Detoxifying agent for cottonseed meal and rapeseed meal as well as preparation method thereof and preparation method of microorganism feed prepared by detoxifying agent

Abstract

The invention discloses a detoxifying agent for cottonseed meal and rapeseed meal as well as a preparation method thereof and a preparation method of a microorganism feed prepared by the detoxifying agent, wherein the detoxifying agent is prepared from the following raw materials: mixed bacterial liquid, oligofructose, glucose, edible salt and softened water; the mixed bacterial liquid is prepared from the mixture of soluble phosphine bacteria, bifidobacterium and lactobacillus acidophilus. The preparation method comprises the following steps of mixing, fermentation, temperature reduction andfermentation again, thus the finished product can be packaged. Because the technical scheme is adopted, the detoxifying agent provided by the invention has the detoxifying effect of 76-97% on a rapeseed pancake, and removes most anti-nutritional factors; the products after detoxification have good adaptability to animals and have special flavor, the product protein after fermentation and detoxification can be improved by 8-12%, meanwhile vitamin and digestive enzyme are also rich, and the amino acid utilization ratio is improved by 11.9%. According to the invention, the process is simple, theflow is short, the investment is less, and environment pollution is not generated.

Description

Technical field [0001] The present invention involves use microorganisms to decult the cotton meal and rapeseed meal, which involves a dehydent and preparation method for cotton meal and rapeseed meal.method. Background technique [0002] my country's cotton meal and rapeseed meal have an annual output of more than 6 million tons, and their protein content is between 30 and 47%, which is an important protein resource.However, because cotton meal contains glycol and pesticide residues, rapeseed cakes contain toxins and anti -nutritional factors such as glucosolin and agricultural residues. In addition, the quality of the protein is poor and the lysine content is low.Very easy to apply.Because these resources cannot be effectively used every year, it has caused great waste to the country. [0003] The number of cottonseed cotton cotton cotton meal, rapeseed cakes, and rapeseed meal are large. Its crude protein content is 36-41 %, and the total amino acids in crude protein are 83-87...

AI Technical Summary

Problems solved by technology

However, because cottonseed cake cottonseed meal contains toxic substances such as free gossypol and cycloacrylic acid, glucosinolates, isothiocyanates, oxazolidinethiones, phytic acid, tannins, sinapine, Saponin and other toxic substances and anti-nutritional factors exist, which are toxic to livestock and poultry, and because the hulls are not removed during oil processing, the crude fiber content in cottonseed cake cotton meal and rapeseed cake meal is relatively high, and the palatability is poor etc., so that its use is greatly limited

[0004] At present, the detoxification methods used at home and abroad are mainly physical and chemical methods, but generally cannot be effectively detoxified, and will cause secondary pollution or solvent residues
