Agricultural byproducts open type yeast solid fermentation method

Abstract

The invention belongs to the bio-fermentation technical field and relates to a method which adopts inoculum open solid fermentation to remove anti-nutritional factor and increase digestibility and nutritive value in agricultural and sideline products such as bean pulp, cottonseed pulp and rapeseed extraction. The product of the invention is suitable for replacing animal albumen in fish breeding and poultry raising and is particularly suitable to be used as juvenile animal. The method includes the following process steps: (a) raw material is prepared (main material: bean pulp, cottonseed pulp and rapeseed extraction, etc.; auxiliary material: peptone, urea, molasses and inoculum); (b) leavening is prepared; (c) controlled fermentation (under temperature control, humidity control and oxygencontrol) is completed with the fermentation temperature ranging from 25 DEG C to 65 DEG C, the humidity ranging from 90 percent to 100 percent and the whole process being semianaerobic; (d) fermentation is stopped; (e) finished product treatment is completed. The method is easy to grasp and has simple and stable process and low cost; moreover, the invention can directly obtain vegetable protein feedstuff raw material which has anti-nutritional factor removed, rich nutrition, easy digestion, rich probiotics and high safety and can replace animal protein sources such as fish meal.

Description

A kind of solid fermentation method of open type koji seeds for agricultural and sideline products Technical field: The invention relates to an open type koji solid fermentation method for eliminating anti-nutrition factors in agricultural and sideline products, improving their digestion and absorption rate and increasing nutritional value, in particular to an open type koji solid fermentation method for agricultural byproducts. Background technique: In the field of aquaculture, feed raw materials, especially protein raw materials, are the basis for the development of the aquaculture industry. With the development of the breeding industry, on the one hand, animal feed protein raw materials are increasingly in short supply, while plant feed protein raw materials are mainly agricultural and sideline products, such as soybean meal, cottonseed meal, rapeseed meal, etc., due to the existence of various anti-nutritional factors, It hinders animals' digestion and absorption of it...
