Now many plastic vessels are daily used for package of foods. They are very convenient but there is a problem of safety, which has lately become a subject of special interest. The purpose of the present study is to sensitively and easily measure the amount of polymer in solution using multichannel taste sensor. We used polyvinyl alcohol (PVA) as the polymer sample because it is soluble in water. As a result, we could detect 0.01% PVA solution. This is more sensitive than the detection limit using near infrared radiation (NIR) apparatus.
