Edible oil analysis based on three dimensional fluorescence specscopy was introduced.The 3D fluorescence spectra of variety kinds edible oils was obtained by using Hitachi F7000,the peak value of thresholds of those experimental spectra was increased and analyzed.The results show that there are obvious characterizes between the variety kinds edible oils,so the fluorescence fingerprint technique can be used to distinguish various edible oils.There are also obvious differences between the edible oils with the fried edible oils at the central wavelength and the peak intensity of three dimensional fluorescence spectra.These fried edible oils were heated in high temperature for different minutes,whereas there is no significant distinction between their transmission spectrum.Therefore,the experiments prove that the three dimensional fluorescence spectroscopy is a practical quick analysis method for the edible oils both in kinds and in qualities.
