Problems solved by technology
Generally, they can be divided into three categories: physical methods, chemical methods and microbial treatment methods. From the perspective of the final treatment effect, physical methods need to consume a lot of manpower and material resources, and the detoxification effect is not obvious; chemical methods have drug residues. problems, thereby affecting the final product application

example 5
[0014] Example 5: Directly use the rapeseed meal after the production of oil as the raw material, add such as sterilized water to the rapeseed meal, so that the weight ratio of the rapeseed meal raw material to feed water is 1:0.8; The percentage of the weight or volume of the culture medium and the weight of the rapeseed raw material is respectively 2% of Bacillus subtilis, 2% of Bacillus cereus, and 1% of Lactobacillus casei; the fermentation temperature is 30°C-50°C, and the fermentation time is 64 hours.
[0015] Among them, rapeseed meal without any fermentation treatment was used as a control.

The invention discloses a method for producing virus-free rapeseed meal by adopting a biological fermentation method. The method comprises the following steps of: a, adding material water into a rapeseed meal raw material; b, inoculating bacillus subtilis, bacillus cereus and lactobacillus casei into the rapeseed meal; c, fermenting at the controlled temperature between 30 DEG C and 50 DEG C; and d, at the end of the step c, drying the fermented rapeseed meal, grinding, inspecting and packaging. The method disclosed by the invention is easy to operate. By adopting the method, a complex process and a harsh condition are not required, batch production is available and the cost problem can be solved.
Description
technical field [0001] The invention relates to a method for removing anti-nutritional factors in rapeseed meal by using a microbial mixed fermentation method, especially a method for removing glucosinolates, belonging to the technical field of biological fermentation, and its products can effectively degrade glucosinolates in rapeseed meal after biological fermentation, and improve The protein content of rapeseed meal is degraded into small molecular peptides, thereby effectively improving the protein quality of rapeseed meal and the utilization rate in various livestock and poultry feeds. Background technique [0002] Rapeseed meal is rich in protein and is a good protein source for animal feed. However, because it contains a variety of toxic or anti-nutritional substances, such as glucosinolates, tannins, sinapinic acid, etc., its utilization value and usage are greatly limited. For this reason, relevant researchers at home and abroad have carried out extensive and in-de...
