MIXTURES OF POLAR LIPIDS, PRODUCTION AND USE THEREOF Russian patent published in 2013 - IPC C07F9/10 A23J7/00 A23L1/29 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing a lipid preparation which contains phosphatidylcholine (PC), phosphatidylethanolamine (PE), phosphatidylserine (PS) and phosphatidylinositol (PI), and sphyngomyelin (SM), a composition containing a mixture of said lipids and use thereof. The method involves steps of removing non-lipid material from bovine milk by dispersing the lipids in a mixture of a polar organic solvent and a nonpolar solvent, followed by separation of the lipid fraction and removing the solvent from said fraction, a step of de-oiling the obtained lipid fraction in order to remove nonpolar lipids by dissolving in acetone or supercritical CO₂ and a step of filtering and drying the obtained lipids. In the lipid composition obtained using said method, the ratio of phospholipids is comparable with that of phospholipids in human breast milk. Disclosed is use of the composition obtained using the disclosed method as a source of human breast milk fat for making infant formula.

EFFECT: method enables to obtain a human breast milk substitute by processing readily available material and use thereof to make infant formula.
