FIELD: food industry.SUBSTANCE: invention relates to the food industry. Peas are milled； the formed substance is mixed with water to form a suspension and is exposed to pulse ultrasonic vibrations with frequency of 15–20 kHz during 1–3 hours simultaneously with its mixing. Obtained suspension is decanted. Coagulation and separation is performed.EFFECT: invention ensures preservation of the functional potential of the produced protein, increased output of the ready protein, as well as suppression of microflora due to cavitation in the suspension.1 cl, 4 dwg
