Technical Abstract: Two-dimensional vibrational spectroscopy was employed to reveal spectral effects associated with changes in protein and carbohydrate composition in rice flower. Near-infrared and Raman spectroscopies were utilized in conjunction with this method to overcome hidden effects due to overlapping bands that are unobservable with the use of one-dimensional spectra. The results indicated considerable correlation with water in the NIR spectra whereas this did not occur with Raman spectra. This suggests that Raman spectroscopy may be more suitable for the analysis of flours when moisture content is variable.
