Abstract

An electronic tongue (e-tongue) consisted of a sensor array of the ion-selective electrode based on lipid/polymer membranes has been developed. The e-tongue consisted of 8 sensors with gold electrodes and equipped with an Arduino Mega 2560 Microcontroller-based data acquisition system. The lipid/polymer membranes were fabricated by combining polyvinyl chloride (PVC) as a matrix, 4 different kinds of plasticiser material (2-NPOE, bis(2-ethylhexyl) sebacate, bis(2-ethylhexyl) phosphate, and cis(1-butyl pentyl) adipate), and 4 different kinds of lipids (octadecyl amine, oleoyl alcohol, methyl trioctylammonium chloride, and oleic acid) for an active material. Potentiometric measurements were carried out with a reference electrode Ag/AgCl. Data logger was equipped with a moving average filter for reducing the noise. From the score plot of principal component analysis (PCA), the first and second PCs contribute 90.5% of the total variance. It indicates that the developed e-tongue is able to classify dairy products according to the types and brands.
