The invention relates to a method for detecting the freshness of a mango by using an acoustic surface wave (ASW) detector. The method comprises the following steps of: (1) standing a weighed mango to be detected between two energy converters of the ASW detector in a transverse manner and a longitudinal manner respectively, enabling the distance from one end, nearest to the mango to be detected, of the two energy converters to the mango to be detected to be 1-5 mm, and starting up the ASW detector and carrying out detection for 30-60 s; and (2) gathe |
