ABSTRACT:
Novel crystalline maltotetraosyl glucoside is obtained by crystallizing maltotetraosyl glucoside from a solution of maltotetraosyl glucoside, prepared by either exposing an aqueous solution of maltopentaose to the action of a non-reducing saccharide-forming enzyme or an aqueous solution which contains trehalose or a non-reducing saccharide to the action of cyclomaltodextrin glucanotransferase. The crystalline maltotetraosyl glucoside has non-hygroscopicity, non-reducibility, superior solubility, less fermentability, and other satisfactory properties of stabilizing oligopeptides and biologically-substances as well as preventing retrogradation of amylaceous substances. These features render the crystalline maltotetraosyl glucoside very useful in various compositions including foods, beverages, cosmetics, pharmaceuticals and shaped bodies.
