Abstract

The invention discloses functional health-care tea and a preparation method thereof, and relates to the technical field of tea processing. The preparation method of the functional health-care tea of ​​the present invention comprises preparing purple bud tea extract and green tea powder through the steps of powder mixing, molding and drying, wherein the purple bud tea extract is prepared through the steps of pretreatment, rough extraction, purification and refining, etc. made. The invention extracts effective substances through micro-jet flow and electrodialysis, has high extraction efficiency, less damage to anthocyanins of purple bud tea, higher extraction purity, and the obtained finished product has good health care effect.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to functional health-care tea and a preparation method thereof. Background technique [0002] Purple bud tea is a tea named according to the color characteristics of the young buds and leaves of the tea green raw material. It is a finished or semi-finished product formed after processing tea greens from tea trees whose young buds and leaves are purple. Among the tea trees cultivated in my country, there are not many buds and leaves that are purple. In addition to the cultivation of ornamental tea trees, the conscious cultivation of purple bud-leaf tea trees is even rarer. National representative varieties mainly include "Zijuan" bred by the Tea Research Institute of Yunnan Academy of Agricultural Sciences, "Moss Fragrant Purple" bred in Zhejiang Province, "Dahongpao" and "Hongya Bergamot" bred in Fujian. [0003] The content of anthocyanins in purple bud tea is much higher ...
