Method for preparing high protein feed by tea leaves and its product

Abstract

The invention relates to a method for preparing high protein feed by tea leaves, which is characterized by comprising the following steps: drying and crushing the tea leaves to obtain solid state substance; 2) burdening the solid state substance and water according to weight ratio of 1:3 to 1:5, mixing to obtain a mixture, wherein the pH value of the mixture is controlled at 4.5-6.0; 3) performing disinfection to the mixture prepared in the step 2); 4) inoculating the mixture after the disinfection by bacterial classification according to 10%-20% of inoculation amount, wherein the fermentation condition is characterized in that the pressure is normal pressure, the temperature is 30-37 DEG C, the fermentation period is 4-7 days; and 5) drying after fermentation to obtain the high protein feed. According to the invention, the waste tea leaves can be fully used, so that the pollution of the waste tea leaves on environment can be reduced, and feed with low cost can be provided for livestock and poultry. According to the invention, the process is simple, the production cycle is short, and the preparation method is in favor of industrial production. The produce has the advantages of no pollution, less toxic and side effect, high protein content and low cellulose content.

Description

technical field [0001] The invention relates to the field of feed processing, in particular to a preparation method of high-protein feed. Background technique [0002] There are two main sources of tea residue in my country: one is the tea residue formed after the industrial extraction of tea polyphenols and other biochemical components; the other is the tea residue formed in the tea beverage industry. The comprehensive utilization of biomass such as medicinal dregs is a worldwide problem. At present, most of the domestic medicinal dregs are landfilled, and a small part is used as feed and fertilizer, which causes serious environmental problems such as sewage and odor. The other part of the medicinal dregs is dangerous. Waste, the state has separate regulations on hazardous waste treatment, and the requirements are relatively strict. [0003] The tea dregs formed by the beverage industry are rich in nutrients. Tea dregs (instant tea dregs) refer to the residue after extrac...
