Abstract

The invention belongs to the technical field of tea processing, and more specifically relates to a dark tea rapid fermentation method. According to the dark tea rapid fermentation method, lactobacillus plantarum and lactobacillus acidophilus are combined to obtain a composite inocula for dark tea fermentation, and appropriate fermentation conditions are controlled, so that dark tea fermentation time is shortened, the whole fermentation period is shortened to 22 to 25 days, the fermentation period is about 15 days shorter than that of conventional pile fermentation technology. Tea obtained through the dark tea rapid fermentation method is high in tea polyphenol degradation amount, the contents of amino acids and theabrownin are increased, the tea fragrance is improved, and the taste is mellow and thick.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a rapid fermentation method for black tea. 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 method for tea alcoholization, the steps of which include: 1) vacuumize the fresh tea leaves to 0.08-0.09 MPa after packaging; 2) transfer the packaged tea leaves to a...
