Embodiment
[0064] This embodiment provides a method for screening the optimal ratio of soybean meal and fermentation broth, which specifically includes the following steps:
[0065] Step S1: Limiting the ratio of soybean meal to fermentation broth
[0066] According to the research of the prior art (CN201810004853-a new type of fermented soybean meal and its preparation process and application), it is known that the fermented soybean meal with better quality will be produced when the weight ratio of soybean meal to fermentation liquid is between 100:45-100:40 . Therefore, in this example, 5 different ratios of soybean meal and fermentation broth (100:45, 100:44, 100:43, 100:42, 100:41) were set up for experiments, in order to screen out the optimum ratio of soybean meal and fermentation broth. Matching.
[0067] Step S2: Production and sampling of fermented soybean meal
[0068] The fermented soybean meal preparation process disclosed in the patent CN201810004853 is used to produce an...

The invention relates to a method for screening an optimal ratio of soybean meal to fermentation liquor. The method comprises the following steps: S1, limiting different weight ratios of the soybean meal to the fermentation liquor; s2, carrying out production and sampling of fermented soybean meal; s3, determining evaluation indexes of the fermented soybean meal, wherein the evaluation indexes arerespectively water, crude protein, crude ash, protein solubility, volatile basic nitrogen, acid-soluble protein based on small peptide and total acid based on lactic acid; s4, calculating the relative value of each index of the fermented soybean meal; s5, analyzing the correlativity of each index of the fermented soybean meal; s6, principal component analysis: utilizing SPSS software to carry outprincipal component analysis on the relative values of seven single indexes of different soybean meal and fermentation liquor proportions, determining the weight of each index, selecting the first three comprehensive indexes, and ignoring the rest indexes; and S7, comprehensively evaluating the quality of fermented soybean meal products under different proportions of the soybean meal and the fermentation liquor by adopting a membership function method so as to screen out the optimal proportion of the soybean meal and the fermentation liquor. The method is simple and efficient.
Description
technical field [0001] The invention belongs to the technical field of feed, and in particular relates to a method for screening the optimum ratio of soybean meal and fermented liquid. Background technique [0002] With the development of breeding and feed industry, the problem of shortage of feed resources has become increasingly prominent. The market demand for high-quality protein feed such as fish meal and bone meal is huge, but the supply is far from sufficient. my country is rich in plant protein sources, among which the output of soybeans is huge, and soybean meal is a by-product of soybean oil extraction from soybeans. Therefore, fermented soybean meal processed and produced with soybean meal as the main raw material has many advantages as a new type of feed. This enzyme can degrade cellulose and protein in raw materials, remove various anti-nutritional factors, improve the nutritional value of soybean meal, reduce the waste of resources, and create huge economic valu...
