Изобретение относится к масложировой промышленности и касается переработки рыбьего жира с получением концентратов этиловых эфиров полиненасыщенных высших эфирных кислот. Сущность: в способе переработки рыбьего жира с получением концентрата этиловых эфиров полиненасыщенных кислот, включающем переэтерификацию обезвоженного жира этиловым спиртом в присутствии серной кислоты при атмосферном давлении и 78-80oС, переэтерификат подвергают нейтрализации раствором щелочи, отделяют нейтральные эфиры и подвергают их фракционной перегонке в вакууме с получением высококипящей фракции с содержанием эйкрзапентаеновой и докозагексаеновой кислот не менее 45% в качестве целевого продукта, а также двух низкокипящих фракций в качестве новых дополнительных целевых продуктов с содержанием жирных кислот не менее 1% в одной и не менее 20% в другой.The invention relates to the oil industry and relates to the processing of fish oil with obtaining concentrates of ethyl esters of polyunsaturated higher essential acids. Essence: in the method of processing fish oil to obtain a concentrate of ethyl esters of polyunsaturated acids, which includes the transesterification of dehydrated fat with ethyl alcohol in the presence of sulfuric acid at atmospheric pressure and 78-80 o vacuum to produce a high boiling fraction containing at least 45% eicrzapentaenoic and docosahexaenoic acids as the desired product, as well as two low-boiling fr shares as additional new target products with a fatty acid content of at least 1% in one and at least 20% in another.
