Cyclodextrins are prepared by enzymatic treatment of starch. Commonly cyclodextrin glycosyltransferase (CGTase) is employed along with α-amylase. First starch is liquified either by heat treatment or using α-amylase, then CGTase is added for the enzymatic conversion. CGTases produce mixtures of cyclodextrins, thus the product of the conversion results in a mixture of the thr… WebThe cyclodextrins are cyclic oligosaccharides consisting of 7, 6, or 8 (respectively) glucopyranose units.
