Evaluation of the tool needs to be done to determine the stability of the sensor made. The principle of the electronic tongue sensor used is potentiometry using a type of electrode with a liquid junction design. Solutions representing the five basic tastes were tested using 7 working electrodes coated with different lipid membranes and classified using Principal Component Analysis (PCA) methods. The results of the calculation of the silhouette score on the PCA is 0.93.enE-tongueLiquid junction working electrodeLipid membraneand PCAArticle
