Microplastics (MPs), as a kind of plastic particles with an equal volume size of less than 5 mm, similar to PM2.5 in the air, are causing severe contamination issues in food. Along with the food chain accumulation, they have been confirmed to appear in daily foods and cause serious health risks to the organisms. However, there were no unifying national and local policies on separating, extracting, and detecting MPs in food, which is an essential and imperative early-warning strategy. This review carefully and comprehensively summarized the validated contaminated food, physical and chemical characteristics, extraction methods, traditional and rapid detection techniques, as well as degradation methods of MPs. We thoroughly analyzed the differences among these traditional strategies, and innovatively generalized the existing rapid detection techniques for MPs. Finally, the shortcomings of existing research were discussed, and the possibility of novel rapid and intelligent detection techniques for MPs in food was proposed.
微塑料（MPs）作为一种体积尺寸小于5毫米的塑料颗粒，类似于空气中的PM2.5，正在引发食品中的严重污染问题。随着食物链的积累，它们已被证实出现在日常食品中，并对生物体造成严重的健康风险。然而，在食品中微塑料的分离、提取和检测方面，尚无统一的国家和地方政策，而这是一项至关重要且势在必行的预警策略。本综述仔细且全面地总结了经过验证的受污染食品、微塑料的物理和化学特性、提取方法、传统及快速检测技术，以及微塑料的降解方法。我们深入分析了这些传统策略之间的差异，并创新性地归纳了现有的微塑料快速检测技术。最后，讨论了现有研究的不足之处，并提出了食品中微塑料新型快速智能检测技术的可能性。
