METHOD FOR PRODUCTION OF PROTEIN CONCENTRATE OF WHEY Russian patent published in 2012 - IPC A23J1/20 A23C21/00 

FIELD: food industry.

SUBSTANCE: invention relates to dairy industry and may be used for production of a whey protein concentrate for enrichment and manufacture of various food products. The method envisages milk whey collection, separation, pasteurisation in standard modes, cooling to a 15-25°C temperature, introduction of a 3-7% water-soluble chitosan solution produced based on prepared water, (the dose equal to 4-12%), thorough stirring, maintenance during 20-30 minutes, the protein concentrate separation by the centrifugal method. One uses whey with active acidity equal to 4.0-4.8 units or controls whey acidity within the range of 4.0-4.8 units by way of introduction of acid milk whey (with acidity equal to 200°T), lactic acid or by way of ripening with pure cultures of lactic acid microorganisms.

EFFECT: invention allows to accelerate and simplify the chitosan solution preparation process to intensify the whole process, increase the degree of protein substances extraction from milk whey up to 90-96%.
