Example Embodiment

[0013] Example 1

[0014] Follow the steps below to prepare low-caffeine black tea:

[0015] (1) Fresh leaf picking: During the tea picking season, choose varieties suitable for making black tea (you can choose Jinguanyin, Huangdan, Hair Crab, Zhenghe Dabai Tea, Fuyun No. 6, Fuding Dahao Tea, Fuding Dabai Tea and other varieties ), pick the new shoots, one bud, two and three leaves of the tea tree, and spread them evenly on the tea withering device (such as water sieve, bamboo curtain or withering trough); it is not suitable to overlap, so as to prevent the overlapping part of the leaves from turning red and black; spread the leaves quickly , Brisk, open as soon as required, avoid repeating it to avoid mechanical damage and affect quality;

[0016] (2) Withering: using daylight withering or natural withering method to wither the fresh tea leaves evenly spread on the tea withering device to obtain the withered tea 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...
