What is the difference between Stevia, Rebaudiana-A & Rebaudiana-M?
Stevia is the name of the plant. Stevia rebaudiana plant contains a high percentage of steviol glycoside (stevioside & rebaudioside A, C, D, F & M). Rebaudioside-A and Rebaudioside-M are the best ingredient of all steviol glycosides.
Rebaudioside-M (Rebaudiana-M, Reb-M):
Rebaudioside-M is considered the Next Generation of stevia sweetener. Researchers have discovered a novel minor steviol glycoside in stevia leaves, called rebaudioside M.
What is the advantage of Reb-M 95%?
-
Reb-M 95% has more sweetness potency and less aftertaste. It has a superior flavour profile compared to other steviol glycosides. The taste is round and soft, sweet from the tip of the tongue, without aftertaste, very similar to sugar. It is 400 times sweeter than sugar.
-
Owing to its sugar-like taste, it allows for greater amounts of sugar to be replaced with Reb-M 95%, while maintaining the clear soft sweetness without the lingering aftertaste.
-
Reb-M has a water solubility of 0.1 g/100 mL at 25 °C.
-
With its pure sugar-like taste Reb-M is being used instead of sugar in beverages, ice cream, tabletop sweetener, desserts, dairy products, confectionery, baking, canned fruits, pickled foods, and other products.
Why is Rebaudiana-M 95% more costly?
Rebaudioside-A accounts for 5% of stevia leaves, while Rebaudioside-M is present in less than 0.1%. This limited availability requires a more intricate purification process to achieve a high concentration of Reb-M, resulting in its higher price compared to Reb-A. To make it more cost-effective, Reb-M can be blended with other stevia sweeteners.
Nonetheless, Rebaudioside-A 98% continues to be the preferred choice for many due to its exceptional taste, affordability, and strong popularity.

Rebaudioside-A (Rebaudiana-A, Reb-A):
Reb-A is still the best option in terms of cost and quality. Stevia leaves contain 5% Rebaudioside A and can be further filtered and purified up to 99%. That’s why Rebaudioside-A is more expensive than Stevioside. The more purified and concentrated the less bitter and more sweeter it tasts. It could actually goes up to 400 times sweeter than sugar.
