Abstract

Some hydrophobic (including both the non-polar and polar) and hydrophilic polymer adsorbents were designed and synthesized, and their adsorption properties and adsorption mechanism toward stevia glycosides were studied in great detail. The skeleton structure and polarity of the resins had effect on the adsorption capacity and the selectivity properties during the adsorption of stevioside and rebaudioside A. A sweetener with high rebaudioside A content was isolated by using the adsorption selectivity of the polar resins.
