摘要： The present invention provides a method of producing a composition containing docosahexaenoic acid as a constituent fatty acid of glycerides, comprising hydrolyzing a feedstock oil containing glycerides comprising docosahexaenoic acid as a constituent fatty acid by action of a first lipase and a second lipase, thereby increasing the proportion of docosahexaenoic acid in glyceride fractions, wherein the first lipase is at least one lipase selected from the group consisting of a lipase derived from a microorganism of the genus Thermomyces, a lipase derived from a microorganism of the genus Pseudomonas, a lipase derived from a microorganism of the genus Burkholderia, and a lipase derived from a microorganism of the genus Alcaligenes, and wherein the second lipase is a partial glyceride lipase.
