  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.

  一种高度不饱和脂肪酸或高度不饱和脂肪酸乙酯，它是以含有高度不饱和脂肪酸作为组成脂肪酸的脂肪或油作为原料油生产的，其环境污染物含量已经降低，其中所含的二恶英中，多氯二苯并对二恶英（PCDD）和多氯二苯并呋喃（PCDF）的含量低于 0.05 pg-TEQ/g，共面多氯联苯（Co-PCB）的含量低于 0.03 pg-TEQ/g。05 pg-TEQ/g，共面多氯联苯（Co-PCBs）含量低于 0.03 pg-TEQ/g。本发明还公开了一种生产高度不饱和脂肪酸或高度不饱和脂肪酸乙酯的方法，其步骤是通过薄膜蒸馏法从原料油中去除游离脂肪酸和环境污染物，对所得脂肪或油进行乙酯化，并通过精馏和柱层析法对其进行精制。
