| 目的 研究食品接触材料中壬基酚和辛基酚的含量和迁移量的情况，并分析食品暴露风险。方法 采用液相色谱-质谱联用法建立食品接触材料中壬基酚和辛基酚含量和迁移量的检测方法，并对相关检测数据进行统计分析。结果 在优化条件下，壬基酚和辛基酚在5～200 μg/L范围内线性关系良好，相关系数均大于0.999，壬基酚和辛基酚含量和迁移量的检测方法定量下限分别为0.1 mg/kg和10 μg/kg，在添加水平为10，100，200 μg/L时，样品中壬基酚和辛基酚含量的平均加标回收率为85.6%～89.2%，迁移量的回收率为94.3%～100.6%，相对标准偏差均小于15%。对30批次保鲜膜和复合包装袋样品进行检测，结果显示，6批次样品检出壬基酚或辛基酚，占总体样品的20%；其中1批次样品检出壬基酚迁移量，占阳性样品的16.7%。结论 保鲜膜和复合包装袋可能含有壬基酚和辛基酚，且容易迁移到食品模拟物中，迁移量随着温度的升高和时间的延长而增加。保鲜膜和复合包装袋中的壬基酚和辛基酚存在一定风险，应引起足够重视。 |

| The work aims to study the content and migration of nonylphenol and octylphenol in food contact materials and analyze the risk of food exposure. The method used to determine the nonylphenol and octylphenol content and migration by liquid chromatography-mass spectrometry was established, and the related test data were analyzed statistically. Under optimized condition, the nonylphenol and octylphenol were in good linear relation within the range of 5~200 μg/L. The correlation coefficients were greater than 0.999. The lower limits of quantitative for the content and migration detected were 0.1 mg/kg and 10 μg/kg, respectively. The average recoveries of standard addition at three spiked levels of 10, 100 and 200 μg/L were 85.6%~89.2% and 94.3%~100.6% for content and migration determination, respectively. The relative standard deviation for both content and migration determination was less than 15%. 30 batches of plastic wrap and composite packaging bag samples were tested. The results were as follows: 6 batches of samples were detected containing nonylphenol or octylphenol, accounting for 20% of the total samples. In these 6 batches of samples, the result of nonylphenol migration in 1 batch of samples was positive, accounting for 16.7%. The nonylphenol and octylphenol may be contained in plastic wrap and composite packaging bags, and were easy to migrate to food stimulants. The migration increases as the temperature rise and time extension. There is a certain risk of nonylphenol and octylphenol in plastic wrap and composite packaging bags, which should be taken seriously. |
