METHOD FOR PRODUCTION OF PROTEIN MILK PRODUCT WITH CONCENTRATE OF MICELLAR CASEIN Russian patent published in 2024 - IPC A23C9/12 A23J3/10 

FIELD: dairy industry.

SUBSTANCE: method for production of protein milk product with concentrate of micellar casein, characterized by that preliminarily obtained and pasteurized skimmed milk is subjected to microfiltration using semi-permeable ceramic membranes with pore diameter of 0.1 mcm at temperature of 10–15 °C and pressure of 0.2–0.3 MPa to a weight fraction of dry substances in concentrate of 12–16%; then two successive stages of diafiltration of the obtained concentrate are carried out with a double volume of reverse osmosis water in relation to the volume of the concentrate at each stage of diafiltration at operating modes of the membrane plant, similar to the microfiltration process, until a concentrate is obtained with a volume equal to the volume of the concentrate initially sent for diafiltration; characterized in that the obtained concentrate, which is a concentrate of micellar casein with a ratio of casein: whey proteins of 93:7 with a weight fraction of casein of not less than 10.0 %, a weight fraction of fat of not more than 0.25%, pasteurized at temperature of 85±2 °C with holding for 20 s; cooled to temperature of 32–33 °C; mesophilic starter is added to the mixture and stirred for at least 15 minutes; coagulation is carried out at temperature of 27±5 °C depending on the season for not more than 12 hours; then clot is cut into cubes with size of 2.0×2.0×2.0 cm and left alone for separation of serum for 15–20 minutes, and then the clot is slowly boiled at a whey temperature of 50±2 °C for 2 hours; further serum is removed; protein mass is self-pressed and pressed to moisture weight fraction of not more than 80 %; finished product is packed and marked.

EFFECT: invention enables to obtain a product with high biological value, expand the range of dairy products, intensify the production process, as well as increase the output of the finished product.
