Process method for simultaneously extracting soybean function factor and therapeutic factor from bean pulp

Abstract

The invention discloses a process method for simultaneously extracting a soybean function factor and a therapeutic factor from bean pulp, comprising the following scheme: breaking wall of a protein cell by adopting a method for combining ultrasound wave and high-pressure shearing technology, decomposing protein in the bean pulp by selecting an enzymolysis technology of complex enzyme and extracting a functional factor which is micromolecule peptide in the bean pulp by adopting a film separation technology. Four products of micromolecule soybean peptide, soy dietary fiber, soybean oligosaccharide and isolated soy protein can be continuously extracted by taking high-temperature or low-temperature bean pulp as raw materials on one production line and the utility value of the bean pulp of soybean is improved by over 30 times, wherein the total nitrogen content and the content of free amino acid of the micromolecule peptide are respectively not less than 15.0 percent and not less than 2.0 percent and the average molecular weight is mot more than 6,000Dalton. The total sugar content of the soybean oligosaccharide is not less than 90.0 percent; the extraction rate of protein in various effective components of the raw materials is not less than 85 percent and the total sugar content is not less than 82 percent; and the yield of soluble dietary fiber is 11.84 percent.

Description

Technical field: [0001] The invention belongs to a deep processing method of soybean by-products, in particular to a process for simultaneously extracting soybean function and curative effect factors from soybean meal. Background technique: [0002] Soybean meal is a by-product of soybean processing. At present, most manufacturers suffer from the problems of technology and development cost, and can only be used to produce soy sauce or formulated feed, wasting a lot of resources. The small molecule soybean peptide is a low molecular weight peptide with a molecular weight of less than 6000, which is obtained by protease hydrolysis and separation and refinement from soybean protein. It has the effects of easy digestion and absorption, low antigenicity, lowering cholesterol and lowering blood pressure. Soy oligosaccharides are the general term for soluble carbohydrates contained in soybeans, which can inhibit the growth and reproduction of harmful bacteria such as Escherichia c...
