Identification of the Principle of Taste Sensors to Detect Non-Charged Bitter Substances by 1H-NMR Measurement

Misaki Ishida, Haruna Ide, Keishiro Arima, Zeyu Zhao, Toshiro Matsui, Kiyoshi Toko
2022 Sensors  
However, due to the characteristic of detecting taste by changes in membrane potential, taste sensors cannot measure non-charged bitter substances.  ...  Therefore, we have been developing taste sensors to detect bitter tastes caused by non-charged substances such as caffeine.  ...  Conflicts of Interest: The authors declare no conflict of interest.  ...
