Problems solved by technology

[0003] However, at present, waxberry teas are all wildly collected from different sources, and the prepared waxberry teas are of poor quality, usually rough in processing, less green in color, heavy in smoke, and inherent in waxberry after brewing. Bitter and astringent taste, on the other hand, due to the unscientific preparation process, the active ingredients are lost too much in the production process, which reduces the health function of tea

Abstract

The invention discloses chimonanthus nitens-containing tea and a preparation method thereof. According to the preparation method, adopted tea leaves are composed of chimonanthus nitens leaves and teatree leaves at a weight ratio of 1:4-5. The preparation method comprises the steps of picking, pretreatment, primary enzyme deactivation, secondary enzyme deactivation, rolling and drying. The chimonanthus nitens leaves and the tea tree leaves are reasonably proportioned by weight; according to the present invention, the tea leaves are prepared by using the scientific and reasonable preparation process, the sensory evaluation effect of the obtained tea is good, more antioxidant substances can be retained, especially the classified enzyme deactivating manner is used, and an enzymatic hydrolysate is sprayed during the secondary enzyme deactivation, such that the sensory score of the tea and the content of total polyphenols and flavonoids can be substantially improved, and the quality of thetea is substantially improved.

Description

technical field [0001] The invention belongs to the technical field of tea manufacturing and processing, and in particular relates to tea leaves containing wax plum and a preparation method thereof.
