Embodiment 1

[0026] The equipment mainly used in the process of preparing fermented soybean meal by the simultaneous solid fermentation and enzymatic hydrolysis method includes: pulverizer, mixer, conveyor belt, batching scale, seed cultivation tank, fermentation tank, dryer, etc. and other supporting equipment. The specific steps of the process are:

[0027] (1) Seed preparation: Prepare seed medium with bran and soybean meal, insert KD1 commercial strain, and cultivate at 30-37°C for 48 hours, and the ratio of bran to soybean meal in the seed medium is 6:4.

[0028] (2) Ratio of fermented materials: Taking the quality of soybean meal as a reference, the fermented materials are blended according to the following proportions: protease 5%; molasses 4%; acetic acid 0.5%;

[0029] (3) Mixing of materials: Mix the seeds with the fermented raw materials at an inoculum amount of 3%, and the mixing uniformity of the materials is required to be greater than 95%; adjust the water content of the mat...

Abstract

The invention provides a novel production process of fermented soybean meal by synchronous solid fermentation and enzymolysis. The process increases feeding value of the soybean meal by synchronization of probiotic fermentation and protease enzymolysis and mainly includes: high molecular weight protein is degraded into small molecular weight protein, polypeptide, small peptide and the like easy to absorb by animals by enzymolysis of an external added protease and microbial secretion composite enzyme system; and antinutritional factors in the soybean meal are removed by microbial fermentation, content of organic acids and microbes in the fermented soybean meal is increased, and accordingly feeding value of the soybean meal is increased. The fermented soybean meal produced by the production process is rich in various digestive enzymes, most of the antinutritional factors in the soybean meal are degraded, content of soluble protein in the soybean meal is increased, a certain amount of organic acids and special flavor is added, the soybean meal has high feeding value and is applicable to livestock and poultry feed and aquatic feed, and the soybean meal serving as the aquatic feed is capable of partially replacing fish meal in application.

Description

technical field [0001] This article relates to a new process for preparing fermented soybean meal by simultaneous solid fermentation and enzymatic hydrolysis, which is a production method for improving the feeding value of soybean meal by using biotechnology, and belongs to the field of feed production. Background technique [0002] Protein raw materials are the foundation of the development of the feed industry. The shortage and high price of protein raw materials in my country have become one of the bottlenecks in the development of animal husbandry and aquaculture. At present, with the improvement of people's living standards and the emphasis on quality of life, the demand for meat, eggs, and milk is increasing. The production of food and feed is facing severe challenges, and feed protein resources are scarce. It is imminent to improve the conversion efficiency of grain to animal husbandry products and the utilization rate of feed, broaden feed resources, and develop unco...
