Sažetak
Near-infrared (NIR) spectroscopy (1100 – 2500 nm) was used to analyze the crude protein (CP) content of spelt (Triticum spelta L.). Modified partial least square (MPLS), principal component regression (PCR) and partial least square (PLS) techniques were used. Standard errors of calibration (SEC) were 5.57, 5.38 and 6.02 for MPLS, PLS and PCR, respectively, while standard errors of cross validation (SECV) were 6.19, 6.34 and 6.47 respectively. Comparing NIRS and the chemical procedure the standard error of prediction (SEP) for MPLS, PLS and PCR were 9.41, 8.87 and 9.50 respectively. It was concluded that NIR spectroscopy has a great potential for CP prediction in spelt and that the PLS method is superior to the PCR and MPLS methods.
