WHEY PROTEIN DENATURATION METHOD Russian patent published in 2012 - IPC A23J3/08 B01F7/00 

FIELD: food industry.

SUBSTANCE: group of inventions relates to a method for denatured whey protein production and to a method for whey protein thermal stability improvement without usage of an additive such as an organic solvent. One prepares a whey protein solution of whey protein with pH from 5.5 to 7.0. The whey protein solution continuously contacts and is blended with the whey protein solution flowing in the form of a thin turbulent current between two concentric cylinders. The blended whey protein solution flowing in the form of a thin turbulent current between the two concentric cylinders is subjected to the effect of shear force, shear velocity equal to 5000 sec^-1 - 25000 sec^-1, at temperature of 76-120°C during a period of time from 0.1 sec to 8 min. After thermal treatment at a temperature of 85°C during 10 min in the course of a heating test denatured whey protein has average particle size from 0.3 to 13.8 mcm.

EFFECT: produced protein has improved thermal stability.
