Problems solved by technology

[0005] There is also a precedent for combining green tea, black tea, black tea and selenium and realizing the preparation of selenium-rich tea (green tea, black tea, black tea) in the related art; but there is no report for the preparation of selenium-rich white tea. In view of the special efficacy of white tea performance, it is a technical problem to be solved urgently to provide a kind of preparation method of selenium-enriched white tea

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 method for preparing selenium-enriched white tea and the selenium-enriched white tea prepared by the method. The method includes: controlling the growth temperature of the tea tree at 25-35°C 18-22 days before picking the tea leaves, and spraying an organic selenium solution on the tea buds once every ten days; fermented for 3-4 hours to obtain fermented tea leaves; the fermented tea leaves were dried to a water content of 6-10% at a relative humidity of 70-80% and a temperature of 24-28°C to obtain rich Selenium white tea. The selenium-enriched white tea prepared by the preparation method of the invention can remove excessive oxygen free radicals in the human body and prevent the destruction of cell membrane lipid peroxidation, and its anti-free radical effect is 300-500 times that of vitamin E and vitamin C.
