Embodiment 1

[0014] Prepare decaffeinated black tea as follows:

[0015] (1) Picking fresh leaves: During the tea-picking season, choose varieties suitable for making black tea (you can choose Jinguanyin, Huangdan, Hairy Crab, Zhenghe Dabai, Fuyun No. 6, Fuding Dahaocha, Fuding Dabai, etc. ), picking new shoots, one bud, two or three leaves of tea trees, and spread them evenly and thinly on the tea withering device (such as water sieve, bamboo curtain or withering trough); it is not suitable to overlap, so as to avoid the color of overlapping leaves turning red and black; the action of spreading leaves should be quick , Light and fast, it is required to open immediately, and avoid repeating to avoid mechanical damage and affect the quality;

[0016] (2) Withering: Withering the fresh leaves of tea trees spread evenly and thinly on the tea withering device by sunlight withering or natural withering, to obtain withered leaves with a moderate water content of 58-64%.

Abstract

The invention relates to a processing technology of a black tea with low caffeine. The processing technology includes withering, rolling, fermenting, microwaving, boiling water extracting, dehydrating, slightly rolling and drying. Compared with processing technologies in prior art, the processing technology of the black tea with low caffeine has the advantages that the black tea is processed by combining microwaving and boiling water extracting, microwaves can crush and ferment prolhallial cells, so that deprivation of caffeine in hot water can be facilitated, caffeine content in the prepared black tea with low caffeine decreases to below 0.5% and meet international optimality criterion, and tea quality is identical to or close to that of ordinary black tea. A production device is simple and effective, the prepared black tea with low caffeine is beneficial to some neurastheniac, pregnant women, children and crowds with weak heart and liver functions.

Description

technical field [0001] The invention relates to a processing technology of low-caffeine black tea. Background technique [0002] Black tea is a kind of fully fermented tea, which is refined from the buds and leaves of tea trees through typical processes such as withering, rolling (cutting), fermentation, and drying. Black tea has various health care functions such as anti-aging, anti-tumor, anti-fatigue, lowering cholesterol, and preventing arteriosclerosis to the human body. It is one of the most popular beverages for consumers. However, because black tea contains caffeine that excites the brain and the heart, some people with neurasthenia, pregnant women, children, and people with weak heart and liver function may experience physical discomfort or other side effects after drinking tea with high caffeine content for a long time. Low-caffeine tea can not only meet the needs of these consumer groups for drinking tea, but also can segment the tea market and improve the refine...
