HIGHLY UNSATURATED FATTY ACID OR HIGHLY UNSATURATED FATTY ACID ETHYL ESTER WITH REDUCED ENVIRONMENTAL POLLUTANTS, AND METHOD FOR PRODUCING SAME

摘要

Polyunsaturated fatty acid or polyunsaturated fatty acid ethyl ester of polyunsaturated fatty acid or polyunsaturated fatty acid, which is manufactured using fats and oils containing a polyunsaturated fatty acid as a constituent fatty acid as a raw material oil, and has a reduced content of environmental pollutants. Ethyl esters of polyunsaturated fatty acids or polyunsaturated fatty acids whose content of (PCDD) and polydibenzofuran chloride (PCDF) is less than 0.05 pg-TEQ/g and coplanar PCB (Co-PCB) is less than 0.03 pg-TEQ/g And as a manufacturing method thereof, free fatty acids and environmental pollutants are removed from raw material oil by thin film distillation, the obtained fats and oils are ethylesterified, and purification is performed by rectification and column chromatography.
