Abstract

The invention provides a solid fermentation process of golden flower Puer tea. The solid fermentation process is characterized in that a method for inoculating eurotium cristatum on Puer tea in a fermentation process of a solid fermentation pot realizes non-pollution blooming of the Puer tea so as to prepare the golden flower Puer tea growing with flourish and uniform golden flower bacteria and a blooming flowering phase is controlled within 7 days. The golden flower Puer tea prepared by the solid fermentation process disclosed by the invention is more in golden flower bacteria quantity; the golden flower bacteria quantity in each gram of dry tea leaves is more than 107. The liquid color is golden yellow, the aroma is pure and the taste is pure and mild; the effect of scraping oil, reducing fat and losing weight is further realized; the solid fermentation pot is firstly used for manufacturing the Puer tea and a blooming step is simplified; a flowering phase is shortened and the possibility of polluting the black tea by infectious microbes is avoided; the potential safety problem of the black tea is made up; the solid fermentation process is good for people to further approve and accept the Puer tea.

Description

technical field [0001] The invention relates to Pu'er tea, in particular to a solid fermentation process of Jinhua Pu'er tea, and belongs to the technical field of Pu'er tea processing. Background technique [0002] It belongs to dark tea, and it got its name because its place of origin used to belong to Pu'er Prefecture, Yunnan Province (now Pu'er City). Now it generally refers to the tea produced in the Pu'er tea area, which is loose tea and pressed tea made from the large-leaf sun-dried green tea in Yunnan, which is recognized as the Pu'er tea area, and processed through post-fermentation. The appearance is brownish red, the inner substance is red and bright, the aroma is unique and fragrant, the taste is mellow and sweet, and the bottom of the leaf is brownish red. There are raw tea and cooked tea, and raw tea is naturally fermented. Ripe tea is made of Yunnan large-leaf sun-dried green tea that meets the environmental conditions of the Pu'er tea production area. The ...
