METHOD FOR PRODUCING ACIDIFIED PROTEIN PRODUCT FROM CASEIN AND PRODUCT THUS OBTAINED Russian patent published in 2021 - IPC A23C20/00 A23J1/20 A23J3/10 

FIELD: dairy industry.

SUBSTANCE: method for producing an acidified protein product involves the following steps. Method provides raw material containing casein and treated with a cross-linking enzyme. Method comprises the step of acidifying the material using mesophilic or thermophilic starches and optionally adding the calcium solution to the raw material to form a gel, having pH value in range of 4.4–5.0. Formed gel is cut into a mass formed from grains and/or cubes. Method comprises performing a mass pasteurisation step, at which the mass temperature is increased to a temperature in the range of about 45 °C to about 90 °C while stirring to produce a pasteurized mass. Water part is separated from pasteurized mass to produce acidified protein product in form of grains. Optionally, the grains are pressed into the block. Optionally one imparts flavor and/or packs grains or a block. Acidified protein product contains casein, the protein content ranges from about 10 % to about 50 % (wt/wt) and pH from about 4.4 to about 4.9. Product is in form of grains and is resistant to frying.

EFFECT: group of inventions ensures production of a stable product during thermal treatment or with the help of microwaves.
