Abstract
Abstract New α-glycosyl glycyrrhizins bearing two or more α-glucose residues are prepared. Such α-glycosylation is carried out by subjecting an aqueous solution of glycyrrhizin (or a salt thereof) and an amylaceous substance (e.g. starch or cyclodextrin) to the enzymatic action of an α-glycosyl transferase (e.g. cyclodextrin glucanotrasferase). The α-glycosyl glycyrrhizins are low-caloric, low-cariogenic, mild, non-bitter, non-lingering sweeteners which may be advantageously incorporated into foods, beverages, cosmetics, dentifrices and drugs.
