DETECTION OF CORN AND SUNFLOWER OIL ADULTERATIONS OF OLIVE OILS USING FLUORESCENCE SPECTROSCOPY

A novel approach for the detection of admixtures of vegetable (corn and sunflower) oils in commercially available olive oils on a qualitative level is presented. Chemical analysis of the contents of fatty acids in each of the model systems under study is performed. The dependence of the ratio of the...

description A novel approach for the detection of admixtures of vegetable (corn and sunflower) oils in commercially available olive oils on a qualitative level is presented. Chemical analysis of the contents of fatty acids in each of the model systems under study is performed. The dependence of the ratio of the two main fluorescence intensity peaks 1 2 F / F and that of the linoleic to oleic acids C18:2 / C18:1 is studied. It is shown that an increase of the concentration of the adulterant the maximum of the first fluorescence peak exhibits a wavelength shift. Fluorescence analysis can be used for a qualitative real time determination of the presence ofadulterants in olive oil by comparison of the observed particular fluorescence spectrum with those from a database of spectra of olive oils and adulterants from a particular region.
