We studied infrared spectral characteristics derived from disaccharides and the interaction between disaccharides and water. Six kinds of sugar-H2O solutions (trehalose, kojibiose, nigerose, maltose, isomaltose and sucrose) and three kinds of sugar-D2O solutions (trehalose, maltose and sucrose) were prepared. Their infrared spectra were collected by use of a FT-IR/ATR method. The different spectral pattern in the fingerprint region was found for each sugar in H2O solution. Especially, characteristic spectral features were observed for trehalose. We compared the absorption bands of the trehalose, maltose and sucrose spectra in H2O with those in D2O based on the absorption intensity and wavenumber. As the results, the solvent affected the absorption intensity rather than wavenumber shift, which was caused by the interaction between disaccharides and solvents. In addition, when plotted against the disaccharide concentration, the absorbance of glycosidic linkage and C-OH vibration bands in H2O and D2O, showed good linearity in trehalose, while non-linearity in sucrose. Their bands of trehalose shifted slightly both in the H2O and D2O and the shifts of sucrose were significant. Judging from the spectral patterns, trehalose seems to be stable in both H2O and D2O.
