What Is Stevia?
Stevia serves as a natural sweetener derived from a plant, offering a calorie-free alternative to sugar. It's available in various forms, catering to different uses and preferences.
Botanical Origins of Stevia
Stevia rebaudiana is the botanical source of stevia, a perennial shrub native to South America. This plant, belonging to the Asteraceae family, has been used for centuries due to the natural sweetness of its leaves. Commonly referred to as sweet leaf or sugarleaf, Stevia rebaudiana's leaves are where the sweet compounds, integral to stevia-based sweeteners, are found.
Steviol Glycosides Explained
The sweetness of stevia comes from compounds known as steviol glycosides, primarily stevioside and rebaudioside. These molecules are up to 300 times sweeter than sucrose (table sugar), and they contribute zero calories when consumed, as the human body does not metabolize them for energy.
Forms of Stevia: Powder, Liquid, and Green Leaf
Stevia can be found in several forms:
Pure Stevia Extract: A fine white powder resulting from the purification of steviol glycosides.
Liquid Stevia: A solution made by steeping stevia leaves or mixing purified extracts with water, often with added glycerin or alcohol for stability.
Whole Leaf Stevia: The least processed form where the dried leaves are used directly. This form retains the natural green color and is less sweet compared to the extracts.
Each form offers a varying degree of sweetness and flavor profiles, making stevia a versatile addition to the market of natural sweeteners.
