Electrochemical behaviour of polyphenol rich fruit juices using disposable screen-printed carbon electrodes: Towards a rapid sensor for antioxidant capacity and individual antioxidants

► SWV combined with disposable electrodes was used to measure the AC of berry-based juices. ► The sensor allowed for fast and easy discrimination of samples based on their AC. ► Black currants showed greater oxidation peaks at lower potentials indicating higher AC.
