Problems solved by technology

The high content of high polysaccharides and anti-nutritional factors limits the further improvement of the protein quality of fermented soybean meal, resulting in a crude protein limit of only about 50% in fermented soybean meal prepared by traditional fermentation methods
[0004] Therefore, it is very important to improve the preparation method of fermented soybean meal and solve the problem that the content of polysaccharides and anti-nutritional factors in fermented soybean meal is too high and the quality of crude protein is difficult to improve

[0052] (1) Preparation of Aspergillus niger liquid

[0053] A. Inoculate Aspergillus niger into the Aspergillus niger slant culture medium, and cultivate at 25~30°C for 68~76h; pick a ring of Aspergillus niger from the Aspergillus niger slant medium, and inoculate it into the Aspergillus niger liquid medium , cultured at 23-28°C for 72-96 hours to obtain Aspergillus niger enrichment liquid;

[0054] B, get the aspergillus niger enrichment liquid prepared by step A, inoculate the aspergillus niger liquid culture medium with the inoculum size of 0.5~5:100 by volume ratio, adjust the pH to 6.2~6.6, ventilate under 23~28 ℃ ( The air after the filter bacteria treatment) was cultivated for 72-96 hours; after that, each inoculation was inoculated into the Aspergillus niger liquid medium according to the volume ratio of 0.5-5:100, and the pH was adjusted to 6.2-6.6, 23-28 Cultivate for 72-96 hours with aeration (air after filter bacteria treatment) at ℃, until it expands to 5L.

Abstract

The invention discloses a preparation method of fermented soybean meal for feeding. The preparation method includes inoculating mixed bacteria solution into fermented soybean meal substrate and uniformly mixing; fermenting for 72 to 96 hours at 27-37 degrees Centigrade; drying and smashing to obtain fermented soybean meal for feeding. The mixed bacteria solution is composed of aspergillus niger liquid, saccharomycetes liquid, bacillus subtilis liquid and lactic acid bacteria liquid. The weight ratio of the mixed bacteria solution to the fermented soybean meal substrate is 6-18:1000, and the weight ratio of aspergillus niger liquid, saccharomycetes liquid, bacillus subtilis liquid and lactic acid bacteria liquid is 1-4:0.5-2:0.5-2:0.5-2. By the preparation method, polysaccharide in the fermented soybean meal can be effectively degraded, nutrient substance in the soybean meal is released, and crude protein of the fermented soybean meal is concentrated. Meanwhile, antinutritional factors such as glycinin, beta-conglycinin, oligosaccharide and phytic acid are effectively degraded, digestive utilization rate of nutrients is increased, and the key problems that glycan content in the fermented soybean meal is high and crude protein is hard to improve and poor in nutritive value are solved.

Description

technical field [0001] The invention belongs to the technical field of fermentation, in particular to a method for preparing fermented soybean meal for feeding. Background technique [0002] Due to its good nutritional value, soybean meal is currently the most widely used vegetable protein raw material in the feed industry, but there are many anti-nutritional factors in it, which limits its further development and application. At present, the method of microbial fermentation is mostly used to improve the quality of soybean meal, mainly using bacterial fermentation to process soybean meal, and the processed soybean meal removes some polysaccharides, glycinin, β-conglycinin, oligosaccharides, phytic acid and other antioxidants. Nutritional factors increase the crude protein content slightly, and are rich in protease, amylase, organic acid and active probiotics, making soybean meal into functional feed with high nutritional value. [0003] However, fermented soybean meal prepa...
