipase, and/or by using a lipase immobilized by adsorption on a particulate, macroporous adsorbent resin of the acrylic type.
