Method for producing instant mock meat by using isolated soy protein

The invention discloses a method for producing instant mock meat by using isolated soy protein, which belongs to the field of food processing. The method comprises the following steps of: using the isolated soy protein as the main raw material; adding water-soluble soybean polysaccharide and insoluble soybean polysaccharide into the isolated soy protein in certain proportion; and performing the processes of raw material mixing, thermal refining, extrusion texturization, cutting, cooling, packaging and the like to obtain the instant mock meat. The method has the following advantages that: (1) the instant mock meat is not added with any exogenous source component; (2) the proportion of the isolated soy protein in the product can reach 50 to 83 percent; (3) the color and the luster of the product can be diversified; (4) the texture and the quality of the product can be obtained by changing the proportions of the soluble soybean polysaccharide and the insoluble soybean polysaccharide in the materials; and (5) the
