ABSTRACT:
A method of processing whole soybeans to produce discrete, irregularly-shaped chunks or pieces of textured proteinaceous material which are free from off-flavors and odors and have a meat-like texture and appearance. Whole soybeans are hydrated and acidified to a pH in the range of about 4.5 to 6.5 and the pH of the soybeans is maintained in this range throughout processing. The acidified whole soybeans are ground in an aqueous medium to provide an aqueous slurry or dough of soybean particles having a pH in the range of 4.5-6.5. The aqueous acidic slurry or dough is passed through a confined treatment zone in which high temperature pressurized steam is injected directly into a confined stream of the slurry or dough under conditions which effect texturization of the soy protein in the form of discrete chunks or pieces which are discharged from the treatment zone. The texturized pieces, when discharged from the treatment zone or when dried and rehydrated are free of off-flavors and odors and have a meat-like texture, firmness and appearance. They are suitable for use in a wide variety of food products, including frozen products, canned products and dry mix products. If desired, additives such as flavoring, coloring, fat, seasoning and other proteinaceous materials, including soy protein isolate, may be incorporated in the texturized soy protein pieces to modify the texture of the texturized pieces.
