PROCESS FOR PRODUCTION OF OIL OR FAT CONTAINING HIGHLY UNSATURATED FATTY ACID USING LIPASE

摘要

[PROBLEMS] To provide a fat containing polyunsaturated fatty acid having a lower saturated fatty acid content. [MEANS FOR SOLVING PROBLEMS] A method for concentrating polyunsaturated fatty acids by reacting glycerides containing polyunsaturated fatty acids with polyunsaturated fatty acids having low reactivity, characterized in that the lipase reaction is carried out at a temperature of 25 ° C or lower . The lipase is preferably a lipase derived from a microorganism belonging to the genus Candida, Alcaligenes genus, Burkholderia genus, Pseudomonas genus, Thermomyces genus, and Lyomucor genus. A glyceride obtainable by this method is a glyceride having a content of docosahexaenoic acid in glyceride of 40% by area or more and a content of saturated fatty acid of 12% by area or less.
