Embodiment 1

[0025] Please refer to figure 1 , the preparation method of this selenium-enriched white tea provided by the invention comprises the following steps:

[0026] Step 101: Control the growth temperature of the tea tree at 25-35°C 18-22 days before picking the tea leaves, and spray the organic selenium solution on the tea buds once every ten days;

[0027] Step 101 is the stage of applying selenium to the tea leaves before picking. In this process, in order to enable the leaves of the tea buds to effectively absorb the organic selenium solution, it has been found through practice that the absorption effect is greater when there is sufficient sunlight and the temperature is between 25-35°C. will be better. Therefore, 20 days before tea picking, it is controlled between 25-35°C, and sprayed every ten days until tea picking is carried out.

[0028] In addition, spring tea and autumn tea are preferred in the tea picking process, and when spraying organic selenium solution, it is pre...

Embodiment 2

[0038] In the present embodiment, the preparation method of the preparation method of selenium-enriched white tea comprises the following steps:

[0039] S1: Control the growth temperature of the tea tree at 25-35°C 18-22 days before picking the tea leaves, and spray the organic selenium solution on the tea buds once every ten days.

[0040] Wherein, in the organic selenium solution, the mass ratio of water to liquid organic selenium is 750 to 800:1; for example, 100 milliliters of liquid organic selenium is prepared per 75 kilograms of water (specifically: 1 microgram of selenous acid Sodium is dissolved in 1-2 liters of aqueous solution) and used to spray an acre of tea forest. After spraying, the selenium in the sodium selenite solution is absorbed through the surface of the tea leaves. And, in a further technical solution, the variety of the tea tree is Fuding Dabaicha or Fuding Dahaocha, and the above two kinds of tea trees are of good quality, which is beneficial to the...

Abstract

The invention relates to the field of tea preparation, in particular to a preparation method of selenium-rich white tea and the selenium-rich white tea prepared with the method. The method comprises steps as follows: the growth temperature of a tea tree is controlled in the range of 25-35 DEG C about 18-22 days earlier than tea picking, and an organic selenium solution is sprayed on tea buds for each ten days; the tea is fermented for 3-4 hours under the condition of relative humidity of 70%-80%, and fermented tea is obtained; and the fermented tea is dried under the condition of relative humidity of 70%-80% at the temperature of 24 DEG C-28 DEG C until the water content is 6%-10%, and the selenium-rich white tea is obtained. The selenium-rich white tea prepared with the preparation method can clear excessive oxygen radical in a human body, lipid peroxidation damage of a cell membrane is prevented, and the anti-free radical action of the selenium-rich white tea is 300-500 times of vitamin E and vitamin C.

Description

technical field [0001] The invention relates to the field of tea preparation, in particular to a method for preparing selenium-enriched white tea and the selenium-enriched white tea prepared by the method.
