The invention discloses a method for producing vegetarian ham sausages through twin-screw
extrusion. The vegetarian ham sausages are produced by performing pretreatment on vegetable
protein powder,
isolated soy protein and vital
wheat gluten as raw materials through, and then mixing and stirring the pre-treated raw materials by adopting a twin-screw extruder and a twin-screw
extrusion technology for completing the processes such as
extrusion curing, denaturation and texturization forming for one time. The method completely takes the vegetable
protein powder as the
raw material without adding any additives or auxiliary materials, so that the vegetarian ham sausages are good in texturization structure, high in
protein content, similar to meat taste in taste, smooth in appearance, compact in structure and stable in quality, the
moisture content of final products can be up to 50%, and the vegetarian ham sausages can be eaten as leisure food and
staple food. By utilizing the twin-screw extruder for production, the method is a
continuous mixing, melting and forming process, and as a high-temperature instantaneous biochemical reactor, the twin-screw extruder has the outstanding advantages of high efficiency and energy, low cost,
energy consumption and the like, and also has the characteristics of high volume of the production,
continuous production process, realization of the large-scale industrialized production, stable product quality, high degree of
automation, small occupying area for the production and the like.
