A taste sensor utilizes lipid/polymer membranes for measuring taste. The sensor was improved to measure ethanol concentration. First, experiments were made about the responses to ethanol using a negatively charged lipid/polymer membrane and the positively charged lipid/polymer membrane. As a result, we found that a TDAB membrane has a higher response to ethanol than a 2C10 membrane. Next, the ethanol concentration of sake was measured using the characteristic of the above-mentioned membrane. Consequently, there was about 2% of measurement errors. Finally, measurement errors were nearly zero when pretreated with ion-exchange resin to the sample.
