This paper reports the comparison of determination methods for extra virgin olive oil (EVOO) adulteration with two kinds of oils, refined olive oil (ROO) and soybean oil by 19 FNMR, 1 H NMR and chemical titration. The determination of adulteration of EVOO with ROO by 19 F NMR was comparable to the conventional method. The contents of oleic, linoleic and linolenic acids of different oil samples can be determined by both 1 H NMR and GC-MS. The results obtained from the two methods showed little differences. The adulteration of EVOO with soybean oil is detected by 1 H NMR, although the limit of detection of the adulteration level is not less than 4.5%. The research demonstrates that 19 F NMR can be a fast and convenient method to detect EVOO if it is adulterated with ROO and 1 H NMR can be a fast and convenient method to detect EVOO if it is adulterated with seed oils.
