Abstract

The invention provides a method for preparing fermented stevia rebaudiana tea. The method comprises the steps of selecting stevia rebaudiana plants growing well and harvesting the stevia rebaudiana plants; selecting fresh blades good in color and free of insect damage; placing the stevia rebaudiana blades in a temperature control chamber to perform withering until the leaves are soft; collecting the stevia rebaudiana blades and placing the stevia rebaudiana blades in a rolling machine to perform rolling, and performing rolling to a strip-shaped rolling state; placing the well rolled stevia rebaudiana blades in the temperature control chamber to perform fermentation, until the leaf red stain rate reaches 90% or above; drying the rolled stevia rebaudiana blades, and obtaining the fermented stevia rebaudiana tea. The method for preparing the fermented stevia rebaudiana tea is simple in process and convenient to operate; according to the fermented stevia rebaudiana tea obtained through the preparation method, not only can nutrient ingredients of stevia rebaudiana be released by brewing, but also the taste is good; and the fermented stevia rebaudiana tea has important application values. In addition, the fermented stevia rebaudiana tea has no additive ingredient, is all natural and safe to drink, and has good practical values.

Description

technical field [0001] The invention relates to the field of agricultural product processing, in particular to a method for preparing stevia fermented tea. Background technique [0002] Stevia is a perennial herbaceous plant of Compositae, native to subtropical South America. The roots, stems and leaves of Stevia rebaudiana contain steviol glycosides. Stevioside has the characteristics of high sweetness (200-300 times that of sucrose), low calorie (only 1 / 300 of sucrose), and can increase blood sugar, lower blood pressure, and promote metabolism. Heart disease, dental caries, etc. have a certain auxiliary effect, so it has increasingly attracted people's attention and attention, and has become the "third sugar source" after sucrose and synthetic sugar. [0003] The planting area of ​​stevia is also expanding, and the supply exceeds the demand. Stevia products are widely used in medicine and food additive industries. At present, stevia leaves are mainly used for stevia, a...
