PURPOSE:To prepare a texturized protein food, by using a specific highly denaturated vegetable protein as a raw material and treating with a twin-screw extruder at a specific temperature, thereby texturizing the vegetable protein which is unable to be texturized by conventional method. CONSTITUTION:A texturized protein food which can be used as a substitute for a part or total of meats in a food prepared from meats, by treating a vegetable protein having a soluble nitrogen index of <=15 [preferably (processed) soybean having a fat content of <=5%] with a twin-screw extruder while keeping the protein at 180-250 deg.C at least once or more, thereby texturizing the protein. A texturized protein food suitable for the alimentary therapy for renal diseases, etc., can be prepared by using a treated soybean having decreased phosphorus and calcium contents as a raw material. |
