According to the results of a questionnaire in the Program for International Student Assessment (PISA) conductedin 2006 by the Organization for Economic Co-operation and Development (OECD), high school students in Japan don't realize the interest and usefulness of learning science. Many events on science education targeting high schoolstudents have been held in an attempt to solve this problem. The purpose of this study is to develop a simple fabricatedtaste sensor with sensitivity and selectivity which can be applied in science class using filter paper and lipid solutions. The fabricated taste sensor with lipid membranes composed of trioctylmethylammonium chloride (TOMA) and phosphoric acid di(2-ethylhexyl) ester (PAEE) showed a good selectivity for sodium chloride (saltiness) and citric acid (sourness), respectively. In a sensory test, the results of sensors correspond to the sensory score. Thus, it was indicated that the fabricated taste sensor for education is a useful science teaching material.
