Embodiment 1

[0021] Embodiment 1: a kind of black tea, the preparation method is as follows, step 1, pick fresh leaves, set aside. Step 2, withering, put the picked fresh leaves into the withering tank and spread them evenly, turn on the blower to wither, spread them to a thickness of 15cm, take 2 hours, turn them once in the middle, and get the withered leaves. Put the withered leaves into the green shaker and shake the blue and green greens, and carry out twice. The first shake green greens is based on light shaking. The rotating speed of the blue green shaker is 20r / min, and the time is 30min. Carry out shaking blue or green for the second time, the rotating speed of green or green shaker is 25r / min, and the time is 50min, after shaking green or green leaves, shake green leaves are put into withering tank, spread evenly, thickness is 15cm, until blade When the water content is 48%-50%, withered leaves are obtained.

[0022] Step 3, kneading, put the last withered leaves obtained in ste...

Abstract

The invention relates to the technical field of tea making and discloses black tea. The black tea is prepared by the following steps: taking fresh leaves, withering and rolling the fresh leaves and spraying fermentation treating fluid for fermentation, wherein solute of the fermentation treating fluid comprises polyoxyethylene xylitan monostearate, and the dosage of the polyoxyethylene xylitan monostearate in 1kg of fresh leaves is 5-25g; performing drum-roasting after fermentation, tidying tea strips with hands and drying the tea strips to obtain the black tea. The black tea has the advantages and benefits that the fresh leaves are fermented after being treated by the fermentation treating fluid before fermentation in the processing process of the black tea, so that a better restraining action on aroma-producing substances generated in the fermentation process can be achieved, and the decomposition of the aroma-producing substances can be inhibited; in addition, the prepared black teacan be used for decomposing fat, so that the black tea has an inhibition effect on nutritional adiposity, and the effects of decomposing the fat, losing weight and being good in storage stability canbe achieved.

Description

technical field [0001] The invention belongs to the technical field of tea making, in particular to black tea. technical background [0002] Black tea is a kind of tea with the largest tea output in the world. It is made from suitable fresh leaves of tea trees through withering, rolling, fermentation, drying and other processes. Among them, "fermentation" is the key process for the formation of black tea quality, which is a typical process. fermented tea. The aroma components of black tea are a series of formation and transformation in the process of fresh leaves from withering to final drying to form dry tea. The chemical components of the finished tea are significantly higher than those of fresh leaves, forming a good aroma. [0003] The aroma of black tea is generally formed in three aspects, namely, the inherent free aroma in fresh leaves, the aroma produced by enzymatic action of fresh leaves during processing, and the aroma formed by thermal physical and chemical chan...
