Method for deeply fermenting soybean meal by virtue of compound phytase and glucose oxidase

Abstract

The invention discloses a method for deeply fermenting soybean meal by virtue of compound phytase and glucose oxidase. The method comprises the following steps: (1) respectively inoculating lactic acid bacteria, bacillus subtilis and saccharomycetes into different liquid fermentation tanks, and fermenting for 18 hours; (2) adding phytase and glucose oxidase into prepared bacteria solutions; (3) spraying the bacteria solutions into the soybean meal, controlling moisture, uniformly stirring, and continuously fermenting for 72 hours; (4) drying, grinding, weighing, packaging and storing fermented materials. Preferably, the configuration proportion of lactic acid bacteria to bacillus subtilis to saccharomycetes is 100 to 1 to 10; and the specifications of phytase and glucose oxidase are respectively 250U / kg-350U / kg and 150U / kg-250U / kg, and the proportion is 1 to (0.6-0.8). The method has the beneficial effects that the utilization ratio of phytate phosphorus in the soybean meal is increased, the phosphorus resource is saved, the environmental pollution is reduced, the mycotoxins such as aspergillus flavus are degraded, escherichia coli and salmonella in animal intestines are inhibited, and the production properties of beasts and birds are improved.

Description

technical field [0001] The invention relates to a method for deeply fermenting soybean meal with compound phytase and glucose oxidase, which belongs to the technical field of biological mold decomposition and fermentation. Specifically, it improves the utilization rate of phosphorus element through phytase and strengthens the anti-toxic bacteria through glucose oxidase. suppression. Background technique [0002] my country is one of the largest breeding countries in the world. With the development of animal husbandry, the breeding industry is gradually becoming industrialized and large-scale, accompanied by the vigorous development of the feed industry, and the production and sales of feed are increasing year by year. One of the most important vegetable protein sources in the world, its crude protein content is as high as 43% to 48%. As a high-quality bio-fermented protein raw material, fermented soybean meal utilizes plant-based protein to solve the problems of digestion an...

Problems solved by technology

[0003] However, the current fermented soybean meal uses lactic acid bacteria, Bacillus subtilis and yeast for collaborative fermentation, but they failed to degrade and eliminate phytate phosphorus and mycotoxins during the fermentation process, resulting in low utilization of phytate phosphorus. Moreover, the feed raw materials are susceptible to mold contamination during production and transportation, which affects the palatability and feed intake of piglets.
