Steviol glycosides are a family of naturally occurring diterpene glycosides found in the leaves of the stevia plant. The main components include stevioside, rebaudioside A, B, C, D, F, and M, each with distinct sweetness and taste profiles. Commercial stevia extracts are standardized to total steviol glycoside content, typically ≥80% or ≥95%. The sweetening potency and taste quality depend on the specific glycoside composition. Steviol glycosides are approved for use in food and beverages in over 60 countries. They are extracted using a water-based process and are considered natural sweeteners. They are thermally stable and maintain sweetness in acidic conditions.
