Food analysis is significantly important in monitoring food quality and safety for human health. Traditional methods for food detection mainly rely on benchtop instruments and require a certain amount of analysis time, which promotes the development of portable sensors. Portable sensing methods own many advantages over traditional techniques such as flexibility and accessibility in diverse environments, real-time monitoring, cost-effectiveness, and rapid deployment. This review focuses on the portable approaches based on carbon dots (CDs) for food analysis. CDs are zero-dimensional carbon-based material with a size of less than 10 nm. In the manner of sensing, CDs exhibit rich functional groups, low biotoxicity, good biocompatibility, and excellent optical properties. Furthermore, there are many methods for the synthesis of CDs using various precursor materials. The incorporation of CDs into food science and engineering for enhancing food safety control and risk assessment shows promising prospects.
食品分析对于监测人类健康的食品质量和安全具有重要意义。传统的食品检测方法主要依赖台式仪器，并且需要一定的分析时间，这促进了便携式传感器的发展。便携式传感方法在各种环境中的灵活性和可及性、实时监测、经济高效和快速部署等方面优于传统技术。本综述重点介绍了基于碳点（CDs）的用于食品分析的便携式方法。CDs 是一种零维碳基材料，尺寸小于 10nm。在传感方面，CDs 具有丰富的官能团、低生物毒性、良好的生物相容性和优异的光学性质。此外，还有许多使用各种前体材料合成 CDs 的方法。将 CDs 纳入食品科学和工程中，以增强食品安全控制和风险评估，具有广阔的前景。
