Abstract
Disclosed is the use of amylopectin potato starch obtained from potatoes whose amylose formation is inhibited through breeding, or through genetic engineering or other molecular biological processes, as starting material for a process for production of cyclodextrin from potato starch by reaction with cyclodextrin glycosyltransferase. This starch starting material combines the positive effects of natural amylopectin starch with those of potato starch and is distinguished, among other properties, through low lipid and protein content and therefore higher purity. The yield of cyclodextrins is surprisingly high. In this way cyclodextrin can be produced at much lower cost than previously and can therefore be used for the first time on a larger scale in technical processes.
