Abstract

The invention relates to a health-care tea making process, in particular to a process method for making health-care tea by fermenting sweet tea leaves. The making process comprises the following steps: taking sweet tea raw materials, pile fermentation, tea steaming, eurotium cristatum spore powder spraying, sterilizing after tea leaves are sealed, tea leaves fungus growing, ultrasonic processing, drying and packing and the like. The sweet tea making process has the ultrasonic treatment capacity, can reduce the autolysis phenomenon of eurotium cristatum, also can achieve the function of fixing golden flowers, is beneficial to protection of organic selenium to the greatest degree, reduces the high-temperature oxidative degradation of organic selenium, and meanwhile, and can also prevent the thalli of the golden flowers from being reduced under the high temperature condition, the quick fermentation is carried out by adopting a large amount of eurotium cristatum spore powder, the growth of infectious microbes is slowed down, the problem of mildewing of the sweet tea leaves is not caused, the influence of a culture medium in the eurotium cristatum solution on the original flavor of the tea leaves is avoided, the content of tea polyphenol is reduced through fermentation, and the stomach irritation influence is reduced, and the sweet tea is easily suitable for being drunk by people with diabetes by means of the sweet taste of rubusoside.

Description

technical field [0001] The invention belongs to the field of biological fermentation and relates to a manufacturing process of health-care tea, and more specifically relates to a process for making health-care tea by fermenting sweet tea leaves.
