METHOD OF PRODUCING FOOD PHOSPHOLIPID PRODUCT Russian patent published in 2024 - IPC A23D9/02 

FIELD: food industry; oil and fat industry.

SUBSTANCE: method of producing a food phospholipid product, comprising mixing raw vegetable phospholipids with acetone, separating the mixture into a solution of neutral lipids in acetone and phospholipids under vacuum, mixing phospholipids with acetone, treating the mixture by ultrasound exposure and separating the mixture into a solution of neutral lipids in acetone and phospholipids under vacuum, mixing phospholipids with acetone, treatment of the mixture by ultrasound exposure and separation of the mixture into a solution of neutral lipids in acetone and phospholipids under vacuum, drying the phospholipids under vacuum and mixing them with ethanol, treating the mixture by ultrasound exposure, separation of the liquid phase and removal of ethanol from the liquid phase under vacuum to obtain phospholipids, mixing them with 90% ethanol at temperature of 40-50 °C, the ratio of phospholipids : 90% ethanol, is equal to from 1:10 to 1:12, and intensive mixing for 5-7 minutes to obtain a phospholipid solution, mixing the obtained phospholipid solution with 2.0-3.0% calcium chloride solution in 90% ethanol at temperature of 40-50 °C, ratio of phospholipids : calcium chloride solution is equal to from 1:4 to 1:5, and constant stirring for 2-3 minutes, treatment of obtained mixture by ultrasound exposure with specific power of 0.28-0.32 W/cm³ for 5-7 minutes with discreteness of 10 seconds after each minute of treatment, separation of liquid phase from mixture by vacuum filtration and removal of ethanol from liquid phase under vacuum to obtain target product.

EFFECT: invention enables to obtain a food phospholipid product with a high content of phosphatidylcholines of more than 80%.
