Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A free polyunsaturated fatty acid-containing composition, comprising at least one free polyunsaturated fatty acid having 20 or more carbons in an amount that a content thereof is 80.0% or greater of fatty acids in the composition, wherein the free polyunsaturated fatty acid-containing composition satisfies at least one selected from the group consisting of conditions (1) and (2): (1) a content of a conjugated unsaturated fatty acid being from 0.001% to 1.0% of the fatty acids in the composition; and (2) the Gardner color being less than 3+. 2. The free polyunsaturated fatty acid-containing composition according to claim 1 , wherein the free polyunsaturated fatty acid-containing composition has an anisidine value of 5.0 or less. 3. The free polyunsaturated fatty acid-containing composition according to claim 1 , wherein a content of the fatty acid alkyl ester is 0.2% or less of the fatty acids in the composition. 4. The free polyunsaturated fatty acid-containing composition according to claim 1 , wherein the content of the conjugated unsaturated fatty acid is from 0.01% to 0.8% of the fatty acids in the composition. 5. The free polyunsaturated fatty acid-containing composition according to claim 1 , wherein the polyunsaturated fatty acid is at least one selected from the group consisting of eicosadienoic acid, dihomo-y-linolenic acid, Mead acid, eicosatetraenoic acid, arachidonic acid, eicosapentaenoic acid, docosatetraenoic acid, docosapentaenoic acid, and docosahexaenoic acid. 6. The free polyunsaturated fatty acid-containing composition according to claim 1 , wherein a total content of a residual organic solvent in the composition is 5000 ppm or less. 7. The free polyunsaturated fatty acid-containing composition according to claim 1 , wherein a content of a di- or higher-valent polyunsaturated fatty acid having 18 carbons in the composition is 2.0% or less of the fatty acids in the composition.
