ABSTRACT A dense, uniformly layered, relatively unexpanded extrusion cooked vegetable protein based meat analogue product is provided, which has meat-like texture, mouth-feel and appear- ance characteristics permitting use of the product as a full substitute for meats such as pork, beef, fish and poultry. In addition, a method and apparatus for making the products hereof is also provided. The product is preferably made up of a mix- ture 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 processing method prefer- ably includes 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 is order to adequately work and stretch the protein therein while being subjected primarily to axially directed displacement forces in the elongated die spacer for facilitat- ing 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 rel- atively dense and unexpanded. In other froms, 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.
