Abstract

The invention mainly relates to a processing method of fungus growing for black tea. Raw dark green tea is processed through pile fermentation and steaming and is sprayed with eurotium cristatum spore powders; then tea leaves are pressed to form bricks, and are processed through high-temperature sterilization after being sealed up; after being cooled down, the tea leaves are processed through fungus growing for a period of time, and then are added with water for extraction under high temperature; liquid is concentrated and removed after liquid and residues are separated so as to form pastes; and the pastes are dried and packed. By adopting the processing method, the influence on the tea flavor that is caused after eurotium cristatum disappears can be avoided, the original tea flavor can also be kept, and the convenience for drinking eurotium cristatum milky tea can be facilitated when extracts are brewed directly.

Description

Technical field: [0001] The invention belongs to the field of natural product development, and relates to a production process of tea extract, more specifically to a production method of dark tea extract. 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 Newslett...
