FIELD: food industry.
SUBSTANCE: invention relates to production of health food production. Product protein equivalent proposed for treating of people suffering from phenyl ketonuria production method includes preporation of protein containing biological system - concentrate of whey proteins, hydrolysis, separation of phenylalanine, condensation and drying. For separation of phenylalanine hydrolysate is processed with a ferment providing turning of phenylalanine into tyrosine for instance phenylalanine-4-hydroxylase in quantity of 0.0001-5% of protein weight. After that inactivation of ferment is performed by short-time warming up to 90°C during 3-5 seconds. Protein hydrolysate condensation free from phenylalanine is performed till dry substances content 30-50%. Drying is performed till dry substances content 14%.
EFFECT: invention allows to obtain product with improved treating effectively due to reduce of phenylalanine content in protein equivalent.
