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.
As a leading provider of separation and purification materials and solutions in China, Sunresin has successfully industrialized the Seplite® resins as well as the Sepsolut® SMB system for steviol glycoside purification in various EPC projects since 2009. While improving product quality, Sunresin’s technology also improves production efficiency and reduces cost, thus promoting the technological upgrading in the whole stevia industry.
