FIELD: medicine.
SUBSTANCE: what is presented is a method for reduction of re-esterification activity of lipase prepared of Thermomyces sp. and immobilised on a carrier, or a lypase powder mixture which contains a filter excipient and lypase prepared of Thermomyces sp. immobilised on the carrier. The lipase powder mixture is ground to average particle size 1 mcm to 300 mcm. The method is implemented by washing said lypase or lypase powder mixture in triacylglycerol. What is also presented is a method for re-esterification. It involves conducting a re-esterification reaction with the use of said lypase or lypase powder mixture. Then lypase or lypase powder mixture is separated from the reaction system and washed in triacylglycerol for reduction of re-esterification activity. One more re-esterification reaction is conducted with the use of reduced lypase or lypase powder mixture.
EFFECT: method provides effective reduction of low re-esterification activity of lypase or lypase powder mixture to be re-used in the re-esterification reaction.
