Problems solved by technology

[0003] Because the enzymatic reaction triggered by the addition of enzymes is very different from the series of biochemical reactions caused by the release of enzymes and other related substances by the microorganism itself, and the condition control of the enzyme action is not easy to control

Abstract

The invention discloses fast alcoholized dark green tea and a preparation method of the dark green tea. The preparation method comprises the following steps of: converting catechin with bitter taste in the raw dark green tea into theaflavin, thearubigin and theabrownin, degrading cellulose into glucose with sweet taste, converting insoluble pectin into soluble pectin (to increase the thickness of a tea soup), and degrading protein into amino acids with umami taste by adding microorganisms and an enzyme solution into the raw dark green tea under the condition with certain temperature and humidity, and applying chemical action to the resulting product in supplementation, and at last neutralizing partial acidic components with baking soda. The technical problems of long fermentation time and the generation of nauseating and sour smells in dark green tea pile fermentation are solved; the tea made from the dark green tea obtained by the preparation method disclosed by the invention is delicate and mellow in taste, orange red and transparent in tea soup, and rich in stale flavor; and the dark green tea is pretty high in contents such as soluble sugar, theaflavin, thearubigin and amino acid, and can reach the taste effect of old tea more than 5 years in about 4 days.

Description

technical field [0001] The invention relates to a tea and a processing method thereof, in particular to a dark tea prepared by rapid aging and a processing method thereof. Background technique [0002] Dark tea has a long history in our country, and its fermenting process is the key link to form the quality of black tea. However, the traditional process is relatively rough, and the fermenting time of fermenting is relatively long, usually more than one month. Vomiting, unstable tea contents. In recent years, with the increase of people's demand for dark tea products, rapid alcoholization has become a hot spot in the research of dark tea technology. However, due to the change of tea quality caused by various enzyme reactions and microbial changes in the heap fermentation, the mechanism is still under study. . CN102823693A describes a tea alcoholization method, the steps of which include: 1) vacuumize the fresh tea leaves to 0.08-0.09MPa after packaging; 2) transfer the pack...
