Characteristic effects of taste-compounds on the dynamic behavior of oleate-monolayer.
Dynamic behavior of the monolayer of oleic acid on an aqueous solution was studied. The hysteresis loop of the surface, pressure (pi)-area (A) curve, was found to be characteristically dependent on the chemical stimuli with different taste-categories: salty, sweet, bitter and sour. The characteristic response of the dynamic surface behavior was discussed in relation with our recent finding, i.e., the features of the oscillation change in a different manner with the addition of various chemical species belonging to different taste categories in an excitable artificial liquid-membrane of oleic acid (Yoshikawa, et al, Langmuir, 4, 759-762 (1988).
