To further determine whether the fitting Gaussian peak could beas a reference band and the ratios of different regions of probe band to reference band could be used to estimate the RC of the chickpea starch sample, the ASG/AGratio (the ratio of the area of the spectra in the fitting Gaussian peak to the area of the fitting Gaussian peak) and the AS/AGratio (the ratio of the spectral area to the area of the fitting Gaussian peak) were calculated and are shown in Table 1 and Table 2.
