WIPO Patent Application WO/2017/038860
Kind Code:
A1
Abstract:
The present invention is: a free polyunsaturated fatty acid-containing composition, which comprises at least one C20 or higher free polyunsaturated fatty acid, 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 feedstock composition containing at least one C20 or higher polyunsaturated fatty acid, and hydrolysis of a reaction solution containing the prepared feedstock composition, a lower alcohol, water and an alkali catalyst at a temperature of 10°C or lower.
