Abstract

In order to develop a simple system for sensing taste substances, an optical method using polymer/lipid films doped with a voltage-sensitive dye and plastic optical fibers (POFs) has been studied experimentally. The several kinds of polymer/lipid blended membranes doped with rhodamine-B dye with a long hydrocarbon chain were used after transferring on to the glass substrate glued on the end surface of POF. Its fluorescence intensity around 600 nm showed different patterns for the taste substance solutions such as bitter, salty and "umami". These results and a principal component analysis gave the possibility of an optical fiber taste substance sensor.
