Problems solved by technology

At present, soluble soybean polysaccharides used in China are mainly dependent on imports, and the price is high, so that many domestic enterprises do not know enough about soluble soybean polysaccharides. Therefore, research on soluble soybean polysaccharides suitable for my country's national conditions can not only solve the environmental problems caused by bean dregs And business problems, can also drive the development of related industries, which is also the development demand of soybean processing

Abstract

The invention belongs to the technical field of polysaccharose extraction and particularly relates to a method for extracting soybean polysaccharose from soybean meal through a biological enzyme method. The method for extracting soybean polysaccharose from the soybean meal through the biological enzyme method comprises the following steps: (1), pretreatment of raw materials; (2), enzymolysis; (3), non water-soluble polysaccharose conversion; (4), centrifugal separation; (5), soluble polysaccharose extraction. After the adoption of zymosis, conditions are mild, enzymolysis to fat and cellulose in the soybean meal is performed by using different enzymes, polysaccharose therein can be extracted, the utilization ratio of the soybean meal is improved, and after the adoption of the method provided by the invention, the soybean polysaccharose obtained is not only high in yield, but also high in purity.

Description

technical field [0001] The invention belongs to the technical field of polysaccharide extraction, and in particular relates to a method for extracting soybean polysaccharide from soybean meal by biological enzyme method. Background technique [0002] The nutritional components of soybean are comprehensive and rich in content, which makes the soybean processing industry in my country and even the world in the ascendant. With the in-depth research on the functional components of soybean, the comprehensive development and utilization value of soybean has attracted more and more attention from all over the world. Functional ingredients such as soybean protein, soybean polypeptide, soybean isoflavones, soybean lecithin and saponins have also been more in-depth research. But bean dregs, the largest by-product of soybean protein processing industry, have been neglected for quite a long time, and the research on it only stays in general application. The poor treatment of bean dreg...
