METHOD FOR INCREASING STABILITY OF COMPOSITION CONTAINING OMEGA-6 POLYUNSATURATED FATTY ACIDS Russian patent published in 2019 - IPC A23D7/00 A23L33/115 C11B5/00 

FIELD: food industry.

SUBSTANCE: invention relates to the food industry. Method for increasing resistance to oxidation of a fat composition containing omega-6 polyunsaturated fatty acids envisaging the following stages: (i) providing an initial composition containing at least one component which is an omega-6 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, thus, 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-6 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) is in the range selected from 0.9 <R <1.1, 0.95 <R <1.05, 0.98 < R <1.02. Fat composition produced by the method described above.

EFFECT: use of a fat composition for making food products, nutritional products and pharmaceutical products.
