    摘要： A kojibiose phosphorylase which hydrolyzes kojibiose in the presence of an inorganic phosphoric acid to form D-glucose and &bgr;-D-glucose-1-phosphoric acid, forms kojibiose and an inorganic phosphoric acid from &bgr;-D-glucose-1-phosphoric acid, and catalyzes the transfer reaction of glucosyl group to other saccharides using &bgr;-D-glucose-1-phosphoric acid as a saccharide donor. The enzyme is obtainable from natural sources such as microorganisms of the genus Thermoanaerobium, and obtainable by recombinant technology. Kojibiose phosphorylase is used to transfer glucose from glucose-1-phosphate to acceptor saccharides to produce &agr;-D-glucosyl-1(1→5)-L-sorbose, kojibiosylglucose, kojibiosylglucoside and kojibiosylfructoside.

    摘要： .alpha.-Isomaltosyl .alpha.-isomaltoside represented by O-.alpha.-D-glucopyranosyl-(1.fwdarw.6)-.alpha.-D-glucopyranosyl O-.alpha.-D-glucopyranosyl-(1.fwdarw.6)-.alpha.-D-glucopyranoside is a novel non-reducing saccharide which promotes the growth of bifid bacteria, has an anti-caries activity, and promotes the mineral absorption. Similarly as the non-reducing saccharide, .alpha.-isomaltosyl .alpha.-glucoside and .alpha.-isomaltotriosyl .alpha.-glucoside can be also used to prevent caries and promote the growth of bifid bacteria and the mineral absorption. These saccharides can be used alone or in combination in a variety of foods, cosmetics and pharmaceuticals.
