The invention discloses an olive oil flavor detection method based on an electronic nose and a gas phase-ion mobility spectrometry. The method comprises the following steps: (1) quantitatively selecting different brands of olive oil in the market and filling the olive oil in a gas phase bottle; (2) measuring different flavor response values by using an electronic nose by adopting a headspace sampling method; (3) measuring volatile substances (VOCs) by using a gas phase-ion mobility spectrometry; and (4) evaluating and analyzing the olive oil on the basis of a VOCs fingerprint spectrum by combining analysis results of the olive oil and the VOCs fingerprint spectrum.
