Recent Advances in Electrochemical Rapid Detection Techniques for Bisphenol A in Food

Bisphenol A (BPA) is an organic compound widely used in the production of polycarbonate plastics and epoxy resins, commonly found in food containers and packaging. Due to its potential endocrine-disrupting properties, BPA can enter the human body through the food chain and has been linked to various health issues, including obesity, behavioral disorders, and reproductive system diseases. Therefore, developing simple, sensitive, and reliable methods for detecting BPA is crucial for ensuring food safety and protecting human health. Rapid detection techniques have gained significant attention for their simplicity, efficiency, flexibility, and cost-effectiveness. In particular, electrochemical methods have emerged as a promising approach for BPA detection, owing to their simple operation, high sensitivity, and potential for real-time monitoring. This review summarizes recent advances in electrochemical rapid detection technologies for BPA in food. It begins with an overview of regulatory limits for BPA in food and contact materials, as well as the fundamental principles of electrochemical detection. Subsequently, it provides an in-depth discussion of the application and progress of commonly used nanomaterial-modified electrochemical detection techniques in BPA analysis, highlighting their performance advantages. Finally, the challenges and future development directions of electrochemical BPA detection technologies are explored.
