Zusammenfassung:The invention discloses a method for identify kiwi fruits from different producing areas by means of combination of an electronic tongue and a partial least squares analysis method. The method includes: collecting kiwi fruit samples from Hunan, Shaanxi and Sichuan; peeling the kiwi fruit samples and then carrying out freeze drying; respectively adding water into the kiwi fruit samples subjected tofreeze drying for manufacturing a plurality of samples in different regions; sealing and placing the samples under the condition of 20 DEG C to 25 DEG C, so that solution generated by the sample is collected by using the electronic tongue; determining electronic tongue sensor response values of methane, ethanol, alkane, oxynitride, aromatic components and organic sulfide in the solution, and respectively marking the parameters as Y(Hunan), Y(Shaanxi) and Y(Sichuan). According to a discrimination model, an electronic tongue system is utilized to extract and detect fruit compounds, sources of fruit production places ar
