Steviol glycosides

Description

Steviol glycosides are natural compounds derived from the leaves of the Stevia rebaudiana plant. They are primarily responsible for the sweet taste of Stevia and are known for being 50 to 300 times sweeter than sucrose, while contributing zero or minimal calories. These compounds are used as non-nutritive sweeteners in a wide range of food and beverage products.

• Taste: Extremely sweet, with a clean taste that can sometimes have a slight bitter aftertaste

• Solubility: Moderately soluble in water

• Stability: Highly stable under heat and light, making them suitable for cooking and processing

• Sweetness Level: 50–300 times sweeter than sucrose depending on the specific glycoside (e.g., Stevioside, Rebaudioside A)

• Energy Value: Virtually zero calories

Applications

1. Food and Beverages:

   • Used in a wide variety of sugar-free and reduced-sugar products such as soft drinks, candies, desserts, and baked goods
