Fermented soybean meal and production method thereof

Abstract

The invention discloses fermented soybean meal. Based on 100 parts of soybean meal, a fermenting formula comprises the following raw materials of mixed microbial strains, water, an enzyme preparation and a nutritive aid. The invention further discloses a preparation method of the fermented soybean meal. The fermented soybean meal disclosed by the invention has the beneficial effects that according to the fermented soybean meal produced by the method disclosed by the invention, glycinin in the soybean meal can be degraded to 25mg / g or below, beta-conglycinin is degraded to 15mg / g or below, oligosaccharides are completely degraded, trypsin inhibitory factors are degraded to 0.5% or below, the content of lactic acid is 70mg / g or above, and the quality of the fermented soybean meal is obviously improved; and when the fermented soybean meal produced by the method disclosed by the invention is used for feeding animals, digestion and absorption of feeds are facilitated, the digestion and utilization rate of the feeds is increased, the fermented soybean meal can replace animal-derived protein feed raw materials of fish meal and the like, and can wholly or partially replace organic acids and antibiotics, the raising cost is reduced, and economic benefits are increased.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a fermented soybean meal and a production method thereof. Background technique [0002] Soybean meal is a by-product obtained after extracting soybean oil from soybeans. It is one of the most important vegetable protein sources for livestock and poultry. Nutrients have seriously affected the digestion and absorption of nutrients by animals, and at the same time caused problems such as intestinal allergies, diarrhea and even death in young livestock and poultry. Treating soybean meal with microbial fermentation technology can not only eliminate the anti-nutritional components in soybean meal, but also effectively increase the anti-nutritional components in soybean meal. [0003] At present, the treatment methods of solid fermented soybean meal mainly include adding water to the soybean meal and then sterilizing it or heating it to ferment it; However, the use of ...

Problems solved by technology

[0003] At present, the treatment methods of solid fermented soybean meal mainly include adding water to the soybean meal and then sterilizing it or heating it to ferment it; However, the use of the above methods will increase the production cost of sterilization or heating, cause the contamination of bacteria in the fermented soybean meal, increase the drying cost of the fermented soybean meal, and cause the inability of aerobic bacteria to grow in the anaerobic fermentation environment, resulting in unsatisfactory fermentation effect, etc. question
