Method for producing high-protein-content feed by fermenting soy sauce residues utilizing EM bacterium liquid

Abstract

The invention discloses a method for producing a high-protein-content feed by fermenting soy sauce residues using EM bacterium liquid. A low-temperature continuous-phase-change extraction technology is adopted in the method for producing the high-protein-content feed by fermenting soy sauce residues using the EM bacterium liquid so as to perform deoiling and desalting treatments on the soy sauce residues, and thus, massed substances including cellulose, ptoteins and so on, are scattered so that salt content of the soy sauce residues is reduced so as to facilitate fermentation; the salt contentof the soy sauce residues is further reduced after fermentation with cellulase, and crude fiber content of the soy sauce residues is also reduced so as to allow relative content increase of proteins;and then, fermentation and degradation treatments are performed on a mixed base material under double effects of EM bacterium liquid and corynebacterium glutamicum so that nutrient complementation isrealized so as to improve content ratio of the proteins and the amino acids in the feed; moreover, the corynebacterium glutamicum capable of producing amino acids is inoculated so as to increase amino acid content of the feed.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, and specifically relates to a method for producing high-protein feed by using EM bacterial liquid to ferment soy sauce residue. Background technique [0002] As the waste residue of soy sauce production-the output of soy sauce residue is also very large. Many soy sauces use soybeans, wheat or flour as raw materials. During the fermentation process of making soy sauce raw materials, except for the protein and starch in the raw materials are partially utilized, other nutrients, such as oil, fiber, phospholipids, etc., are mostly left in the soy sauce residue In, therefore, the soy sauce residue is rich in nutrients as animal feed. The salt content in the soy sauce dregs is high, and the untreated soy sauce dregs are used as animal feed, which has poor palatability and can easily cause salt poisoning. In mild cases, food intake will drop sharply, weight loss, and in severe cases, a...

AI Technical Summary

Problems solved by technology

The salt content in soy sauce dregs is relatively high. If untreated soy sauce dregs are used as animal feed, their palatability is poor, and it is very easy to cause salt poisoning. In mild cases, food intake will drop sharply, weight loss, and in severe cases, animals will die

Therefore, in the prior art, when the soy sauce residue is used to make animal feed, the soy sauce residue must be desalinated, but due to the poor desalination effect, it is difficult to use the soy sauce residue as a raw material for animal feed in large quantities

Directly used as feed may cause problems such as salt poisoning and low absorption efficiency of poultry and livestock
