It was previously suggested that liquid membrane oscillator systems might be used for the manufacture of taste sensors. The influence of substances responsible for taste belonging to bitterness, sweetness, sourness and saltiness on oscillation patterns of a liquid membrane oscillator with cationic surfactant benzyldimethyltetradecylammonium chloride was examined. It was concluded that independently of the nature of the membrane solvent present in the liquid membrane phase, the oscillation characteristics are sensitive to the investigated taste substances in a specific way.
