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. In this manner the mixture is subjected to further axial and transverse displacement forces in the second extruder barrel in order to adequately work and stretch the protein therein while being subjected primarily to axially directed displacement forces in the elongated die spacer for facilitating the formation of a layered meat-like structure therein prior to extrusion; in addition, conditions of temperature and pressure are controlled so that the resultant product is relatively dense and unexpanded. In other forms, the density, chewiness and other properties of the analogue products hereof can be selectively altered by the addition of coloring agents, pH modifiers or other ingredients, or by varying the process conditions.
