Abstract: Near-infrared transmission (NIRT) spectroscopy was used in an attempt to predict moisture content, protein content and amylose content from undried whole-grain rough rice spectra. One hundred-fifty undried rough rice samples were collected. Using partial least squares calibration models obtained from undried whole-grain rough rice spectra, the coefficient of determination (r 2) and the standard error of prediction (SEP) of the validation set were r 2 = 0.96 and SEP = 0.70 for rough rice moisture content, r 2 = 0.70 and SEP = 0.24 for brown rice protein content, r 2 = 0.76 and SEP = 0.22 for milled rice protein content, and r 2 = 0.00 and SEP = 0.27 for milled rice amylose content. The results of the validation indicated that NIRT could be used to determine moisture content and protein content. Thus, NIRT technology may be used to classify undried rough rice into qualitative groups such as high protein content rice and low protein content rice upon arrival at a rice-drying facility after harvesting.
