Problems solved by technology

However, in the existing black tea processing process, due to improper processing technology, the processed black tea has a low dissolution rate of active ingredients after soaking. The content of tea water extracts in traditional black tea is about 30%, and tea polyphenols account for about 30% of dry black tea leaves. less than 20% of the weight, and then the value of the prepared black tea is low, reducing the quality of the prepared black tea

Embodiment 1

[0024] A preparation method of black tea, comprising the following steps:

[0025] S1. Picking: picking fresh leaves of tea trees with one bud and one leaf and the length of the bud and leaf is 2.6cm, and set aside;

[0026] S2. Withering: Withering the picked fresh leaves of the tea tree, the temperature of the withering room is controlled at 28° C., and the withering time is 8 hours, ready for use;

[0027] S3. Kneading: Spray the solution on the tea leaves after the withering treatment. The consumption of the solution is 25% of the weight of the tea leaves. Gently knead for 10 minutes and set aside for use. The solution is prepared from hijiki extract, sorbitol solution and sodium bicarbonate solution in a weight ratio of 10:8:2;

[0028] S4. Fermentation: Before fermentation, all the kneaded leaves that form agglomerates after kneading are disbanded, and the kneaded leaves are disbanded and placed in a fermentation tank for fermentation. The fermentation process is divide...

Embodiment 2

[0035] A preparation method of black tea, comprising the following steps:

[0036] S1. Picking: picking fresh leaves of tea trees with one bud and two leaves and a bud-leaf length of 2.7 cm, and set aside;

[0037] S2. Withering: Withering the picked fresh leaves of the tea tree, the temperature of the withering room is controlled at 32°C, and the withering time is 16 hours, and it is set aside;

[0038] S3. Kneading: Spray the solution on the tea leaves after withering, the amount of the solution is 35% of the weight of the tea leaves, and then the tea leaves are sent into the kneading machine for kneading. When kneading, knead lightly for 20 minutes, then knead again for 18 minutes, and then knead the tea leaves. Gently knead for 20 minutes and set aside for use. The solution is prepared from hijiki extract, sorbitol solution and sodium bicarbonate solution in a weight ratio of 20:16:3;

[0039] S4. Fermentation: Before fermentation, all the kneaded leaves that have been kn...

Embodiment 3

[0046] A preparation method of black tea, comprising the following steps:

[0047] S1. Picking: picking fresh leaves of tea trees with one bud and one leaf and the length of the bud and leaf is 2.6cm, and set aside;

[0048] S2. Withering: wither the fresh leaves of the tea tree picked, the temperature of the withering chamber is controlled at 30°C, and the withering time is 12 hours, and it is set aside;

[0049] S3. Kneading: Spray the solution on the tea leaves after withering, the amount of the solution is 30% of the weight of the tea leaves, and then the tea leaves are sent into the kneading machine for kneading. When kneading, knead lightly for 17 minutes, then knead again for 15 minutes, then Gently knead for 15 minutes and set aside for use. The solution is prepared from hijiki extract, sorbitol solution and sodium bicarbonate solution in a weight ratio of 15:12:2;

Abstract

The invention discloses a preparation method of black tea, and belongs to the technical field of tea processing. The preparation method comprises the following steps of picking tea tree fresh leaves,withering the picked tea tree fresh leaves, spraying solutions onto the withered tea leaves, then conveying the treated tea leaves into a rolling machine for rolling, putting the rolled leaves in a fermentation box for fermentation, and baking the tea leaves after fermentation treatment so as to obtain finished products of the black tea. According to the preparation method disclosed by the invention, when the tea leaves are rolled, the specially-made solutions are added, so that the occurrence of physical and chemical transition of the tea leaves is effectively promoted, moisture generates diffusion and permeation, water is stuffed between cells, and the green and astringent taste is volatilized; and besides, the cell permeability of the tea leaves can be improved, the increase of the permeability of cell membranes facilitates substance exchange between cells and peripheral environment, effective components in the cells are focused in vacuoles, the passage in which the effective components flow out of the cells is unimpeded, and the dissolution rate of the effective components of the black tea is greatly increased. The tea soup of the black tea prepared by the preparation method disclosed by the invention is red and bright, rich in fragrance and mellow and sweet in taste.

Description

technical field [0001] The present invention relates to tea, in particular to a method for the preparation of black tea. Background technique [0002] Tea is a drink made from the leaves or buds of the Camellia sinensis plant that originated in China. As a well-known health drink, tealeaves is the contribution of the people in southern China to the Chinese food culture in ancient times. There are many ingredients contained in tea leaves, nearly 500 kinds. Caffeine, theophylline, theobromine, choline, xanthine, flavonoids and glycosides, tea tannins, catechins, terpenes, phenols, alcohols, aldehydes, acids, esters, Aromatic oil compounds, carbohydrates, multivitamins, proteins and amino acids. Amino acids include cysteine, methionine, glutamic acid, and arginine. Tea also contains calcium, phosphorus, iron, fluorine, iodine, manganese, molybdenum, zinc, selenium, copper, germanium, magnesium and other minerals. Therefore, tea can eliminate food and get tired, reduce fire...
