A kind of fermentation enzymolysis agent and application thereof for soybean meal fermentation

Abstract

The invention provides a fermenting enzymolysis agent for soybean meal fermentation and application thereof and belongs to the technical field of feed fermenting agents. The fermenting enzymolysis agent consists of microorganism strains, enzyme preparations, an accessory ingredient and a carrier. According to the fermenting enzymolysis agent, seven types of beneficial bacteria and three types of enzyme preparations are combined, 72-hour aerobiotic, microaerobic and anaerobic fermentation and enzymolysis are performed on crushed soybean meal and a small amount of corn flour, so that antinutritional factors in the soybean meal are eliminated, cell walls are broken, non-protein nitrogen is converted into mycoprotein, proteins are decomposed into polypeptide and small peptide, more Vitamin B is generated, the nutrition performance of the soybean meal is comprehensively improved, and thus the soybean meal becomes a feed protein source capable of partially replacing a feed protein source for import fish meal feed.

Description

technical field [0001] The invention belongs to the technical field of feed starters, and in particular relates to a fermentation enzymolysis agent for soybean meal fermentation and an application thereof. Background technique [0002] my country is a big aquaculture country, which has led to a huge demand for aquatic feed. The output of aquatic feed in my country accounts for more than 60% of the world's total. Fishmeal occupies a large proportion in the composition of aquatic feed, especially the proportion of fishmeal in the feed of some special aquatic products is as high as 50%, which makes my country the largest consumer of fishmeal. According to relevant statistics, in 2011, my country consumed about 1.45-1.5 million tons of fishmeal, of which 1.2 million tons depended on imports, accounting for about 80% of the total. With the improvement of people's living standards in our country, the demand for aquatic products is increasing day by day. With the transformation of...

Problems solved by technology

[0003] Soybean meal is a by-product produced by extracting soybean oil from soybeans by extraction process. Compared with other vegetable proteins, it has high protein content (up to 42-48%), excellent amino acid structure, high digestibility and good palatability. Good characteristics, but there are still big differences compared with fish meal, the outstanding point is that the digestibility is low (fish meal is about 95%, soybean meal is only about 82%), the main reason is that there are anti-nutritional factors such as trypsin inhibitor in soybean meal The disadvantage of indigestibility caused by the common cell wall composition characteristics of factor and vegetable protein

[0004] The advantages of soybean meal make it the most likely substitute for fishmeal, but its disadvantages prevent it from being a direct replacement
