A kind of preparation technology of selenium-enriched black tea

Abstract

The invention relates to a black tea fungus growing process, and in particular relates to a technology for making selenium-rich black tea. The technology comprises the following steps: carrying out pile fermentation on raw black tea material, steaming the tea, spraying eurotium cristatum conidial powder onto the tea, sealing the tea and then sterilizing, carrying out fungus growing process on the tea, carrying out ultrasonic treatment, etc. By adopting the ultrasonic treatment, the method can reduce the autolysis phenomenon of eurotium cristatum, and also has the function of fixing golden flowers, thus being beneficial to protecting organic selenium to the utmost extent, reducing the high-temperature oxidative degradation of the organic selenium, and preventing the thallus from being reduced by the golden flowers under the high-temperature condition. A great deal of eurotium cristatum conidial powder is adopted for quick fermentation, so that the growth of sundry fungus can be reduced, the problem of tea mildew can be avoided, and the influence of a culture medium in the eurotium cristatum liquid to the original flavor of the tea can be avoided.

Description

Technical field:

[0001] The invention belongs to the field of biological fermentation, and relates to a black tea blooming process, and more specifically relates to a production process of selenium-enriched black tea. Background technique

[0002] Selenium is known by scientists as the "king of anti-cancer" among trace elements in the human body. Research in the scientific community has found that the level of blood selenium is closely related to the occurrence of cancer. A large number of survey data show that the level of selenium content in food and soil in an area is directly related to the incidence of cancer. For example, if the content of selenium in food and soil in this area is high, the incidence and mortality of cancer are low, and vice versa. , the incidence and mortality of cancer in this area are high, and the facts show that selenium is closely related to the occurrence of cancer. At the same time, the scientific community also recognizes that selenium is the...
