Reactant 2

HCID 6255beta-Maltose

HCID 7427Trehalose

Product 1

HCID 493591Maltitol

Procedure

The maltitol-rich fraction obtained in the above was treated in accordance with the above method for treating the trehalose-rich fraction to obtain a crystalline powder with a maltitol purity of about 93%, except that the maltitol-rich fraction was previously concentrated to give a concentration of about 80%. The yield of solid contents in the step was about 85%, d.s.b. Since the product shows substantially no reducibility, a sharpened sweetness, and a relatively-low-dental-caries-inducibility, it can be arbitrarily used in food products, cosmetics, and pharmaceuticals.
