Recent advances in electrochemical biosensors for antioxidant analysis in foodstuff

Antioxidants play an important role in human health and provide a defense against many diseases. Electrochemical biosensors are considered promising tools for antioxidant research due to their high sensitivity, fast response time, and ease of miniaturization and have penetrated a variety of markets, including food analysis, drug screening, and toxicity research. In this review, recent advances in current state-of-the-art electrochemical biosensors and antioxidant assessment strategies are discussed with a focus on the use of several biosensors, and their advantages and limitations for the rapid and precise analysis of antioxidants in foods. It is concluded that there is widespread applications of electrochaemical biosensors in food quality analysis, the functional evaluation of active factors, and effective components screening. The challenges associated with electrochemical biosensor technology and future directions in this field are also presented. (C) 2019 Published by Elsevier B.V.
