Abstract

The invention provides a solid fermentation process of golden flower black tea. The solid fermentation process is characterized in that a method for inoculating eurotium cristatum on black tea in a fermentation process of a solid fermentation pot realizes non-pollution blooming of the black tea so as to prepare the golden flower black tea growing with flourish and uniform golden flower bacteria and a blooming flowering phase is controlled within 7 days. The golden flower black 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 108; the black tea leaves are yellow; 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 black 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 black tea.

Description

technical field [0001] The invention relates to a black tea, in particular to a solid fermentation process of Jinhua dark tea, and belongs to the technical field of dark tea processing. [0002] Background technique [0003] Chrysanthemum chrysogenum, the fungus coronoidis, is found in Fuzhuan tea. Fuzhuan brick tea is one of the most characteristic dark tea products among the six major tea categories. Its unique "Golden Flower" (Coronoids) belongs to post-fermented tea, Fully fermented tea. Modern scientific research, and authoritative experts through animal experiments, human clinical experiments, toxicology research, safety evaluation, and epidemiological investigations have shown that various extracts of Fuzhuan brick tea "Jinhua" have activation effects on PPARγ and PPARδ. There are two new active substances in "Golden Flower": Tea-Chrysin A and Tea-Chrysin B, which can significantly reduce fat compounds, blood lipids, blood pressure, blood sugar, and cholesterol in ...
