Stevioside, is a glycoside extracted from the leaves of Compositae, which is called stevia in China. The macroporous adsorbent resin has stronger selectivity for the adsorption of stevia and has obvious advantages. Therefore, the extraction process of stevioside entered a rapid development track along the resin adsorption technology. Resin adsorption is a common method of stevioside production. It is fast, economical, stable and durable. The professional stevioside extraction and purification resin produced by Suzhou Bojie has the advantages of ideal polarity, pore structure and specific surface area, fast adsorption speed, easy analysis and regeneration, etc., and is widely used in the market.
