| Abstract: | The object of this work was to establish the optimal technological conditions for the production of protein concentrate from the heads of broiler chickens by enzymic hydrolysis with papain. It was discovered that hydrolysis is most effective at a temperature of 60°C and a pH of about 7, with 2g of enzyme added per kilogramme of raw material. Under these conditions, 100 kg of heads yielded 7 kg of concentrate and 19.2 kg of waste for feed meal. The concentrate obtained contained about 85% protein and demonstrated good organoleptic and physicochemical properties. |
