Abstract

The invention discloses a method for producing a seaweed protein feed through the synergistic effect of enzymolysis and fermentation. The method comprises the steps of fully mixing seaweed residue (the water content is 38%) and a feed enzyme preparation according to a certain proportion and performing the enzymolysis for 4-7h with the pH of 6.2-7.0 at the temperature being 35-45 DEG C to obtain a seaweed residue-feed enzyme preparation mixture; inoculating compound microorganisms and performing solid fermentation. The method has a simple process and is easy to operate; an external source is added to degrade a cellulose preparation to produce nutrition beneficial to microbial growth through the enzymolysis and make up the deficiency of enzyme produced by using the compound microorganisms, so as to stabilize the solid fermentation process and the product quality, greatly reduce the content of cellulose and increase the protein content; the seaweed protein feed is rich in multiple minerals, bioactive constituents and unknown somatomedin, and can be used as a protein feed for livestock and poultry and an aquatic feed; the method provides a technical support for growing tensions on developing novel protein resources and relieving a feed protein source.

Description

technical field [0001] The invention belongs to the field of feed protein source production, and in particular relates to a method for synergistically producing biological seaweed protein feed through enzymolysis and fermentation. Background technique [0002] The current shortage of high-quality feed is a well-known objective reality. The demand for protein feed resources in my country is increasing and the dependence on foreign countries is increasing year by year. The shortage of feed protein raw materials has made the problems of my country's feed industry and aquaculture industry, especially aquaculture industry, increasingly prominent. The development and utilization of new feed protein sources and unconventional animal and plant protein feeds is undoubtedly a good strategy to alleviate the shortage of protein feed resources and reduce costs. Therefore, the high-efficiency conversion and utilization technology of protein feed resources based on microbial fermentation ...
