An object of the present invention is to provide a stable crystalline α-D-glucosyl α-D-galactoside having low hygroscopicity and hardly losing fluidity, a saccharide containing the same, a production method thereof, and a use thereof. A crystalline α-D-glucosyl α-D-galactoside having a melting point of 119 ° C. to 123 ° C., a saccharide containing the crystalline α-D-glucosyl α-D-galactoside, and a crystalline α-D-glucosyl α-D-galactoside are prepared from a solution containing α-D-glucosyl α-D-galactoside. Crystallizing and collecting D-glucosyl α-D-galactoside, a method for producing crystalline α-D-glucosyl α-D-galactoside or a saccharide containing the same, and amorphous α-D -Method for converting glucosyl α-D-galactoside to crystalline α-D-glucosyl α-D-galactoside in the presence of water, and containing crystalline α-D-glucosyl α-D-galactoside and a saccharide containing the same The above problems are solved by establishing various compositions.
