Method for preparing flavor protein feed from compound bacteria fermentation distiller's grains

Abstract

The invention belongs to the technical field of animal food or feed processing and particularly relates to a method for preparing a flavor protein feed from compound bacteria fermentation distiller's grains. The method comprises the steps of carrying out gas explosion on distiller's grains and carrying out ultrasonic cooperative treatment on broken lignin and cellulose, and then inoculating phanerochaete chrysosporium and trichoderma viride; inoculating candida utilis and wickerhamomyces anomalus on the basis of a degradation product; and finally adding yellow water generated in white spirit production to the fermented feed to prepare a pellet feed. According to the method for preparing the flavor protein feed from the compound bacteria fermentation distillers' grains, the crude fiber content is reduced, the protein content is improved, the flavor is added, the palatability and the security are improved, the environmental pollution of the distiller's grains and the yellow water is reduced, wastes are changed into treasure and the method has significant environmental benefits.

Description

technical field [0001] The invention belongs to the technical field of animal food or feed processing, and in particular relates to a method for preparing flavored protein feed by fermenting distiller's grains with compound strains. Background technique [0002] As a country with a large population and a large animal husbandry industry, the problem of human and animal competition for food is becoming more and more serious, which affects the development of the entire animal husbandry industry and makes the animal husbandry industry face a serious shortage of feed resources, especially the shortage of protein feed resources. According to statistics, my country lacks at least 15 million tons of protein feed every year. The current solution is mainly to import foreign protein feed raw materials or make high-priced protein feed, which seriously restricts the development of my country's animal husbandry. In the process of developing protein feed, liquor distiller's grains are chea...

Problems solved by technology

In the process of feed development, according to the traditional feed fermentation technology, the flat open tank fermentation or stack fermentation is usually adopted, but these fermentation processes require a large-area fermentation workshop, the fermentation efficiency is low, and a large amount of time is occupied. land, it is difficult to achieve industrialization and large-scale production; in addition, according to research reports, the average annual loss of food and feed in the world is about 20% of the total output, and more than half of it is caused by mildew, so in the traditional feed production process Corresponding chemical antifungal agents are often added, but it is easy to affect the quality of livestock and poultry products, and it will also increase the risk of drug resistance of pathogenic microorganisms in livestock and poultry
