Benefits of technology

This patented technology allows for improved green teas that have better flavor quality without losing their original nutritional value during storage or shipping. By adding this method after washing with water at temperatures between 20°C-35°C, it can prevent bacterial growth on the tea's surfaces while still maintain its desired properties such as smell and sweetness. Additionally, these methods involve two steps - firstly reducing the pH level from acidic levels (pH 3.5-5) towards neutrality followed secondly increasing the temperature gradually over several hours until reaching 42-63 degrees Celsius. These techniques help preserve the natural ingredients found within them even when they lose some of their effectiveness caused by heat treatment.

Problems solved by technology

The technical problem addressed in this patented research relates to developing highly flavorful dark green or yellow tea that enhances its taste while reducing excessive volatile compounds during manufacturing process.

Embodiment 1

[0022] Embodiment 1: the preparation of Guizhou high fragrance black tea

[0023] (1) Tea picking: Pick tea before 10:00 on sunny days, pick one bud and one leaf, one bud and two leaves, one bud and three leaves, and use bamboo frames to place fresh leaves to keep ventilation;

[0024] (2) Soak green: put the fresh tea leaves into 2% saline solution for soaking, the temperature of the solution is 30°C, soak and wash;

[0025] (4) Spreading: Put the tea leaves that have been soaked green into clean water for soaking and washing, spread them to a thickness of 2-4cm, and wait for the water to filter and dry;

[0026] (5) Kneading process: the tea leaves obtained in step (4) are kneaded at cold temperature, the temperature is controlled at 2° C., and the kneading time is 40 minutes, so that the tea sticks are viscous, and the cell fragmentation rate reaches more than 95%;

[0027] (6) Fermentation process: the fermentation of tea leaves is divided into three steps: the first step is

Abstract

The invention provides a preparation method of Guizhou high-fragrance black tea. The preparation method comprises the following steps: picking tea leaves; soaking tea leaves; spreading the tea leaves;twisting the tea leaves; fermenting the tea leaves; shaping the tea leaves; drying the tea leaves. According to the preparation method of Guizhou high-fragrance black tea, based on the prior art, a soaking and washing step is added, and twisting is carried out under a low-temperature condition, so that deactivation of active enzyme due to high-temperature fermentation can be avoided, and the fermentation activity is higher; in addition, according to the fermentation properties of the tea leaves, three-step fermentation is adopted, and the prepared tea leaves have the advantages that the colorof made tea is ruddy, the tea is more red and dense in color and is more bright-colored, the fragrant smell is heavier and mellower and is more lasting, the taste is mellower, more smooth, and more dense, and the bottom parts of the tea leaves are more red and brighter.
