Sunresin’s Stevia Extraction and Purification Technology

Steviol glycoside is a natural sweetener extracted from stevia leaves of the Compositae herbaceous plant. Thanks to its advantages such as high sweetness (200-450 times sweeter than sucrose), low calorie, natural source and desirable taste, it is recognized as an ideal substitute for sucrose, also known as "the third source of sugar in the world", and is widely used in food, beverage, medicine industries.
