고도 불포화 지방산을 구성 지방산으로서 함유하는 유지를 원료유로 하여 제조되고, 환경 오염 물질의 함유량이 저감된, 고도 불포화 지방산 또는 고도 불포화 지방산의 에틸에스테르로서, 함유되는 다이옥신류 중, 폴리염화디벤조파라다이옥신 (PCDD) 및 폴리염화디벤조푸란 (PCDF) 의 함유량이 0.05 pg-TEQ/g 미만, 코플레이너 PCB (Co-PCB) 가 0.03 pg-TEQ/g 미만인 고도 불포화 지방산 또는 고도 불포화 지방산의 에틸에스테르 및 그 제조 방법으로서, 원료유로부터, 박막 증류에 의해 유리 지방산 및 환경 오염 물질을 제거하고, 얻어진 유지를 에틸에스테르화하고, 정류 및 칼럼 크로마토그래피에 의해 정제를 실시하는 방법. A highly unsaturated fatty acid or a highly unsaturated fatty acid ethyl ester that has been produced using as a feedstock oil a fat or oil that contains highly unsaturated fatty acids as constituent fatty acids and which has been reduced in the contents of environmental pollutants, wherein among the dioxins contained, polychlorinated dibenzoparadioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are contained in amounts of less than 0.05 pg-TEQ/g and coplanar PCBs (Co-PCBs) in amounts of less than 0.03 pg-TEQ/g. Also disclosed is a method for producing the highly unsaturated fatty acid or highly unsaturated fatty acid ethyl ester by the steps of removing free fatty acids and environmental pollutants by thin-film distillation from a feedstock oil, ethyl esterifying the resulting fat or oil, and refining the same by rectification and column chromatography.
