Yeast protein feed using spirit-based distillers' grains as base material and production method thereof

Abstract

The invention relates to a yeast protein feed using spirit-based distillers' grains as base material and a production method thereof. The yeast protein feed uses the spirit-based distillers' grains as the base material, materials for fermentation culture are added and comprise enzyme preparation used for fermentation of the distillers' grains, yeast inoculant and nutrition auxiliary materials for heat preservation culture after being mixed, and finally the product is prepared by drying. The product per gram contains 2-5 billion yeasts. The invention has the advantages that the production method is a production method of microecological feed with no pollution. The feed can improve the digestive absorption of livestock and poultry for the nutrient substances, improves the digestive function, promotes the production performance of the livestock and poultry and enhances the immunity; meanwhile, the feed also improves the nutritional value of the spirit-based distillers' grains and becomes the novel protein feed which turn waste into wealth.

Description

technical field [0001] The invention relates to a yeast protein feed based on distiller's grains and a production method thereof, belonging to the technical field of yeast cell solid-state fermentation. Background technique [0002] my country's liquor annual output is about several million tons, and the by-product of liquor production-distiller's grains (wet) exceeds ten million tons. 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 components in the raw material, which are basically preserved in the distiller's grains. Due to the concentration of fermentation (the raw material starch is utilized), the protein content (dry basis) of distiller's grains can be doubled or more than that of the raw material, reaching about 20%. In addition to the high protein content, the amino acid composition of distiller...

Problems solved by technology

Many products (such as Yikang X P, Yea Sail, etc.) have entered the market, but the existing technology uses a large amount of soybean protein, fish meal protein, etc. to produce feed, and the price is very expensive

Due to many difficulties in the production of yeast feed protein from distiller's grains, it is difficult to obtain good products. For a long time, there has been no successful example of using distiller's grains to produce yeast feed protein
