Abstract: The immobilized cyclodextrin glycosyltransferase(CGTase) was used for preparation of cyclodextrin(CD).The influence of reaction time,concentration of alcohol and liquification degree of starch on yield of CD was discussed.The highest yield of CD could reach 54% and the main product was β-CD.The activity of immobilized CGTase lost very little after repeated use.

Key words: immobilization, cyclodextrin glycosyltransferase, cyclodextrin
