In general, beer degradation is evaluated by sensory test, however it depends on the subjectivity of an inspector. Therefore, it is highly required that an objective evaluation method is developed. It has been clarified that the degradation degree of beer proceeds mainly by oxidation of components derived from malt and formation of non-electrolyte trans-2-nonenal. In this study, we developed LB film taste sensor using metal complex for evaluating the degradation degree of beer with trans-2-nonenal concentrations. In addition, the physical properties of three metal electrodes and sensing film surface were evaluated with AFM and FT-IR, and these results and the sensor response characteristics were compared and discussed for improving the sensitivity as a sensor for beer degradation evaluation.
