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.
