Catalytic Mechanisms and Influence Factors on Cyclodextrin Preparation

Abstract:

Cyclodextrins(CDs) are mainly prepared from starch by the catalyzation of cyclodextrin glucosyltransferase(CGTase).In addition to the source of CGTase,many factors influence the ratio and specificity of CDs,such as reaction time,reaction temperature,pH,enzyme quantity,additive,type of substrate,substrate concentration,pretreatment of raw material et al.The CDs preparation processes are also effected by these factors.However,no system reports focused on the influence factors for CDs preparation.In this paper,we described the catalytic mechanisms of CDs preparation,and a review on the influence factors in CDs preparation process was presented,in order to provide reference for CDs preparation.
