Method for preparing fermented tea, fermented tea prepared by using method, and application of fermented tea

Abstract

The invention provides a method for preparing fermented tea, fermented tea prepared by using the method, and application of the fermented tea. The method comprises the following steps: (1) providing primary seeds of rasamsonia emersonii, wherein the primary seeds are a strain, which is not cultured by any tea culture medium, of the rasamsonia emersonii; (2) inoculating the primary seeds of the rasamsonia emersonii in a sterilized tea culture medium for culturing under the sterile conditions so as to provide secondary seeds of the rasamsonia emersonii; (3) enabling the secondary seeds of the rasamsonia emersonii to grow and be fermented under the sterile conditions for 15-25 days at 40-54 DEG C in a fermentation tea culture medium having a water content of 41-72wt% based on the dry weight of tea leaves so as to obtain the fermented tea. According to the method provided by the invention, fermentation is more stable and safer, and is short in fermentation cycle and full in material conversion.

Description

technical field [0001] The invention belongs to the field of tea processing, and in particular relates to a method for preparing fermented tea, fermented tea prepared by the method and application thereof. Background technique [0002] The pile fermentation of fully fermented tea such as Yunnan Pu'er cooked tea, Hunan dark tea, Guangxi Liubao tea, etc. is inoculated naturally by the microorganisms that come with the raw tea and the microorganisms in the fermentation environment; there are many kinds of microorganisms involved in the fermentation process, which can be detected and separated. There are more than a hundred kinds of microorganisms, and there are too many ineffective bacteria; the temperature and humidity of the fermentation process are greatly affected by the environment, and it is difficult to control the fermentation conditions; ensure. For example, fermented tea such as Pu'er cooked tea has many health benefits, but none of them are obvious or unstable. The ...

AI Technical Summary

Problems solved by technology

[0002] The pile fermentation of fully fermented teas such as Yunnan Pu'er cooked tea, Hunan black tea, and Guangxi Liubao tea is all based on the natural inoculation of the microorganisms in the raw tea and the microorganisms in the fermentation environment; a variety of microorganisms participate in the fermentation process, which can be detected and separated. There are more than a hundred kinds of microorganisms, and there are too many ineffective bacteria; the temperature and humidity of the fermentation process are greatly affected by the environment, and it is difficult to control the fermentation conditions; the fermentation process is complicated, and it belongs to empirical fermentation, and the stability of tea quality is difficult ensure

For example, fermented tea such as Pu'er cooked tea has many health benefits, but none of them are obvious or unstable. The in-depth development of fermented tea requires a variety of fermented tea raw materials with stable ingredients and obvious efficacy characteristics
