Detection of adulterants in grape nectars by attenuated total reflectance Fourier-transform mid-infrared spectroscopy and multivariate classification strategies

•The detection of grape nectar adulteration with cashew or apple was studied.•One-class and multiclass approaches were implemented.•The multivariate classification methods SIMCA, PLS-DA and PLS-DM were compared.•PLS-DA provided better performance to detect grape nectar adulterations. There is no any...
