| 中文摘要: |
| 目的 研究果蔬用聚苯乙烯泡沫箱中挥发性有机物的迁移情况，对食物接触泡沫箱后的安全性进行评估。方法 采集不同来源的泡沫箱，先用乙酸(体积分数为4%)和乙醇(体积分数为10%)对其进行模拟液迁移实验，然后选取迁移量较高的挥发性有机物进行实物迁移实验，检测挥发性有机物的迁移量。结果 模拟液的迁移实验中检出间二甲苯、对二甲苯、邻二甲苯、苯乙烯、乙苯和1,3-丁二烯均有不同程度的迁移，并且体积分数为10%的乙醇作为迁移液时迁移值较高，苯乙烯在体积分数为10%的乙醇中迁移量最高;实物迁移实验中邻二甲苯在橙子中未检出，苯乙烯在橙子中的迁移量随着温度的升高，贮藏时间越长，迁移量越高。菜心检出了邻二甲苯，并且迁移量同样随着温度和时间的增加而呈现上升趋势，樱桃番茄中未检出挥发性有机物的迁移。结论 泡沫箱中苯乙烯、邻二甲苯在模拟液中的迁移量较高，并且在较高温度、较长时间接触橙子和菜心后可能会大量迁移，对人体健康产生风险。 |

| The work aims to study the migration of volatile organic compounds in polystyrene foam boxes for fruits and vegetables and evaluate the safety of food after contact with foam boxes. The foam boxes from different sources were collected, and 4% (volume fraction) acetic acid and 10% (volume fraction) ethanol were used to simulate liquid migration experiments. Then the volatile organic compounds with higher migration were selected for physical migration experiments to detect the migration of volatile organic compounds. Meta-xylene, p-xylene, o-xylene, styrene, ethylbenzene, 1,3-butadiene had different degrees of migration detected in the migration experiment of the simulated liquid, and 10% (volume fraction) ethanol has a higher migration value as a migration solution, styrene has the highest migration in 10% (volume fraction) ethanol; o-xylene was not detected in oranges in physical migration experiments, and the migration of styrene in oranges increases with the temperature, the longer the storage time, and the greater the migration high. O-xylene was detected in Chinese cabbage, and the migration amount also showed an upward trend with the increase of temperature and time. The migration of volatile organic compounds was not detected in cherry tomatoes. The migration of styrene and o-xylene in the foam box in the simulated liquid is relatively high, and they may migrate in large quantities after being exposed to oranges and Chinese cabbage for a long time at higher temperature, posing risks to human health. |
