Bisphenols (BPs) are worldwide used organic compounds in plastics, belonging to the group of endocrine disrupting chemicals (EDCs) which exhibits endocrine disruption to beings. Migration of BPs from food contact materials like plastic containers, epoxy coatings in metal cans and thermal papers, would results in bioaccumulation of BPs in human beings, causing adverse health effects. Therefore, sensitive and selective determination of BPs in food is needed. Among different strategies have been explored for the detection of BPs, electrochemical sensors with relatively high sensitivity and fast response are promising. This paper is devoted to comprehensively review the developed electrochemical methods for BPs sensing in food, so that to find a direction for developing low cost, high accuracy and compatibility sensors toward the sensitive and selective detection of BPs. Different electrochemical technologies categorized by recognition agents, aptamers, enzymes, molecularly imprinted polymers and nanomaterials are discussed and summarized in their mechanisms, usages, merits and limitations. The challenges and further perspectives in the development of electrochemical sensors is also discussed.
双酚类物质（BPs）是一种广泛应用于塑料的有机化合物，属于内分泌干扰化学物质（EDCs）的一类，它们会对生物的内分泌系统产生干扰。BPs 会从食品接触材料（如塑料容器、金属罐中的环氧树脂涂料和热敏纸）中迁移出来，从而在人体中积累 BPs，导致不良的健康影响。因此，需要对食品中的 BPs 进行灵敏和选择性的检测。在已经探索的各种检测 BPs 的策略中，具有较高灵敏度和快速响应的电化学传感器是很有前途的。本文全面综述了用于食品中 BPs 传感的电化学方法，旨在为开发低成本、高精度和兼容性的传感器以实现对 BPs 的灵敏和选择性检测找到一个方向。本文根据识别剂、适体、酶、分子印迹聚合物和纳米材料等不同的电化学技术进行分类，讨论并总结了它们的作用机制、用途、优点和局限性。还讨论了电化学传感器发展所面临的挑战和进一步的展望。
