A novel, highly nutritious, protein-rich, solid food product comprises fermented and autolyzed proteinaceous material, usually meat, fish or other animal tissue, bound into coherent pieces by a gelled or coagulated binder and stabilized against microbiological activity by an acid pH value, preferably below 5.5. The starting material is comminuted, an acid-producing fermentation culture, for example of Lactobacillus species, is added with fermentable carbohydrate, and the mixture incubated until the pH value has fallen to 4 or below. A coagulable or gellable binder, such as gluten or xanthan gum, is then incorporated, preferably also with antimycotic, and the product shaped, for example by extrusion, and cooked.

Pet food and method of making same

A novel, protein-rich food product, especially suitable for domestic animals, is made by subjecting protein material such as meats or fish to acid-producing fermentation, and preferably also to autolysis or proteolysis, and adding the acidic fermented material to a colloidal solution of protein, such as milk or soya milk, whereupon the diposed protein is precipitated and forms a curd that entraps and binds the particles of fermented material. The curd and entrapped material are separated off and compacted into a coherent mass. The product, which is a compacted mass of the precipitated protein with particles of the fermented material distributed through it, can have the consistency of a cheese and may be formed into 'cheese' shapes. The flavor of the product is influenced by the nature of the fermented material.
