Difference Between Stevia & Rebaudiana-A?

What is the difference between Stevia (steviodise) & Rebaudioside A?


The best part of stevia leaf is Rebaudiana A. Stevia rebaudiana plant contains a high percentage of steviol glycoside (stevioside) and rebaudioside A, C, D & F. The Stevioside has a lingering aftertaste while Rebaudioside-A has no lingering or aftertaste. The Stevioside (Steviol Glycoside) traditionally makes up the majority of the sweetness. However, when the rebaudioside-A is higher than stevioside, the bitterness and aftertaste is eliminated or reduced. The filtration and purification process of stevia extract affect the quality, characteristics, concentration and taste. Rebaudioside A can be further filtered and purified up to 99%. That’s why Rebaudiana-A is more expensive. The more purified and concentrated the less bitter and more sweeter it is. It could actually goes up to 500 times sweeter than sugar.

When you see Stevia 90 or 95% Stevioside on the label, it doesn’t mean it’s a good quality or it has no bitterness and aftertaste.  Stevioside has an aftertaste even if it is 99% purified, but Rebaudioside A does not possess an aftertaste and has a sweetness flavor comparable to sugar.

The difference between Stevioside & Rebaudioside Scientifically explained:

Overview: The history, technical function and safety of rebaudioside A, a naturally occurring steviol glycoside, for use in food and beverages

Clinical studies provide further evidence that purified rebaudioside A has no effect on either blood pressure or glucose homeostasis. This paper summarizes the information used to conclude that high purity rebaudioside A (rebiana) produced to food-grade specifications and according to Good Manufacturing Practices is safe for human consumption under its intended conditions of use as a general purpose sweetener.
