CRYSTALLINE ?-D-GLUCOSYL ?-D-GALACTOSIDE, SACCHARIDE COMPOSITION COMPRISING THE SAME, PROCESS FOR PRODUCING THE SAME, AND USES THEREOF

摘要

A crystalline alpha -D-glucosyl alpha -D-galactoside which has a melting point of 119-123 DEG C; a saccharide composition comprising the same; a process for producing the same or the saccharide composition comprising the same, which comprises (i) crystallizing alpha -D-glucosyl alpha -D-galactoside from its solution and (ii) collecting the grown crystalline alpha -D-glucosyl alpha -D-galactoside; a method for converting amorphous alpha -D-glucosyl alpha -D-galactoside to crystalline alpha -D-glucosyl alpha -D-galactoside in the presence of moisture; and a composition comprising the crystalline alpha -D-glucosyl alpha -D-galactoside or the saccharide composition comprising the same.
