Abstract

The invention mainly relates to a processing method for fungus growing of the black tea. The method comprises the following steps: the black tea raw material is pile-fermented, steamed, and sprayed with spore powder of eurotium cristatum; the tea leaves are formed by pressing, and sealed and disinfected at high temperature; and the tea leaves are cooled, and after a period of time of fungus growing, the tea leaves are fixed and dried. The method has the advantages that the fermentation time can be shortened; thalluses inside and outside the brick tea can grow uniformly and luxuriantly; the color of the golden flower can retain for a long time; and the golden flower can also stay all the time.

Description

Technical field: [0001] The invention belongs to the field of biological fermentation, and relates to a dark tea blooming process, and more specifically relates to a more comprehensive black tea blooming process. Background technique [0002] Jinhua is the common name of Eurotium Crisstatum, which grows in traditional Fuzhuan tea. The fungus has the characteristics of promoting the transformation of various organic substances in tea, greatly improving the quality and nutrition of fermented tea, making the tea soup brownish red, pure in aroma and mellow in taste. Modern research also shows that it has the functions of improving human blood biochemical indicators and obviously removing greasy, digesting, reducing fat and losing weight. Therefore, it has attracted more and more attention. In order to promote the flowering of various teas, many tea researchers have conducted a lot of research, for example: "Research on Flowering Technology of Fuzhuan Tea" was recorded in "Tea ...
