Deep eutectic solvents (DES) as green extraction media for antioxidants electrochemical quantification in extra-virgin olive oils
A new electroanalytical method has been developed for the determination of polar antioxidant compounds in
extra virgin olive oils. This method is based on the extraction of polar antioxidant compounds from extra-virgin
olive oils by means of a deep eutectic solvent and their determination by a modified screen-printed electrode
platform. The platform sensitivity was increased by modifying the working electrode with MWCNT and TiO2
nanoparticles as modifiers and Nafion as a binder. The platform showed very good sensitivity in detecting polar
