Fat of Baikal seal contains a large amount of polyunsaturated fatty acids (PUFAs) and is a promising source for the production of biologically active supplements. The article describes a method for producing PUFAs concentrate from fat of Baikal seal and the study of fatty acid composition of the produced concentrate. The overall level of unsaturated fatty acids in the produced concentrate amounts for 92.67%, including É-3 PUFAs in amount of 12.2% and -6 PUFAs in amount of 15.91% that testifies high biological value of the concentrate. https://www.biotech-asia.org/vol11_nospl_edn2/development-of-a-method-to-produce-a-concentrate-of-polyunsaturated-fatty-acids/ Polyunsaturated fatty acids (PUFAs); arachidonic acid (AA); Eicosapentaenoic acid (EPA); docosahexaenoic acid (DHA); concentrate of PUFAs
