Processing method of fructus cinnamomi black tea

Abstract

The invention relates to a fructus cinnamomi black tea processing method. The method comprises the following steps of 1) withering, spreading picked fresh fructus cinnamomi tea leaves in a withering tank, and controlling the environment temperature to be 20-35 DEG C, the air humidity to be 65-75% and the withering time to be 9-16 hours during withering; 2) rolling, putting the withered leaves treated in the step 1) into a rolling machine, and rolling until the cell damage rate of the withered leaves is more than 80% and the leaves are more than 90% into strips; (3) fermentation, uniformly spreading the rolled leaves treated in the step (2), then putting the rolled leaves into a fermentation box for fermentation, and stopping fermentation until the leaves have obvious flower and fruit fragrance or sweet fragrance and are orange red or purple bronze; 4) drying, drying the fermented tea leaves with gross fire until the water content of the tea leaves is 30-40%, and then drying with sufficient fire until the water content of the tea leaves is 6-7%; and 5) aroma enhancement, carrying out low-temperature baking aroma enhancement on the dried tea leaves. The method is advantaged in that the obtained fructus cinnamomi black tea is high in the aflavin content, obvious in flower fragrance, high in quality and suitable for batch popularization and production.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a method for processing Guiding black tea. Background technique [0002] Guiding tea is a unique rare tea tree variety in Hunan Province. It is produced in the depths of the mountains near Dolomite, a national 4A-level scenic spot, at an altitude of about 800 meters. It contains rich components, and the content of epigallocatechin gallate (EGCG) reaches about 10%. Due to its excellent quality, Guiding tea was once selected as a tribute tea by the imperial court, and was recorded in detail in "Hunan Tongzhi" and "Baoqing Fuzhi". [0003] Black tea is one of the six major teas in China. It is a fully fermented tea and has health effects such as anti-oxidation, softening blood vessels and nourishing the stomach. It is generally believed that tea tree varieties with large buds and leaves, rich components, high ester catechin content and moderate caffeine content are suitable...

AI Technical Summary

Problems solved by technology

The preparation process of ordinary black tea in the prior art mostly includes withering, rolling, fermentation, drying, etc., and is generally based on manual workshop production, wherein the production efficiency and product quality of manual tea are low, the output is small, and the labor cost is high. The production conditions of traditional production are poor, and the level of process control is low; therefore, after the traditional process is directly applied to the production of Guiding tea, the strain characteristics of Guiding tea with obvious floral fragrance and high theaflavin cannot be fully reflected
