Description

Steviol 19-Glucoside is a key steviol glycoside, a natural high-intensity sweetener compound derived from the leaves of the *Stevia rebaudiana* plant. This compound matters for its role as a precursor and intermediate in the production and purification of other major sweet-tasting glycosides like Rebaudioside A and Stevioside. Manufacturers in the food, beverage, and nutraceutical industries require it for research, development, and the formulation of next-generation, calorie-free sweetening solutions.

Application

• Food & Beverage Ingredient: Used as a high-purity intermediate in the manufacturing of commercial stevia-based sweeteners.
• Nutraceutical & Dietary Supplement Formulation: Serves as a critical component in developing sugar-free health supplements and functional foods.
• Pharmaceutical Research: Employed in studies investigating the metabolic pathways and potential therapeutic benefits of steviol glycosides.
• Flavor & Taste Modulation: Utilized in R&D to study and improve the taste profile of stevia extracts, reducing bitterness and enhancing sweetness.
• Analytical Reference Standard: Acts as a certified reference material (CRM) for quality control and HPLC analysis in laboratories.
• Biochemical Synthesis: Functions as a substrate or intermediate in enzymatic or chemical processes to produce other steviol derivatives.
