摘要: Abstract An authentication study of the Italian PDO (protected designation origin) extra virgin olive oil Chianti Classico was performed; UV–visible (UV–vis), Near-Infrared (NIR) and Mid-Infrared (MIR) spectroscopies were applied to a set samples representative whole production area. The non-selective signals (fingerprints) provided by three spectroscopic techniques utilised both individually jointly, after fusion respective profile vectors, in order build model for oil. Moreover, these results compared with those obtained gas chromatographic determination fatty acids composition. In characterise oils produced area, UNEQ (unequal class models) SIMCA (soft independent modelling analogy) employed on MIR, NIR UV–vis spectra, acid Finally, PLS (partial least square) regression UV–vis, MIR predict content oleic linoleic oils. UNEQ, performed selection relevant predictors, increase efficiency classification models. information from spectroscopy allowed reliable models checking authenticity .
