要約(英語): Recently, development of taste sensor is furthered for quality control of foods. In this study, we developed taste sensor with stearic acid LB films for measurement of high-intensity sweetener taste. We measured several high-intensity sweeteners with the number of layers of stearic acid LB films as 10 and 20 layers. And we also measured mixed high-intensity sweeteners. The result showed that the stearic acid LB films taste sensor was used to detect glucose and high-intensity sweeteners at a threshold level of taste. Stearic acid LB films sensor detects different response by mixed ratio of high-intensity sweeteners. In addition, we compared difference of sensor responses by three kind of storing conditions (vacuum vessel, KCl solution and the air storing). The result showed that the structure of stearic acid LB films is easily affected by moisture in storage environment. This study indicated that the modification of stearic acid LB film layers and materials makes it possible to develop high sensitivity and selectivity taste sensor for sweeteners.
