Abstract
A cyclodextrin which when added to water produces a haze-free solution is made by the use of starch which contains at least about 90% amylopectin in a two-stage process wherein first a starch hydrolysate is formed by means of an alpha-amylase or an acid and a second subsequent step wherein the cyclodextrin is formed by means of a cyclodextrin-glycosyl-transferase.
