Embodiment 1

[0022] A kind of white tea processing technology, its step comprises as follows:

[0023] (1) Picking fresh leaves: Picking fresh leaves of tea trees with "one bud and one leaf, one bud and two leaves";

[0024] (2) Pretreatment: Place the fresh leaves after acceptance in a constant temperature room, and spray 0.4% endoglucanase and 0.2% pectinase at a mass concentration of 0.4% at 50°C. The spraying speed is uniform, and the spraying flow rate is 200ml per minute; processing time is 0.5h:

[0025] (3) Airing green: Spread the pretreated fresh leaves evenly on soft plaques or bamboo mats with a thickness of 2cm. The relative humidity of the air in the spreading room is controlled at 90%, the room temperature is controlled at 15°C, and the leaf temperature is controlled at Within 30°C, for 2 hours, spread the fresh leaves until the leaves are soft, the tender stems are constantly folded, and a light fragrance is enough;

[0026] (4) Greening: Put the dried fresh leaves into t...

Embodiment 2

[0031] A kind of white tea processing technology, its step comprises as follows:

[0032] (1) Picking fresh leaves: Picking fresh leaves of tea trees with "one bud and one leaf, one bud and two leaves";

[0033] (2) Pretreatment: Place the fresh leaves after acceptance in a constant temperature room, and spray 0.3% endoglucanase and 0.3% pectinase at a mass concentration of 0.3% at 55°C. The spraying speed is uniform, and the spraying flow rate is Minute 120ml, processing time is 1h:

[0034] (3) Airing: spread the pretreated fresh leaves evenly on a soft plaque or bamboo mat with a thickness of 3 cm. The relative humidity of the air in the spreading room is controlled at 95%, the room temperature is controlled at 20°C, and the leaf temperature is controlled at Within 30°C, for 3 hours, spread the fresh leaves until the leaves are soft, the tender stems are constantly broken, and a light fragrance is enough;

[0035] (4) Greening: put the dried fresh leaves into the drum gre...

Embodiment 3

[0040] A kind of white tea processing technology, its step comprises as follows:

[0041] (1) Picking fresh leaves: Picking fresh leaves of tea trees with "one bud and one leaf, one bud and two leaves";

[0042] (2) Pretreatment: Place the fresh leaves after acceptance in a constant temperature room, and spray 0.35% endoglucanase and 0.25% pectinase at a mass concentration of 53°C. The spraying speed is uniform, and the spraying flow rate is Minute 150ml, processing time is 0.8h:

[0043] (3) Airing: spread the pretreated fresh leaves evenly on a soft plaque or bamboo mat with a thickness of 2 cm. The relative humidity of the air in the spreading room is controlled at 90%, the room temperature is controlled at 18°C, and the leaf temperature is controlled at Within 30°C, for 2.5 hours, spread the fresh leaves until the leaves are soft, the tender stems are constantly broken, and a light fragrance is enough;

Abstract

The invention discloses a white tea processing technology. The technology comprises the operations of pickling a raw material, preprocessing, deactivating enzymes, tidying tea strips, spreading, getting moisture, rebaking and the like, wherein the preprocessing operation is carried out through spraying fresh leaves with glucan endonuclease having a mass concentration of 0.3-0.4% and 0.2-0.3% pectase, has a certain effective promotion effect on the subsequent operations, shortens the whole production period by near 30%, improves the production efficiency, and deserves the large scale popularization.

Description

technical field [0001] The invention relates to a tea processing technology, in particular to a white tea processing technology. Background technique [0002] White tea is one of the six traditional Chinese teas. It is a specialty product in Anji, Zhejiang. There is no "pretreatment" procedure in the traditional tea-making process of white tea. Cooling, re-moisture, re-baking. [0003] The tea-making process lacks a "pretreatment" process, which leads to the reduction of the finished white tea extract, and the effective ingredients that can effectively improve the extraction of the finished white tea, and the entire process cycle is relatively long, and the production efficiency is low. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a processing technology for white tea. [0005] Technical solution: In order to achieve the above object, the invention provides a white tea ...
