摘　　要：为建立食品接触材料中紫外吸收剂、塑化剂、抗氧化剂10种物质的气相色谱质谱高通量检测方法,试验优化(GCMS)了检测条件参数,并对市售78批次的食品接触材料中10种添加剂的迁移量进行测定。结果表明:气相初始温度120℃,以20℃/min的速率升温至300℃,色谱峰分离较佳,质谱部分采用选择离子扫描,收集离子扫描与全扫描数据;在0.1 mg/L与5.0 mg/L浓度范围内, 10种添加剂均具有很好的线性相关性(R>0.995), DINP检出限为0.05 mg/kg,其它9种添加剂BHT、BHA、TBHQ、DAP、DIBP、DBP、DEHP、BP、MBP的检出限均为0.01 mg/kg;对78批次样品进行测定,结果显示:在4%乙酸、70℃、2 h条件下,有7批次样品检出有添加剂(DIBP、DBP),检出率为8.98%;在异辛烷、70℃、2 h条件下,有26批次样品检出有添加剂(BP、DIBP、DBP、DEHP、BHA),检出率为33.3%;在去离子水、70℃、2 h条件下,未发现有添加剂检出。表明食品接触材料中添加剂在酸性及油脂性环境下迁移的风险较大。To establish gas chromatography mass spectrometry high-throughput detection method of 10 kinds of ultraviolet absorption agents, plasticizing agents, and antioxidants in food contact materials, the parameters（GCMS） test conditions were determined, and volume of migration of 10 kinds of additives in 78 batches of commercial food contact materials was determined. The results showed that chromatographic peak separation was better when initial temperature of gas phase was 120 ℃, and heat up to 300 ℃ at a rate of about 20 ℃/min. Mass spectrometry was performed by Selective Ion Monitoring, and ion scanning and full scan data were collected. Within the concentration range of 0.1 mg/L and 5.0 mg/L, well linear correlations were found in all 10 kinds of additives（R0.995）, the detection limit of DINP was 0.05 mg/kg, and the detection limits of BHT, BHA, TBHQ, DAP, DIBP, DBP, DEHP, benzophenone and 4-Methylbenzophenone were all 0.01 mg/kg. 78 batches of samples were determined. The results showed that DIBP and DBP were detected in 7 batches of samples on the condition of 4% acetic acid, 70 ℃ and 2 h, and the detection rates were 8.98%. Benzophenone, DIBP, DBP, DEHP and BHA were detected in 26 batches of samples on the condition of isooctane, 70 ℃ and 2 h, and the detection rates were 33.3%. No additives was detected on the condition of deionized water, 70 ℃ and 2 h. The results showed that the risk of additive migration in food contact materials was greater in an acidic and greasy environment.
