METHOD FOR OBTAINING A CONCENTRATE OF PHYTOSTEROLS AND TOCOPHEROLS AS WELL AS FREE FATTY ACIDS Russian patent published in 2023 - IPC C11B3/00 

FIELD: oil and fat industry.

SUBSTANCE: method for obtaining a concentrate of phytosterols and tocopherols, as well as free fatty acids, which consists in mixing vegetable oil deodorization strips with silica gel and sequential solid-phase extraction with petroleum ether and ethyl alcohol, followed by removal of solvents from the resulting miscellas. The deodorization strips of vegetable oils are mixed with silica gel in the mass ratio of the initial components 1:1-1:4 to obtain a suspension, then successive solid-phase extraction is carried out with constant stirring using petroleum ether and ethyl alcohol in such a way that for the first extraction the mass ratio of the suspension to the volume of the solvent is 1:10-1:11, and for the second and subsequent extractions it is 1:5-1:6, while the extraction of each of the solvents is carried out until the components are completely extracted with the corresponding solvent to obtain miscellas, after the extraction is completed, the solvents are removed from the miscellas by vacuum distillation at the boiling point of the solvent.

EFFECT: invention makes it possible to increase the productivity of the method for obtaining concentrates of phytosterols and tocopherols, as well as free fatty acids from vegetable oil deodorization cuts, as well as to reduce the consumption of reagents.
