Problems solved by technology

[0005] However, the free gossypol contained in cottonseed meal has adverse effects on the digestion, absorption, and metabolism of nutrients in poultry and livestock, as well as the health and production performance of animals, leading to growth retardation, poisoning, and death of animals, which restricts the use of cottonseed meal in poultry and livestock. Feed and aquafeed applications
At present, the removal methods of gossypol in cottonseed meal include ferrous sulfate detoxification method, oxidant detoxification method, etc. These methods all have shortcomings such as excessive equipment investment and loss of nutrients. Low and the problems encountered in detoxification, improve its nutritional value and applicability, realize the comprehensive utilization of cotton meal, research and development of a new method of removal of gossypol in cotton meal is of great significance

Abstract

The invention relates to a preparation method of novel insect fermented cottonseed meal protein and belongs to the technical field of biological fermentation. According to the method, cottonseed meal is used as a raw material and is mixed with beneficial microorganism bacterium liquids including lactobacillus, bacillus and the like to form a mixture; then young engineering fly maggots are uniformly spread on the surface of the mixture to carry out insect fermentation for 105-120 hours; and the obtained product is dried and crushed to obtain the insect fermented cottonseed meal protein. By adopting the method, toxins (free gossypol) in cottonseed meal can be effectively removed and the detoxification rate is more than or equal to 80%; probiotics including the lactobacillus and the like are added so that the palatability is improved and the palatability, even the palatability better than the soya bean meal is achieved; the insect fermented cottonseed meal protein can be remarkably degraded and concentrated and the protein quality of common cottonseed meal is improved; the content of the gossypol in the treated insect fermented cottonseed meal is effectively reduced; and meanwhile, the content of the protein is improved, can reach 52%-55% and is higher than the protein content of the common cottonseed meal.

Description

technical field [0001] The invention relates to a method for preparing cotton meal protein, in particular to a method for preparing novel insect-fermented cotton meal protein, and belongs to the technical field of biological fermentation. Background technique [0002] Feed protein can be divided into animal protein and plant protein according to the source of raw materials. my country is a country that lacks animal protein resources such as fish meal, especially high-quality fish meal mainly depends on imports. Therefore, people are paying more and more attention to plant protein. The application of protein raw materials. Vegetable protein sources include soybean meal, rapeseed meal, cotton meal, peanut meal, etc., with low prices and wide sources. [0003] Cottonseed meal is a cake obtained from cottonseed after oil is squeezed out, and most of the residual oil inside is separated through leaching process to obtain a reddish or yellow granular product, which is the main raw...
