Abstract

The invention proposes a soybean detoxification method. Soybeans are treated and soaked in a compound microbial bacterial liquid, treated with microwaves, fermented, treated with a passivating agent, steamed with an organic solution, and dried to obtain detoxified soybeans. The invention adopts microwave assistance, and the passivating agent participates in the reaction, thereby passivating the anti-nutritional factors, and the compound microbial liquid is fermented to detoxify, further improving the taste and nutrition of soybeans, chemical solvent + physical steam to remove residual anti-nutritional factors, the method is simple, It can effectively detoxify soybeans without re-initiating toxicity, and can achieve long-term detoxification effect.

Description

technical field [0001] The invention relates to the technical field of agricultural product processing, in particular to a soybean detoxification method and detoxified soybeans. Background technique [0002] Soybeans and soybean products are one of the important foods for Chinese people and play an extremely important role in the prosperity of the Chinese nation. Since the early 1950s, in order to make up for the insufficient supply of food protein nutrition, many countries have vigorously developed soybean protein nutrition as a new protein donor, and widely used and researched it. [0003] According to the book "Technology of Soybean Products" published by China Light Industry Press: There are about 7-10 kinds of trypsin inhibitors in soybeans. So far, two kinds of trypsin inhibitors have been purified by scientists, and there are many others. Trypsin cannot be extracted so far. The heat stability of trypsin inhibitor is very high. When soybeans are heated at 100°C for 6...
