FIELD: chemistry, organic.
SUBSTANCE: invention relates to butter-fat industry. Stable oil, containing LC-PUFA in form of triacylglycerins, namely, arachidonic acid (ARA), dihomo-gamma-lynolenic acid (DHGLA), docosahexaenoic acid (DHA) or eicosapentaenoic acid (EPA), is obtained by direct pressing of one or more biomasses obtained from microorganism cultures, especially fungi or microalgae, which contain acids ARA, DHGLA, DHA or EPA, until oil of first pressing and residue of first pressing are obtained. Obtained oil is part of food product, babyfood product - both as separate component and in combination with fish oil, of food composition, cosmetic composition, as well as of animal food product. Animal food product contains biomass residue, obtained after removal of oil from biomass.
EFFECT: obtaining stable oil, which contains one or more polyunsaturated fatty acids from biomass in form of triacylglycerins, in purified state and with high yield, with minimal degree of oil decomposition.
