METHOD FOR INCREASING STABILITY OF COMPOSITION CONTAINING OMEGA-3 POLYUNSATURATED FATTY ACIDS Russian patent published in 2019 - IPC A23D7/00 A23L33/105 C11B5/00 

FIELD: food industry.

SUBSTANCE: invention relates to oil and fat industry. Method for increasing resistance to oxidation of a fat composition containing omega-3 polyunsaturated fatty acids, involving the following stages: (i) providing an initial composition containing at least one component which is an omega-3 polyunsaturated fatty acid; (ii) providing a lysine-based composition; (iii) mixing aqueous, aqueous-alcoholic or alcoholic solutions of each of the original composition and the lysine-based composition to obtain a mixture which is spray-dried to form a composition in form of a solid product containing at least one salt formed by a cation, obtained from lysine by protonation, and an anion derived from omega-3 polyunsaturated fatty acid by deprotonation. Composition in form of a product is characterized by content of SC solvent selected from the following: SC < 5 wt. %, SC < 3 wt. %, SC < 1 wt. %, SC < 0.5 wt. %, as well as the ratio R = n(ca)/n(lys) of the amount of carboxylic acid functional groups n (ca) in the initial composition provided in step (i), to the amount of lysine n(lys) in the lysine-based composition provided in step (ii) in the range selected from 0.9 < R < 1.1, 0.95 < R < 1.05, 0.98 < R < 1.02. Fat composition containing omega-3 polyunsaturated fatty acids obtained by the method described above. Fat composition containing omega-3 polyunsaturated fatty acids, as per cl. 4 is used for production of food products containing omega-3 polyunsaturated fatty acids; for production of nutrient products containing omega-3 polyunsaturated fatty acids; for the manufacture of pharmaceutical products containing omega-3 polyunsaturated fatty acids.

EFFECT: invention enables to obtain an oxidation-resistant fat composition.
