The Composition of Stevia Extract
Stevia extract is derived from the leaves of the Stevia rebaudiana plant, which is renowned for its remarkable sweetness.The primary components responsible for this sweetness are known as steviol glycosides. These natural compounds are significantly sweeter than sucrose (table sugar), making them a popular choice for those seeking to reduce their sugar intake without sacrificing flavor.Steviol glycosides are a group of compounds that include several different types, with the most common being stevioside and rebaudioside A. Each of these glycosides has a unique sweetness profile and varying degrees of aftertaste. For instance, while stevioside is about 50-100 times sweeter than sugar, rebaudioside A can be up to 300 times sweeter.
This variance allows manufacturers to select specific glycosides based on desired taste and application.The sweetness of stevia extract comes from the interaction of these glycosides with taste receptors on the tongue. When consumed, steviol glycosides bind to sweet taste receptors, triggering a sweet sensation without contributing calories. This mechanism is particularly beneficial for individuals managing their weight or blood sugar levels, as stevia does not raise blood glucose levels.Upon ingestion, steviol glycosides undergo a metabolic process in the body. They are not absorbed in the upper gastrointestinal tract, which means they pass through largely intact until they reach the colon.
