The invention relates to a method for improving the quality of high-
moisture peanut drawing
protein by TG
enzyme. The method comprises the following steps: pulverizing low-temperature defatted peanut
protein powder, and uniformly mixing the peanut
protein powder with a right amount of TG
enzyme; conducting extruding and texturizing treatment, wherein the
extrusion temperatures are sequentially as follows: a feed zone is 60-80 DEG C, a
mixing zone is 80-100 DEG C, a cooking zone is 130-160 DEG C, a cooling zone is 90-130 DEG C, and a molding zone is 50-90 DEG C; adding water on line in the
extrusion process, and regulating the
moisture of the material to be 45%-65%; and cooling after
extrusion molding for preparing the high-
moisture peanut drawing protein. The high-moisture peanut drawing protein produced by the method provided by the invention is
bright white in color, subtly fragrant in taste, smooth in surface, rich in
fiber silk-like structures, rich in
fiber-like structures and high in the intensity of
fiber silks, and can be used as a substitute for high-grade meat for
processing vegetarian beef. The method increases the fibration degree of the high-moisture peanut drawing protein, enhances the intensity of the fiber silks and extends the application range of the high-moisture peanut drawing protein.
