Lactoneotrehalose, fremstilling deraf og anvendelse deraf

摘要

Lactoneotrehalose, a novel saccharide shown by the formula O- beta -D-galactopyranosyl-(1->4)-O- beta -D-glucopyranosyl alpha -D-glucopyranoside, is prepared by allowing a saccharide-transferring enzyme to act on an aqueous solution containing lactose and amylaceous substance. Lactoneotrehalose is a non-reducing oligosaccharide, extremely stable, readily soluble in water, and substantially free of hygroscopicity, as well as having a satisfiable quality and moderate sweetness. These render lactoneotrehalose very useful in the preparations of orally-administrable products, cosmetics and pharmaceuticals.
