The electronic tongue is based on electrochemical sensors combined with multivariate data analysis. The aim of this study was to evaluate the discriminating ability of the electronic tongue for the recognition of different milk and yoghurt samples from different producers and various dairy products from one producer. The results were evaluated by multivariate data analysis - Principal components analysis. The electronic tongue α-ASTREE (Alpha M.O.S) has successfully distinguished five brands of milk purchased on the Croatian market, five brands of yoghurt also purchased on Croatian market and differentiated among various products from one dairy producer.
