The elaboration of a sensitive taste sensor for discrimination of different soft drinks
is very important in food industry. The short review of taste sensors described in the literature
is presented. Two types of potentiometric taste sensors, one with lipophilic compound-polymer
membranes (ISE) and the other with lipid polymer membrane and a conducting polymer film
(All solid state electrode, ASSE) were tested in appropriate taste solutions. Five channel ISE
sensor was examined in acid, sour and sweet solutions. This sensor was sensitive to bitter
and sour substances and not too sensitive to sucrose concentration. It was successfully used for
discrimination of different kind of soft drinks. Four channel ASSE sensor was examined in
sour solutions. It was found that stability and sensitivity of ASSE are lower than ISE.
Therefore, it seems that the previous one cannot be applied in taste sensor.
