Description
Technical Field
The invention belongs to the technical field of deep processing of soybean byproducts, and particularly relates to a method for extracting soybean fiber and bean dreg protein by combining a homogeneous auxiliary alkaline method.
Background
China is a large country for producing and processing soybeans, 15-20% of bean dregs are produced in the production and processing process of the soybeans, and currently, about 280 ten thousand tons of bean dregs are produced in China every year. The bean dregs contain more than 70% of cellulose and about 15% of protein, and soybean fiber and bean dregs protein can be further extracted. The soybean fiber has strong physiological activity, the bean dreg protein amino acid composition is reasonable, and the soybean fiber is similar to the soybean protein isolate composition; however, most of soybean fibers are water-insoluble fibers, and the okara protein is tightly combined with other components in the okara, so that the extraction difficulty is very high, the development and application degree of okara resources in China is very low, and the okara is mostly used as animal feed or waste treatment. Therefore, how to reasonably and efficiently develop and apply the soybean fiber and the bean dreg protein plays a key role in improving the fine and further processing of the bean dreg by-product.
Although our country has rich bean dregs resource, the bean dregs have huge development potential, but the development and application of the bean dregs in our country have breakthrough progress at present. The existing development research on the bean dregs mainly focuses on: (1) treating bean dregs by high static pressure, high pressure homogenization, ultrasound and other modes to extract soluble dietary fiber; or optimizing the extraction process of the bean dreg protein by adopting chemical solvent, ultrasonic wave and other modes. These studies focus on the extraction of a single substance from the okara, but only partially increase the extraction rate or purity of such a single substance, and do not significantly improve the functional properties of these extracts; (2) the soybean peptide is prepared by taking the bean dregs as a raw material or fermenting and producing the soybean peptide by taking the bean dregs as a base material by combining an enzymolysis technology or a fermentation technology, and the research is based on the rich nutritive value of the bean dregs and emphasizes the development and application of the whole bean dregs, but the yield or the fermentation effect of the soybean peptide is limited, and the large-scale production is difficult to carry out. In summary, the main reasons for restricting the development and research of the bean dregs are: (1) the extraction difficulty is high, and the extract is single. Due to the limitations of poor solubility of cellulose and high protein binding degree of the soybean dregs, most researches focus on improving the extraction process of soybean fiber or soybean dregs protein, and concentrate on extracting a certain substance in the soybean dregs, so that other substances are easy to discard; (2) the functional characteristics are not good enough. The extraction process affects not only the extraction yield and purity of the material, but also the structural and functional properties of the material. The existing research focuses on optimizing the extraction rate or purity of the soybean fiber or the soybean dreg protein in the soybean dregs, and the change of the functional characteristics of the soybean fiber or the soybean dreg protein in the extraction process is rarely concerned, so that the research for improving the functional characteristics of the soybean fiber or the soybean dreg protein by using the extraction processes is less beneficial.
