Abstract
Different from conventional heterogeneous multiple-branched cyclodextrins having branches derived from the same kind of saccharide molecule, the inventive heterogeneous multiple-branched cyclodextrin has branches derived from different kinds of saccharides of, one, glucose and, the other, a maltooligosaccharide. The inventive heterogeneous multiple-branched cyclodextrins are more stable than conventional ones and useful as an ingredient of medical, foodstuff and cosmetic preparations. The heterogeneous multiple-branched cyclodextrin can be prepared from a mixture of a maltooligosaccharide and a glucosyl cyclodextrin by the reverse action of debranching enzyme.
