  • Patent number: 5437885
    Abstract: A method for processing a dehulled, defatted oilseed protein meal, e.g., soybean meal, to produce non-porous, meat-like fibers comprises preparing an oilseed protein source and water mixture, extruding the mixture under predetermined conditions, coating the extruded mixture with an edible oil or fat and then further extruding the oil- or fat-coated fibers under specified conditions. The mixture may further comprise meats, fruits, and/or other vegetables as a source of water. The extrusion conditions and the oil or fat coating act to inhibit the expansion of the extruded, non-spongy fibers. The resulting product has a non-porous texture and resembles broiled meat fibers.

  • Patent number: 5300312
    Abstract: A method of producing a ready-to-eat intermediate-moisture texturized protein foodstuff which simulates meat and has an extended shelf life comprises pretexturizing a vegetable protein source with a first source of water such as meat, meat by-products or other liquids by cooking/extrusion, combining the texturized fraction with other ingredients in a second cooking/extrusion step, and pasteurizing the final mixture. Shelf stability is achieved through control of free water content and activity in the product.
