Beta cyclodextrin is widely used in the separation of organic compounds and for organic synthesis, as well as medical excipients and food additives. The inclusion of natural cyclodextrin and modified cyclodextrin and some drug molecules that are not biocompatible are now prepared. It not only increases the biocompatibility of the drug, but also plays the role of sustained release.JDK Has operated Vitamins and Amino Acid in the market for nearly 20years, it has a complete supplying chain from order, production,storage, dispatch, shipment and after-sale services. Different grades of products can be customized. We are always focusing on top-quality products, to meet the markets’ requirement and offer best service.
