Steviol Glycosides Powder

Steviol glycosides represent a family of naturally occurring sweet compounds extracted from the leaves of Stevia rebaudiana Bertoni, a plant indigenous to South America. Unlike synthetic sweeteners, these compounds have been used for centuries by indigenous populations and are now recognized globally as a safe, zero-calorie sugar alternative.

The Chemistry Behind the Sweetness

At the molecular level, steviol glycosides are diterpene glycosides composed of a steviol aglycone backbone with various glucose molecules attached. The most abundant and commercially significant compounds include:

* Rebaudioside A (Reb A): The sweetest and most desirable compound, offering up to 350 times the sweetness of sucrose with minimal bitter aftertaste

* Rebaudioside D (Reb D): Emerging as the premium choice for its superior taste profile

* Rebaudioside M (Reb M): The newest generation offering sugar-like taste characteristics

* Stevioside: The most abundant compound in stevia leaves, though with a more pronounced aftertaste

Our extraction technology focuses on maximizing high-purity Rebaudioside A content (up to 98%+), ensuring optimal taste performance in your formulations.

We've established direct relationships with certified organic stevia farms across three continents, ensuring:

Geographic Diversity for Supply Security
