Method for producing soybean tissue protein by using high-temperature soy bean dregs as raw material

Abstract

The invention discloses a method for producing soybean tissue protein by using the high-temperature soy bean dregs as the raw material, belonging to the filed of the food processing biotechnology. According to the technical scheme, the method comprises the following steps: dissolving compound protease in water to prepare protease solution, wherein the addition amount of the compound protease is 0.1-0.5 percent of that of the high-temperature soy bean dregs; stirring evenly the high-temperature soy bean dregs and the protease solution in a stirrer, wherein the proportion of the high-temperature soy bean dregs to the protease solution is 1:0.5; and activating the protein in the high-temperature soy bean dregs by decomposing with the protease solution at 30-50 DEG C for 12-20h; extruding the activated high-temperature soy bean dregs into the soybean tissue protein in a soybean tissue protein forming machine; and drying and packaging the soybean tissue protein to obtain the soybean tissue protein product. The high-temperature soy bean dregs are activated by being decomposed with the protease, thus the nitrogen solubility index is increased, and the organization effect and the fibrosis effect of the protein can be improved. The soybean tissue protein product is in the structure of fiber, is chewable and has no bitter flavor and beany flavor. The method has the characteristic of mild reaction condition, is beneficial to improving the ecology and environment and producing the natural products and meets the demands of green chemistry.

Description

Technical field: [0001] The invention relates to a production method of soybean tissue protein, which utilizes microbial enzymolysis technology to activate high-temperature soybean meal protein to produce soybean tissue protein, and belongs to the field of food biotechnology processing. Background technique: [0002] my country is the birthplace of soybeans, and soybean production has always been among the top in the world. Plant protein organization is a new food processing method developed in the 1970s. At present, in the case of severe shortage of animal protein supply, plant protein organization is an important direction to improve the human diet and provide high-protein nutritious food. At present, the production of tissue protein at home and abroad uses low-temperature soybean meal and protein isolate as raw materials. However, more than 95% of soybean meal produced by my country's existing soybean oil processing enterprises is high-temperature soybean meal. Because the ...

Problems solved by technology

Since the protein in high-temperature denatured soybean meal is almost completely denatured, highly denatured defatted soybean meal cannot be processed into tissue protein and can only be used as feed
