Zymolytic spirit vinasse high-peptide feed and production method thereof

Abstract

The invention relates to zymolytic spirit vinasse high-peptide feed and a production method thereof. The zymolytic spirit vinasse high-peptide feed is prepared by taking fresh spirit vinasse as a base material through the procedures of adding compound enzyme, inoculating bacillus subtilis and brewer's yeast, mixing and then carrying out enzymolysis at preserved temperature, and finally drying. The production method comprises the following steps: A, dosing; B, mixing; C, adjusting the water content; D, carrying out enzymolysis at preserved temperature; and E, drying and preparing the finished product. The compound enzyme is a protease and cellulase compound hydrolytic enzyme preparation. The feed provided by the invention has the advantages that the peptide content of the product accounts for over 50% of crude proteins of the product; as the peptide content is high, the feed is easily absorbed by animals and can be widely applied to various animal formula feed; the spirit vinasse is turned to wealth, so that the additional value of the spirit vinasse is improved. The production method of the zymolytic spirit vinasse high-peptide feed is simple in process, high in efficiency, stable in quality and low in cost.

Description

technical field [0001] The invention relates to an enzymolysis distiller's grain high-peptide feed and a production method thereof, belonging to the technical field of biological enzymolysis. Background of the invention [0002] The annual output of liquor is very large, up to tens of millions of tons, and the by-product of liquor production, distiller's grains (wet), exceeds twice the liquor output. Liquor is fermented from pure grains such as sorghum, corn, wheat, rice, barley or mixed raw materials. Liquor fermentation is mainly to convert the starch in the raw material, and less to convert and utilize the protein component in the raw material, so it is basically stored in the distiller's grains. Due to the concentration of fermentation (raw material starch is utilized), the protein content (dry basis) of distiller's grains can be doubled or more than that of raw materials, reaching about 20%. In addition to the high protein content, the amino acid composition of disti...

AI Technical Summary

Problems solved by technology

The liquid method requires a lot of investment, the product is spray-dried, the purity is high, and the peptide content can reach more than 50%, but the cost is expensive, and it can only be used for high-end food

Solid production input is low, but limited by the viscosity of the peptide, when its content exceeds 5%, the viscosity of the product makes drying difficult and difficult to overcome
