BioElectronic Tongue for the quantification of total polyphenol content in wine

► BioElectronic Tongue employing an array of enzyme-modified voltammetric biosensors. ► Use of Fast Fourier Transform for voltammetric data compression. ► Good accordance of total polyphenol content to reference methods for wine samples. ► Good discrimination of the different major phenolic compounds found in wine. ► Reagent-less alternative to classical methods such as Folin-Ciocalteu index or HPLC.
