METHOD FOR OBTAINING MILK PROTEIN CONCENTRATE Russian patent published in 2023 - IPC A23J1/20 A23J3/08 A23C9/142 A23J3/34 A23C7/04 

FIELD: biotechnology.

SUBSTANCE: invention relates to the field of biotechnology, in particular, to the dairy industry. The method for obtaining milk protein concentrate from skimmed milk includes a membrane cascade, including a microfiltration stage with ceramic membrane elements with a pore size of 800 nm, a microfiltration stage with ceramic membrane elements with a pore size of 200 nm, a diafiltration stage with ceramic membrane elements with a pore size of 10-20 nm, as well as the hydrolysis of lactose residues using beta-galactosidase and spray drying of the hydrolysis product at a temperature above 130°C to obtain dry milk protein concentrate. The invention also concerns the use of the specified membrane cascade for the production of milk protein concentrate, free from the presence of residues of veterinary drugs, with a low lactose content. EFFECT: invention makes it possible to obtain a product free from the presence of residues of veterinary drugs, with a low lactose content from milk with residual contents of veterinary drugs. 5 cl, 3 dwg, 2 tbl, 7 ex
