Abstract

The invention discloses a preparation method of debitterized high-temperature soybean meal peptide powder capable of promoting calcium absorption, and belongs to the technical field of processing of novel soybean meal peptide powder. The technology comprises specific steps of (1) performing high-temperature soybean meal pretreatment; (2) performing efflux cavitation treatment; (3) performing enzymolysis through complex enzymes of Alcalase2.4L enzymes and actinomucor elegans benjam. et hesseit. protease; (4) adding OPO structure lipids; (5) performing embedding through beta-cyclodextrin; and (6) performing vacuum freeze drying. According to the preparation method disclosed by the invention, high temperature soybean meal is used as a raw material, an efflux cavitation assisted enzymolysis technique is combined with a polysaccharide embedding and concealing method, and high temperature soybean meal peptide powder which is low in bitterness and capable of calcium absorption by the intestine and the stomach is prepared, so that development in pluralism of the high temperature soybean meal is realized, and resources are in transposition; and besides, the enzymolysis is performed througha compound enzyme preparation, so that the efficiency is high, and industrial production of the debitterized high-temperature soybean meal peptide powder is facilitated.

Description

[0001] The invention belongs to the technical field of novel soybean meal peptide powder processing, and mainly relates to a preparation method of high-temperature soybean meal peptide powder for debittering and promoting calcium absorption. Background technique [0002] High-temperature soybean meal is a by-product obtained by high-temperature desolventization after soaking in soybean oil, with a protein content of 40-45%, an oligosaccharide content of 10-15%, and a polysaccharide and cellulose content of 20-25%. Develop and exploit value. my country's soybean meal production has grown rapidly, with a compound annual growth rate of about 10%. In 2015, the soybean meal production was 61.2 million tons, accounting for about 26.92% of the world's soybean meal production. More than 95% of them are high-temperature soybean meal, and the average price is 3600 yuan / ton. The application prospect of high-temperature soybean meal is huge. Peptide powder is the protein with the most co...
