Abstract

The invention relates to high-quality dark green tea and a processing technique thereof. The processing technique comprises the steps of pile fermentation, tea steaming, fermentation inducer adding, tea leaves pressing, tea leaf fermentation, drying and the like; in the step of pile fermentation, raw dark green tea is added with fresh tea leaf homogenate with high enzyme activity to effectively promote transformation of tea leaf matrix and flavor substance during pile fermentation and provide beneficial growth matrix for eurotium cristatum and other beneficial microorganisms in the fermentation process; the high-efficiency fermentation inducer composed of eurotium cristatum and hansenula debaryomyces hansenii is added to improve the purity of the microbial population, improve the microbial population structure and enable the fermentation period to be shortened to be 3-5 days, the high-quality dark green tea has dense golden flowers and rich arohid flavor, the quality of fu brick tea is remarkably improved and the processing cost is reduced; the environment temperature and the environment humidity in the fermentation process are controlled optimally, the beneficial microorganism population growth is promoted and the quality and the flavor of finished tea are effectively improved.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a high-quality dark tea and a processing technology thereof. Background technique [0002] Dark tea is one of the six major types of tea in my country, and it is also a major type of tea unique to my country. Dark tea is favored by consumers because of its lipid-lowering weight loss, blood sugar-lowering, and liver-protecting effects. Fuzhuan, as a very distinctive type of black tea, has been a necessities of life for people in the northwest frontier for many years and has a long drinking history. The special feature of Fu brick tea lies in the unique "flowering" process in the processing process: under the conditions of controlled temperature and humidity, a large number of golden-yellow microbial communities are produced, commonly known as "golden flowers". "Golden Flower", scientific name Eurotium cristatum is an important indicator to determine the quality of Fu brick tea. ...
