What Is Stevia?
What is Stevia?
Stevia is a new natural sweetener extracted from the stevia leaves (Stevia Rebaudiana Bertoni). The active compounds of stevia are steviol glycosides (mainly stevioside and rebaudioside), which have up to 200-300 times the sweetness of sugar. Stevia compounds are heat-stable, pH-stable, but some of its extracts may have a bitter aftertaste at high concentrations.
Stevia has a high sugar sweetness with low calorie. Its sweetness is 200-300 times that of sugar and its caloric value is 1/300 that of sugar. After a large amount of laboratory tests, stevia sugar has been proven to be without any toxic and side-effect, non-carcinogenic and is safe to be consumed. If taken frequently, it can benefits a lot of diseases such as high blood pressure, diabetes, obesity, heart disease and tooth decay, etc. It is an ideal sugar alternative sweetener. Stevia can be widely used in food, beverages and drinks, medicine, chemical products for daily use, wine-making, cosmetics, flavorings and etc. It is recognized as “The 3rd International Sweetener Source”.
What is Steviol glycosides?
Steviol glycosides are high intensity sweeteners, 30-300 times sweeter than sucrose. They are isolated and purified from the leaves of the stevia plant (Stevia rebaudiana Bertoni).
Steviol glycosides are glycosides of steviol. their molecules can be viewed as a steviol molecule, with its carboxylhydrogen atom replaced by a glucose molecule to form an ester, and a hydroxyl hydrogen with combinations of glucose and rhamnose to form an acetal.
Steviol glycosides powder is a high intensive sweetener with low calorie, which is 200-450 times sweeter than that of sugar. Its calorie is only 1/300 than cane sugar. Steviol glycosides can be widely used in food, beverage, medicine, wine and other industries.
Stevia extracts mainly contain 9 Steviol glycosides: Stevioside, Rebaudioside A, Rebaudioside B, Rebaudioside C, Rebaudioside D, Rebaudioside F, Dulcoside A, Rubusoside and Steviolbioside.
What is Steviol?
Steviol is a diterpene, it is the base structure of steviol glycoside. Steviol occurs in the plant as steviol glycosides.
