METHOD OF PRODUCING EDIBLE LYSOLECITHIN Russian patent published in 2024 - IPC A23D7/01 A23J7/00 

FIELD: oil and fat industry.

SUBSTANCE: method of producing food lysolecithin, involving mixing lecithin with phospholipid content of not less than 95% with distilled water with temperature of 40–45 °C while stirring for 1–2 minutes and a weight ratio of lecithin and distilled water of 1:3 to 1:4, obtained mixture is treated with ultrasonic action with specific power of 0.28–0.32 W/cm³ for 3–5 minutes, phospholipase Al is added at rate of 230–280 activity units per 1 g of phospholipids contained in lecithin, enzymatic reaction is carried out at temperature of 40–45 °C and constant stirring for 40–50 minutes to obtain a fermented mass, and before mixing the fermented mass with acetone, it is treated with a pulsed electric field with intensity of 6–7 kV/cm and the number of single pulses of 72,000 for 8–10 minutes, dried under vacuum at temperature of 50–55 °C, dried fermented mass is mixed with acetone with constant intensive stirring for 20–25 minutes, temperature 50–55 °C, ratio of weight/volume of dried fermented mass and acetone, equal to 1:6 to 1:7, lysolecithin is separated by vacuum filtration and dried under vacuum.

EFFECT: invention increases quality, output and emulsifying capacity of lysolecithin when producing direct oil-in-water emulsions.
