A kind of green brick tea stack fermentation strain composition and application

Abstract

The invention provides a bacterial strain composition for stack fermentation of green brick tea, which belongs to the technical field of microbial strains. The strain composition of green brick tea stack fermentation includes Bacillus subtilis and Aspergillus fumigatus, wherein, the Bacillus subtilis is preserved in China Center for Type Culture Collection, and the preservation number is: CCTCC M 2018288; the Aspergillus fumigatus is preserved in China Typical Culture Collection Center, the collection number is: CCTCC M 2018287. The present invention uses two strains of Bacillus subtilis and Aspergillus fumigatus to carry out pure-bred composting fermentation, not only the product components are the same as the traditional open composting fermentation, but also the flavor is the same, which is different from the natural composting process of microorganisms in the traditional open utilization environment. Compared with this method, the time can be shortened by about 4 weeks, and it is not easy to be contaminated by bacteria, which is conducive to increasing corporate benefits, improving and stabilizing product quality.

Description

technical field [0001] The invention belongs to the technical field of green brick tea fermentation, and in particular relates to a composition and application of green brick tea fermenting strains. Background technique [0002] Green brick tea belongs to black tea, which is a kind of post-fermented tea. It uses dried old green tea as raw material, which is naturally fermented and pressed. It is mainly produced in the Xianning area of ​​Hubei Province and has a production history of more than 100 years. Green brick tea has the functions of eliminating greasiness, reducing fat and losing weight, supplementing vitamins, etc., and can eliminate the health threats caused by the special eating habits of ethnic minorities in the frontier. For a long period of time, green brick tea has been a "policy commodity, fixed-point production, unified purchase and marketing", and an indispensable daily necessities for ethnic minorities in the frontier. [0003] Heaping is the key process ...

AI Technical Summary

Problems solved by technology

At present, there is no report on the isolation of Aspergillus fumigatus from Pu-erh tea pile fermentation, and the use of Aspergillus fumigatus in the fermentation and processing of green brick tea, and there is no report that only two strains can be used to eliminate the main components of sun-dried green tea within a week. Content of quality ingredients fermented to ideal Odui tea-like levels
