| Summary: | Although the electronic tongue (e-tongue) was first introduced more than 20 years ago, the few commercial versions available today are rather expensive. This paper demonstrates an easy approach to the implementation of a laboratory e-tongue capable of discriminating the taste of a number of food and beverage products, by integrating readily available commercial parts. This e-tongue was implemented on a PC by interfacing an array of chalcogenide-based potentiometric sensors with a Silver/Silver Chloride reference electrode, data acquisition module and controlled/analyzed by the ubiquitous MATLAB software. Two graphical user interfaces (GUI) developed in MATLAB environment are presented to demonstrate easy control of the e-tongue and its analysis. The data acquired from experiments were subjected to statistical analysis and the performance of this instrument is presented in Principal Component Analysis (PCA) plots. These results show that the relatively simple e-tongue can effectively discriminate the tastes of the various agro-products.
