Abstract: In order to expand the application of Fourier transform infrared (FTIR) spectroscopy to analyze edible oils, we herein summarize recent advances in the application of FTIR spectroscopy for evaluating the quality and safety of edible oils. Oil quality has been evaluated in terms of physicochemical properties (peroxide value, trans fatty acid content, free fatty acid content, moisture content, iodine value, carbonyl value and multivariable analysis) and oxidative stability. The safety of edible oils has been tested by assessing their authenticity. This review is focused on the discussion of spectral acquisition, waveband selection, data processing and substrate effect elimination.

Key words: Fourier transform infrared (FTIR) spectroscopy, edible oils, quality analysis, safety testing
