PROBLEM TO BE SOLVED: To accurately and efficiently grasp the intensity of aftertaste.;SOLUTION: A first film potential Va of a molecular film, which is formed from a mixture of a polymeric material, lipid and a plasticizer and has a prescribed thickness, obtained when the molecular film is immersed in a standard liquid and the second film potential Vb of the molecular film obtained, when the molecular film is immersed in a sample liquid are calculated; and thereafter, the molecular film is preliminarily cleaned with a cleaning liquid and the preliminary cleaned molecular film is immersed in the standard liquid to calculate third film potential Vc and the molecular film is further cleaned completely with the cleaning liquid. A series of these treatments are performed, with respect to a plurality of sample liquids different in aftertaste, the difference between the first and second film potentials obtained with respect to one sample liquid is set to a first response value Vs, and the difference between the first and third film potentials is set to a second response value Vr and data relating the ratio R of two response values, with the intensity of the actual aftertaste of each sample liquid being calculated. Similar treatment is applied to a liquid to be measured, to calculate the ratio, and the intensity of the aftertaste of the liquid to be measured is calculated, on the basis of the ratio and the data.;COPYRIGHT: (C)2002,JPO
