Abstract

Official abstract text for this publication.

PROBLEM To provide a composition comprising highly enriched PUFA or its alkyl esters while containing fatty acid esters of 3-MCPD at adequately low concentrations and to provide an efficient method for producing the composition.MEANS FOR SOLVING A composition that contains fatty acids or fatty acid alkyl esters as its major component, the composition containing highly unsaturated fatty acid or alkyl ester thereof, wherein the proportion of the highly unsaturated fatty acid in the constituent fatty acids of the composition is 50 area % or more and wherein the concentration of 3-MCPD as found upon analyzing the composition by American Oil Chemists' Society official method Cd 29b-13 assay A is less than 1.80 ppm.

First claim

Opening claim text (preview).

What is claimed is: 1. A composition that contains fatty acids or fatty acid alkyl esters as its major component, the composition containing highly unsaturated fatty acid or alkyl ester thereof, wherein the proportion of the highly unsaturated fatty acid in the constituent fatty acids of the composition is 50 area % or more and wherein the concentration of 3-MCPD as found upon analyzing the composition by American Oil Chemists' Society official method Cd 29b-13 assay A is 0.01 ppm or more and less than 1.80 ppm. 2. The composition according to claim 1 , wherein the proportion of the highly unsaturated fatty acid in the constituent fatty acids of the composition is 70 area % or more. 3. The composition according to claim 1 , wherein the highly unsaturated fatty acid is eicosapentaenoic acid, docosahexaenoic acid, dihomo-γ-linolenic acid, arachidonic acid, or a combination thereof. 4. The composition according to claim 1 , which is a distillation product. 5. The composition according to claim 1 , wherein the composition is derived from a raw material selected from a fish oil, a microorganism oil, a vegetable oil or a marine animal oil.
