Anhydrous crystalline &bgr;-maltose, its preparation and uses

摘要

Objects of the present invention are to provide a novel anhydrous crystalline &bgr;-maltose, its preparation and uses. The present invention attains the above objects by providing an anhydrous crystalline &bgr;-maltose with a melting point of 154 to 159° C.; a process for producing the same, comprising a step of keeping hydrous crystalline &bgr;-maltose in an organic solvent at an ambient temperature or higher for the dehydration; and uses of the same.
