  • Patent number: 4818558
    Abstract: A process for making a fibrous tofu food product having a unique structure, texture, and mouthfeel. Proteinaceous fibers, such as chopped and fluffed wet spun soy isolate fibers, are dispersed in soymilk to form a mixture. A selected edible acid (or acids), calcium and/or magnesium salts, are added to the mixture. The co-precipitate mixture exhibits physical and chemical binding which produces the unique structure or texture. The resulting coagulative mixture can then be formed into desired sizes and shapes.
