The invention provides an efficient enzymatic method for the preparation of branched cyclodextrins such as glucosyl and maltosyl cyclodextrins. The inventive method comprises the enzymatic reaction of a branch-splitting enzyme and .beta.-amylase simultaneously with a mixture of a cyclodextrin and starch. Alternatively, a branched cyclodextrin is obtained from a mixture of a cyclodextrin and maltose in an enzymatic reaction with pullulanase, optionally, with admixture of an alcohol such as ethyl and propyl alcohols or a glycol such as ethyleneglycol and propyleneglycol to the reaction mixture. A glucosyl cyclodextrin can be obtained by the steps of first subjecting a mixture of a cyclodextrin and maltose to an enzymatic reaction with pullulanase and then subjecting the reaction product to a second enzymatic reaction in the presence of an enzyme mixture composed of takaamylase and glucoamylase and yeast.
