Recent trends in the electroanalytical detection of food fraud

摘要

Food fraud is a criminal act that has continuously increased in the recent years and represents an important issue to consumers’ confidence, which encompass economic, social, health and religious aspects. Electrochemical sensors are a promising category of analytical techniques for food authenticity assessment due to their low cost, simplicity/easiness-to-perform, sensitivity and sensibility in comparison to other consolidated assays. Herein, a background on the transduction mechanisms of potentiometric, amperometric and impedimetric sensors is provided in addition to some current applications on the authentication of food products.
