METHOD FOR PRODUCING A FOOD PHOSPHOLIPID PRODUCT Russian patent published in 2023 - IPC A23D9/02 

FIELD: animal or vegetable oils.

SUBSTANCE: invention relates to the fat and oil industry and can be used to produce a food phospholipid product used in the production of foodstuffs, including functional and specialised foods. Proposed is a method for producing a food phospholipid product, including the stage of mixing raw plant-based phospholipids with an organic solvent, separating the phases into a solution of neutral lipids in an organic solvent and phospholipids, further drying the phospholipids under vacuum; wherein the mixing is performed in three stages: at the first stage, the raw plant-based phospholipids and the organic solvent are mixed at a raw vegetable phospholipids : organic solvent ratio (by weight) (1:6) to (1:7) and at a temperature of 35 to 40 °C by intensely stirring for 5 to 7 minutes, and after the second and third stages of mixing the phospholipids with the organic solvent, the resulting mixture is treated by exposure to ultrasonic effect with an intensity of 140 to 180 W/cm² for 1 minute with a discreteness of 10 seconds, with 3 to 5 minutes total time of ultrasonic effect at each stage; wherein the mixing at the second and third stages is performed by intensely stirring for 5 to 7 minutes, and the phases are separated into a solution of neutral lipids in an organic solvent and phospholipids, after the first stage of mixing and after treating the mixture produced at the second and third stages of mixing by ultrasonic effect, under vacuum.

EFFECT: duration of the production process shortened by 9.5 hours, output of the target product increased by 1.6 to 1.7%, and improved quality thereof.
