Process for preparing compositions containing neotrehalose

Neotrehalose is prepared in a relatively high-yield by a process comprising allowing β-galactosidase to act on a solution containing lactoneotrehalose to form neotrehalose and recoverying the resultant neotrehalose. The neotrehalose is a non-reducing oligosaccharide having a satisfiable stability and a rich- and high-quality-sweetness and is assimilated and utilized as energy source in vivo when orally administered. Neotrehalose in the form of crystal has a satisfiable handleability because it is readily soluble in water and substantially free of hygroscopicity. These render neotrehalose very useful in the fields of food-, cosmetic- and pharmaceutical-industries.

Synthesis and glycosylation shift of 1,1'-disaccharides

Nineteen kinds of nonreducing 1,1'-disaccharides have synthesized by modified Koenigs-Knorr method, and characterized by NMR. The glycosylation shift of each anomeric carbon has been estimated.
