Abstract
Disclosed is a method for producing fibrous protein materials useful for fish analogs. According to this method, an aqueous mixture of a heat coagulable protein is frozen by cooling the mixture in a manner and at a rate effective to produce elongated ice crystals generally aligned perpendicular to the surface of cooling, then subjected to a temperature substantially different from that of the frozen mass, and the protein in the frozen mass is then stabilized effectively to preserve its structural integrity during subsequent heating to set the protein.
Claims10
A method for preparing a texturized protein material comprising:
- (a) preparing a mixture comprising heat coagulable protein and water;
- (b) cooling the mixture to freeze the water into elongated ice crystals and to separate the protein into well-defined, well-ordered, substantially independent zones;
- (c) subjecting the frozen mass to a temperature at least 50.degree. C different from that of the frozen mass to cause shock fracturing of the material at lines of weakness in the frozen mass perpendicular to the elongated ice crystals;
- (d) stabilizing the protein in the frozen mass effectively to prevent loss of fibrous structure upon subsequent heating;
- and
- (e) heating the stabilized material to coagulate the protein.
