Fluorescence spectroscopy followed by multivariate treatment of the spectral data was used to establish the composition of binary mixtures of extra virgin olive oil (EVOO) with other low-cost edible oils. The partial least-squares regression (PLS) was utilized to develop calibration models between the synchronous fluorescence spectra (AX = 10, 30, 60 nm) and the composition of mixtures of EVOO with sunflower oil or EVOO with refined olive oil. All of the tested models pointed out significant correlations between spectra and mixture composition. The calibration models showed similar performance using all of the examined synchronous florescence spectra. (original abstract)

Spektroskopia fluorescencyjna wraz z chemometryczną analizą danych wykorzystana została do określenia składu mieszanin oliwy extra virgin z olejami gorszej jakości. Analizę regresji cząstkowych najmniejszych kwadratów (PLS) zastosowano do opracowania modeli kalibracyjnych dla widm synchronicznych fluorescencji (AX = 10, 30, 60 nm) mieszanin oliwy z oliwek i oleju słonecznikowego oraz oliwy z oliwek i oliwy rafinowanej. Dla wszystkich otrzymanych modeli uzyskano dobrą korelację widm i składu mieszanin. Modele kalibracyjne charakteryzowały się podobnymi parametrami dla wszystkich analizowanych widm synchronicznych.
