Stevia extract

Stevioside is extracted by immersing Stevia rebaudiana dry leaves in water, filtering the liquid from leaves and stems, and further using water or food grade alcohol for purification. Thus, a pure natural and extremely sweet sweetener stevioside, which does not affect the blood glucose level, is obtained.

The sweet components of stevioside are glycosides. Glucoside (or heteroside) is a compound composed of sugar or sugar derivative and another non sugar compound through the terminal carbon atom of sugar. Glycosides can be hydrolyzed into two parts, sugar and non sugar. The non sugar part is called aglycone or aglycone (Genin); Rebaudiside a, B, C, D, e. Dulcoside A and B, which belong to tetracyclic diterpenoid compounds, are glycosomes with the same diterpenoid ligands α- One glucose is connected to the carboxyl group, and then disaccharide or trisaccharide is connected to the C-13 position. Stevioside (STV) linked to C-13 and rebaudioside A (Reba) linked to C-13 have been identified as the main sweet components of stevioside; Rebaudioside A, D, C, E; Durcosteroside a. They are all glycosides with the same aglycone steviol. The difference between them lies in the type, quantity and form of the sugar bound on the glycoside bond. Stevia extract is calorie free and natural. However, the definition and identification requirements of "pure natural" may vary from country to country. At the same time, stevia extract is also safe, and its safety has been comprehensively reviewed and scientifically proved by many international organizations, including FAO / WHO Joint Expert Committee (JECFA) and European Food Safety Agency (EFSA). There was no side effect or allergy when Stevia extract was added to food and beverage.

Studies have shown that Stevia extract does not affect blood glucose levels or interfere with insulin. Stevia extract does not contain any calories, which can provide diabetics with more flexible choices in terms of total caloric intake and help to control their weight. No matter how much Stevia extract was taken, there was no effect on GI. Stevia rebaudiana extract can also be used in a variety of foods and beverages. The individual use and level of use may vary from country to country. When Stevia rebaudiana extract is combined with other sweeteners, there will be synergistic effect.
