  • Detail
Feature:Alpha-cyclodextrin is a non-reducing cyclic saccharide comprised of six glucose units linked by alpha-1.4 bonds. It is produced by the action of cyclodextrin glucosyl transferase on hydrolysed starch syrups. The cavity of alpha-cyclodextrin is less than beta-cyclodextrin, so it is used to allow formation of inclusion complexes with little molecules. The solubility degree of Alpha-cyclodextrin in water is 14.5 g/100ml @ 25°C, so the situation that needs high solubility of cyclodextrin.

Application:

Alpha-cyclodextrin is widely used in the drugs, food, flavorand cosmetics. Alpha-cyclodextrin is also widely used in the field of pesticideand adjusting the metabolization of the crop and increasing the quantity of thecrop. Especially the cyclodextrin and its ramification which developed by theseyears,some of them are the important solutizer,stablizer, releaser or theassist materials of the Entericcoated drugs,some of them are the materials oforganic synthetical macromolecular stuff.
