Embodiment 1
[0023] Present embodiment relates to a kind of preparation method of stevia fermented tea, comprises the steps:
[0024] (1) Harvesting: select well-growing stevia plants for harvesting;
[0025] (2) Leaf selection: select fresh, good-colored, and pest-free leaves from the harvested stevia stalks;
[0026] (3) Withering: place the selected stevia leaves in a temperature-controlled room for withering, wherein the withering temperature is 20°C, and the ambient humidity is 22%, until the leaves are soft and the water content of the leaves is 68%;
[0027] (4) Kneading: Collect the withered stevia leaves, put them in a kneading machine and knead them until they are rolled into strips;
[0028] (5) Fermentation: Put the kneaded stevia leaves in a temperature-controlled room for fermentation, wherein the fermentation temperature is 30°C, and the ambient humidity is 80%, until the redness rate of the leaves reaches more than 90%;
Embodiment 2
[0031] Present embodiment relates to a kind of preparation method of stevia fermented tea, comprises the steps:
