Abstract

The invention relates to a method for modifying concentrated soybean protein, which includes the following steps: preparing a concentrated soybean protein solution, preparing an enzyme solution, pumping the concentrated soybean protein solution into a microchannel pulverizer for ultrafine pulverization, and pumping the concentrated soybean protein solution separately from the enzyme solution into the mixing module of the microchannel reactor, the mixed reaction system enters the reaction module for reaction, and then the reaction system flows through the high temperature module to passivate the cellulase and protease activity, and then the obtained reaction system flows through the low temperature module, and finally reacts The system flows out of the microchannel reactor to obtain a modified concentrated soybean protein solution. The invention also relates to the application of the soybean protein concentrate prepared by the aforementioned method in the fields of food and nutrition and health care. The invention has the advantages of fast reaction speed, high output and good product quality.

Description

Technical field [0001] The present invention belongs to the field of soy protein processing, and more particularly to enzyme treatment of soybean concentrated proteins using microchannel pulverization techniques to improve its solubility and improve its flavor characteristics. Background technique [0002] Soy concentrated protein is a high-quality plant protein obtained from most non-protein soluble ingredients with low-temperature bean meal as a raw material, evaporated, demured, pulverized. The protein content of concentrated protein obtained by alcohol leaching method is high, can reach 70%. However, due to a large amount of ethanol using a large amount of ethanol during processing, the protein molecular structure has changed, and the nitrogen dissolution index (NSI) value is low, affecting its application in the food industry. In addition to proteins, soy-concentrated proteins also contain about 20% (dry base) carbohydrates, wherein insoluble polysaccharides can reach around...
