Abstract

The invention discloses a Pu'er tea fermentation method by directly adding a solid strain and a carbon source. The Pu'er tea fermentation method is characterized by comprising the following steps: (1)weighing dry tea, (2) uniformly spreading the dry tea on a sieve tray, and carrying out airing treatment, (3) preparing a certain proportion of a fermentation spray liquid, wherein the fermentation spray liquid is prepared from the following raw materials: solid strains, aspergillus niger and a carbon source, (4) spraying the fermentation spray liquid prepared in the step (3) to tea obtained by the step (2), and controlling a fermentation environment, (5) carrying out drying treatment, (6) carrying out sterilization treatment and (7) carrying out packaging treatment. According to the Pu'er tea fermentation method, the large-scale production of Pu'er tea is facilitated, dominant strains and tea product appearance controllability are achieved, and food safety is improved and perfected. Thefermentation time is shortened, the production cost and the labor force are reduced, and the appearance guarantee period of the finished product is 3 years or above longer than that of the finished product obtained by the traditional fermentation method.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a Pu'er tea fermentation method by directly adding solid strains and carbon sources. Background technique [0002] The traditional Pu-erh tea fermentation method involves repeated turning of the pile in the middle, making it difficult to control the temperature and humidity; the strains are complex and the quality of the finished product is uncontrollable. Contents of the invention [0003] The purpose of the present invention is to provide a method for directly adding solid strains and carbon source Pu-erh tea fermentation, simplifying the Pu-erh tea fermentation process, and improving quality control; solving the traditional Pu-erh tea fermentation method, which repeatedly turns over halfway, and the difficulty of temperature and humidity control; The varieties are complicated, and the quality of the finished product is uncontrollable; the dominant strains participatin...
