What is Rebaudioside A?
Rebaudioside A (CAS 58543-16-1), commercially known as Reb A, is a high-purity steviol glycoside extracted from the leaves of Stevia rebaudiana.
Where is Rebaudioside A used?
- Beverages: replaces sucrose and high-fructose corn syrup in carbonated drinks, flavored waters and ready-to-drink teas
- Dairy and bakery: yogurts, ice creams and reduced-sugar baked goods
- Pharmaceutical and nutraceutical: bitterness masking and palatability in oral dosage forms, syrups and dietary supplements
- Tabletop sweetener blends, often combined with erythritol or inulin
- It delivers intense sweetness estimated at 200 to 400 times that of sucrose.
Good to know: With zero caloric contribution, it is a primary ingredient of interest for sugar reduction programs across food, beverage, and pharmaceutical applications.
Commercial specifications
- White to off-white powder in varying purity grades, typically 60% to 99% content on a dry basis
- High-purity grades meeting USP and Ph. Eur. standards
- Bulk supply in 25 kg bags, with smaller packaging for R&D or pilot-scale procurement
