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 at neutral pH (6.0–7.0) and moderate temperature (35–40 oC). The cylindraceous of alpha-cyclodextrin provides a hydrophobic cavity that allows formation of inclusion complexes with a variety of non-polar organic molecules of appropriate size. The hydrophilic nature of the outer surface of the cyclic structure makes alpha-cyclodextrin water-soluble.

Application:
Because the characteristics, Alpha-Cyclodextrin contain the water-fast subatance to transform to soluble substance keeping the volatile things diluting slowly and stably. Increasing the stability of the substance that easily to be deteroprated under the atmosphere and the light.so It is widely used in the drugs, food and flavor,nutritional ingredients and make them stable and diluting slowly. a-CD is also widely used in the field of pesticide and adjusting the metabolization of the crop and increasing the quantity of the crop. Especially the Cyclodextrin and its ramification which developed by these years,some of them are the important solutizer,stablizer, releaser or the assist materials of the Entericcoated drugs,some of them are the materials of organic synthetical macromolecular stuff. some are used in the father of the smeary water, some are used to systhesize and separate resin,some are used to the dye industry,some are used in the chemical sensitive materials,some are used in paper making industry,some are used in seperation of the organic chemical stuff, some are used in analytical chemistry and some are used in medical plastic industry.
