Embodiment 1

[0044] A kind of selenium-enriched dark tea, the preparation process of said selenium-enriched black tea is as follows:

[0045] Pick fresh tea leaves; pile the tea leaves into a pile of 8 cm high, and evenly kill the tea leaves with 110°C steam, turn the pile every 15 minutes, and repeat the operation 2-3 times; If the tea juice overflows and adheres to the surface, the tea leaves can also be dried naturally or not; sterilize the tea leaves with steam at 99°C for 3 minutes; Form a 75cm-high tea pile, ferment for 3 days, and control the fermentation temperature at 35°C; knead and roll the tea sticks after fermentation and flowering, and bake the tea sticks with pine charcoal until the water content is 7%, that is, selenium-enriched black tea.

[0046] According to GB / t21729-2008, the content of selenium in tea is detected. After the tea sample is heated and digested with acid, the hexavalent selenium in the sample is reduced to tetravalent selenium in 6mol / L hydrochloric acid ...

Embodiment 2

[0048] A kind of selenium-enriched dark tea, the preparation process of said selenium-enriched black tea is as follows:

[0049] Pick fresh tea leaves; pile the tea leaves into a pile of 10cm in height, use 110°C steam to kill the tea leaves evenly, turn the pile every 15 minutes, and repeat the operation 2-3 times; Knead into strips, and the tea juice overflows and attaches to the surface; steam sterilize the tea leaves at 120°C for 5 minutes; mix the sterilized tea leaves with the selenium-enriched fermentation bacteria cultivated by cultivation method 2, pile them into a pile of 80cm high tea, and ferment for 7 days , the fermentation temperature is controlled at 55°C; the fermented tea sticks after flowering are kneaded and rolled tightly, and the tea sticks are roasted with pine charcoal until the water content is 5%, that is, selenium-enriched black tea.

[0050] According to GB / t21729-2008, the content of selenium in tea is detected. After the tea sample is heated and dig...

Embodiment 3

[0052] A kind of selenium-enriched dark tea, the preparation process of said selenium-enriched black tea is as follows:

[0053] Pick fresh tea leaves; pile the tea leaves into a pile of 12cm high, uniformly kill the tea leaves with 110°C steam, turn the pile every 15 minutes, and repeat the operation 2-3 times; tea leaves, the tea juice overflowed and attached to the surface; steam sterilized the tea leaves at 110°C for 4 minutes; mixed the sterilized tea leaves with the selenium-enriched fermentation bacteria cultivated by cultivation method 3, and piled them into a pile of tea with a height of 85 cm, fermented for 5 days, and fermented The temperature is controlled at 40°C; the fermented tea sticks are re-kneaded and rolled tightly, and the tea sticks are roasted with pine charcoal until the water content is 5%, that is, selenium-enriched black tea.

[0054] According to GB / t21729-2008, the content of selenium in tea is detected. After the tea sample is heated and digested ...

Abstract

The present invention relates to selenium-enriched black tea and a processing method thereof. Second and third leaves under tender shoots are used as raw materials, and the selenium-enriched black tea is prepared by the steps of pickling, enzyme deactivating, rolling, sterilizing, fermenting, rolling again, charcoal baking, etc. The selenium-enriched black tea is obtained by using selenium-enriched eurotium cristatum fermented tea leaves, can supplement human body needed selenium element every day after drinking, and is low in production costs and more suitable for industrial production.

Description

technical field [0001] The invention relates to the field of tea processing, in particular to a selenium-enriched dark tea and a processing method thereof. Background technique [0002] Selenium is an essential trace element for the human body. Selenium participates in the synthesis of various selenium-containing enzymes and selenoproteins in the human body. Among them, glutathione peroxidase catalyzes the conversion of hydroperoxide or lipid peroxide into water or various alcohols in vivo, eliminates the attack of free radicals on biofilms, and protects biofilms from oxidative damage; Selenium can improve human immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. Selenium has obvious inhibitory and protective effects on colon cancer, skin cancer, liver cancer, breast cancer and other cancers, and its intermediate metabolite methyl enol in the body has strong anticancer activity. At the same time, selenium has the effect ...
