In this paper, it was investigated an impact of taste inducing substances on the oscillation progress of electrochemical potential difference in a liquid membrane oscillator containing cationic surfactant. While analyzing the results obtained, there were applied histograms showing a correlation between the frequency and the number of peaks appearing on the oscillation curves. It was stated that the oscillation characteristics of systems with taste substances belonging to four basic taste classes (sweetness, sourness, saltiness, and bitterness) significantly differ from each other. The final conclusion is that the taste inducing substances have different impact on the oscillation characteristics depending on the taste class (one of four basic taste classes: sweetness, sourness, saltiness, and bitterness) they belong to.
