A pulse voltammetry electronic tongue can be a useful tool for determining the antioxidant capacity of fruit extract with minimum handling given the large number of electrodes it has. However, it is necessary to define the array of pulses to be applied to each electrode in order to obtain a pattern that characterize this property. In this study, from a generic array of 22 pulses (applying potentials between-800 and 900mV for 20ms each) and by employing statistical procedures (multivariate analysis), the best arrays of pulses has been defined to determine the antioxidant capacity of two Peruvian fruits (camu-camu and tumbo) for each electrode to constitute the pulse voltammetry electronic tongue (Au, Pt, Ir, Rh, Ag, Cu, Ni, and Co). Three arrays were obtained, one employing all 22 pulses applied to each electrode, which generated a large number of data, and two in which pulses and electrodes were reduced. Accordingly, the best one only used 3.4% of the initial voltammetry information, obtained from pulses at 900 and-850mV and applied to electrodes Ir and Au, and another at-600mV on an Ni electrode.
