What is Rebaudioside-A?

Rebaudioside A, also known as Reb-A, is a steviol glycoside which, along with steviosides, is found in the leaves of the Stevia rebaudiana plant, the so-called sweet herb.

What makes the Stevia plant so sweet?

Together with stevioside, rebaudioside A forms the main component of the sweet ingredients of the Stevia leaf. Depending on the growing region and plant variety, 7-10 steviol glycosides may be present. Other steviol glycosides are found in the leaves of the Stevia plant, but in much lower quantities. These are in detail: Rebaudioside C, Rebaudioside D, Rebaudioside E, Rebaudioside F, Rebaudioside M, Dulcoside A and Rubusoside.

The positive sensory properties of rebaudioside A are particularly noteworthy. Unlike stevioside, rebaudioside-A has no bitter aftertaste. It has the purest and sweetest taste of all steviol glycosides. Stevia products with a purity of Rebaudioside-A 98% currently represent the highest possible concentration of Rebaudioside A and are of high quality.

As the sweetening power of rebaudioside-A exceeds that of sugar many times over, the sweetener should be dosed extremely sparingly. In its native Paraguay, the Stevia plant is also called honey herb or sweet herb because of its sweetening power.
