Abstract
The present invention provides a method of producing a composition containing docosahexaenoic acid as a constituent fatty acid of glycerides. The method includes hydrolyzing a feedstock oil containing glycerides, the glycerides including docosahexaenoic acid as a constituent fatty acid, by action of a first lipase and a second lipase, to increase the proportion of docosahexaenoic acid in glyceride fractions. The first lipase is at least one lipase selected from the group consisting of a lipase obtained from a microorganism of the genus, a lipase obtained from a microorganism of the genus, a lipase obtained from a microorganism of the genus, and a lipase obtained from a microorganism of the genus. The second lipase is a partial glyceride lipase.
