ABSTRACT:
A substantially completely water-soluble and pepsin-digestible protein is obtained by the hydrolysis of the keratin contained in animal structures with saturated steam at a pressure of from about 50 to about 250 p.s.i.g. or higher and from about 5 to about 30 parts of liquid water per part of the keratin source, by weight, at the temperature of saturated steam at the pressure employed. Conversion of the keratin to soluble protein and meal is about 80%; the yield of water-soluble protein being as high as about 70%. The water-soluble protein is an excellent animal food.
