Free polyunsaturated fatty acid-containing composition and manufacturing method therefor

Abstract

The present disclosure is: a free polyunsaturated fatty acid-containing composition, which comprises at least one free polyunsaturated fatty acid having 20 or more carbon atoms, the content being at least 80.0% of the fatty acids in the composition, and satisfies at least one selected from a group consisting of conditions (1) and (2): (1) the content of conjugated unsaturated fatty acid is 1.0% or less of the fatty acids in the composition, and (2) the Gardner color is less than 3+; and a manufacturing method for the free polyunsaturated fatty acid-containing composition comprising the preparation of a raw material composition containing at least one polyunsaturated fatty acid having 20 or more carbon atoms, and hydrolysis of a reaction solution containing the prepared raw material composition, a lower alcohol, water and an alkali catalyst at a temperature of 10° C. or lower.
