发明名称 METHOD FOR PRODUCING HYDROLYSED KERATINACEOUS MATERIAL
摘要 The invention relates to a method for producing digestible keratinaceous material comprising the steps of hydrolysing keratinaceous material in the presence of water in a hydrolyser at elevated temperature and at a pressure between about 2 bar and about 15 bar, and drying the resultant hydrolysed keratinaceous material comprising at least partly insoluble material in a dryer at a temperature/time/pressure combination which limits the drop in pepsin and/or ileal digestibility by less than 10%, and/or such that the pepsin and/or ileal digestibility remains higher than 85%, or such that the pepsin and ileal digestibility remains higher than respectively 75% and 85%. Preferably, the drying of the resultant hydrolysed partly soluble keratinaceous material is performed in a dryer at a temperature such that the keratinaceous material remains at a temperature below 90 º C, preferably below 80 º C.
