Problems solved by technology

[0003] Stevia rebaudiana seeds are small, loose skin tissue, less nutrients stored in seeds, easily permeable to water and air, and lose vitality due to increased respiration, resulting in short life of seeds. Therefore, a method that can delay the shelf life of stevia rebaudiana seeds is needed

Abstract

The invention provides a stevia rebaudiana seed preservation method which comprises the following steps: (1) collecting stevia rebaudiana seeds, and naturally sun-curing to make the water content be 3-5%; and (2) wrapping the stevia rebaudiana seeds with gauze, placing the gauze wrapping the stevia rebaudiana seeds and a moisture-proof agent in a glass vessel, sealing, placing the glass vessel in a ventilation environment with the environment temperature of 8-12 DEG C, and preserving. The stevia rebaudiana seed preservation method can effectively prevent moisture and air from entering the seeds, slows down the respiration of the seeds, thereby delaying the inactivation time of the seeds and prolonging the preservation life of the seeds.

Description

technical field [0001] The invention relates to the field of stevia seed preservation, in particular to a stevia seed preservation method. Background technique [0002] Stevia is a perennial herb of the genus Stevia in the Asteraceae family. The whole Stevia plant contains sugar, and the sweetness of the leaves is the highest, containing about 14% glycosides. The glycosides of the branches are equivalent to half of the leaves. Stevia leaves can be used as sugar after drying and crushing, or through ethanol precipitation Obtain stevioside, the sweetness is equivalent to 250-300 times that of white sugar, and the calories are only 1 / 300 of white sugar. Not only that, stevioside has no toxic side effects, no carcinogens, safe to eat, regular consumption can prevent high blood pressure , diabetes, obesity, heart disease, dental caries and other diseases, it is an ideal sweetener to replace sucrose. At present, it has been widely used in food, beverage, medicine, daily chemical...
