Nowadays, the widespread distribution of microplastics (MPs) in various foods has received much attention. In this study, eggs were purchased as samples from local supermarkets to detect and analyze the presence of MPs. The digestion method was optimized for eggs to better isolate MPs, which proved MPs indeed exist in eggs, and the average content was 11.67 ± 3.98 particles/egg. The shape and size range of most MPs were spherical and 50-100 μm. The infrared results showed that the main type of MPs in eggs was polyethylene. The number of MPs in egg yolk was higher than that in egg white, and there was no significant change after cooking. In addition, the daily human intake of MPs was estimated. Therefore, the results of this study provided a background for the current status and pollution of MPs in eggs, and proposed the necessary control and preventive measures to avoid this situation.

如今，微塑料（MPs）在各种食品中的广泛分布受到了广泛关注。在这项研究中，鸡蛋作为样品从当地超市购买，以检测和分析 MPs 的存在。对鸡蛋的消化方法进行了优化，以更好地分离MPs，证明鸡蛋中确实存在MPs，平均含量为11.67±3.98个/蛋。大多数 MPs 的形状和尺寸范围是球形和 50-100 μm。红外结果表明鸡蛋中MPs的主要类型是聚乙烯。蛋黄中 MPs 的数量高于蛋清中的 MPs，烹调后无明显变化。此外，估计了人类每日摄入的 MPs。因此，本研究结果为鸡蛋中 MPs 的现状和污染提供了背景，
