  • Patent number: 3970761
    Abstract: A dense, uniformly layered, relatively unexpanded extrusion cooked vegetable protein based meat analogue product, which has meat-like texture, mouth-feel and appearance characteristics permitting use of the product as a full substitute for meats such as pork, beef, fish and poultry is made up of a mixture of a vegetable protein such as defatted soy flour and moisture which is extrusion processed to present an analogue having a plurality of juxtaposed, manually separable meat-like layers which are substantially untwisted relative to each other and strongly resemble real meat. The product is prepared by extruding a vegetable protein-water mixture in a first extrusion cooker under conditions to render the mixture hot and flowable but still substantially unoriented, whereupon the mixture is passed through a second extrusion cooker which is equipped with a hollow tubular spacer on the extrusion end thereof.
