2019年上海市微波食品包装中邻苯二甲酸酯类塑化剂迁移风险监测

目的 评估微波食品包装中的邻苯二甲酸酯类(phthalic acid esters, PAEs)塑化剂至食品中的迁移风险进行。方法 采集90批次微波加热食品, 依据GB 31604.30-2016《食品安全国家标准 食品接触材料及制品中邻苯二甲酸酯的测定和迁移量的测定》, 采用气相色谱-质谱法(gas chromatography-mass spectrometry, GC/MS)对样品中的PAEs含量进行检测, 并考察样品中PAEs的迁移风险。结果 90批次微波加热食品包装中, 共计有18批次样品中检出PAEs增塑剂, 检出率为20%。其中15批次样品检出含量在0~10 mg/kg范围内, 最高检出含量为29.86 mg/kg。迁移实验未检出有塑化剂的迁移。结论 2019年上海市微波食品包装引入塑化剂污染的风险较低, 正常使用过程中迁移风险较小。

Risk monitoring of phthalate plasticizer migration in Shanghai microwave food packaging in 2019

Objective To evaluate the migration risk of the phthalic acid esters (PAEs) from the food packaging materials suitable for microwave heating. Methods Totally 90 batches of food packaging materials suitable for microwave heating were collected. According to GB 31604.30-2016 National food safety standard-Determination of phthalates in contact materials and products of food and determination of migration amount. The content of phthalic acid esters (PAEs) in the samples was detected by gas chromatography-mass spectrometry (GC/MS), and the migration risk of PAEs in the samples was examined. Results A total of 18 batches of the 90 batches were found to have PAEs, the detection rate was 20%, in which the content of PAEs in 15 batches were in the range of 0~10 mg/kg, and the highest content was 29.86 mg/kg. The migration experiment did not detect the migration of plasticizer. Conclusion Food packaging materials suitable for microwave heating in Shanghai in 2019 has a low risk of introducing plasticizer contamination, and the risk of migration during normal use is small.
