POWDERED MILK BY NIR SPECTROSCOPY.Leastsquares support vector machines (LS-SVM) were used as an alternative multivariate calibration method for the simultaneous quantification of some common adulterants found in powdered milk samples, using near-infrared spectroscopy.Excellent models were built using LS-SVM for determining R 2 , RMSECV and RMSEP values.LS-SVMs show superior performance for quantifying starch, whey and sucrose in powdered milk samples in relation to PLSR.This study shows that it is possible to determine precisely the amount of one and two common adulterants simultaneously in powdered milk samples using LS-SVM and NIR spectra.
