Abstract

The invention discloses a method for preparing feed raw materials by solid state fermentation of tea dregs, and relates to the field of feed processing. The method is as follows: mixing tea dregs, bean pulp, bran, molasses and composite trace elements as fermentation substrate according to a certain mass ratio, adjusting water content, adding 4 kinds of bacteria such as bacillus subtilis, saccharomyces cerevisiae, aspergillus niger and lactic acid bacteria, controlling fermentation conditions, and performing enzymolysis and aerobic and anaerobic combined fermentation to obtain the product. According to the tea dreg solid state fermentation feed produced by the method of the invention, the method effectively reduces the crude fiber content of the tea dregs, improves the protein content, andis suitable for industrial production of feeds.

Description

technical field [0001] The invention relates to the field of feed, in particular to a method for preparing feed raw materials by solid-state fermentation of tea dregs. Background technique [0002] The area of ​​my country's tea gardens has reached 40 million mu. With the surge in tea production and the extension of the industrial chain, a large number of tea deep-processing enterprises have emerged. However, during the production of tea beverages, tea foods, and the extraction of active ingredients, tea leaves will produce more than 70% of the tea dregs. Because the tea dregs have a high water content (70% to 80%), they contain a large amount of soluble nutrients. It is easy to breed a large number of microorganisms and cause environmental problems. Studies have shown that tea dregs contain 17% to 19% crude protein, 16% to 18% crude fiber, 1% to 2% tea polyphenols, 0.1% to 0.3% % caffeine, and the proportions of lysine and methionine in the amino acids that make up protein...
