摘要: 目的:了解方便面和方便米线中酞酸酯(PAEs)的污染状况。方法:样品用无水甲醇超声提取,上清液经干燥脱水过0.45μm滤膜过滤,采用毛细管气相色谱技术分析。结果:在采集的56袋市售方便面、25袋方便米线中检测到的邻苯二甲酸二丁酯和邻苯二甲酸二(2-乙基己基)酯的含量分别为:方便面调味酱料:未检出~59.38mg/kg、未检出~172.15mg/kg;方便面面饼:未检出~9.28mg/kg、未检出~1.08mg/kg;方便米线调味酱料:未检出~16.52mg/kg、未检出~44.75mg/kg。结论:方便面和方便米线食品存在不同程度的PAEs污染。

Abstract: Objective: To investigate the status of phthalate esters (PAEs) contamination in instant noodles and instant rice. Methods: Fifty-six bags of commercial instant noodles and 25 bags of commercial instant rice were sampled and extracted with absolute methanol by ultrasonic-assisted extraction. The extract was dehydrated and filtrated through a 0.45 μm membrane prior to capillary gas chromatographic analysis. Results: The levels of di-n-butyl phthalate (DBP) and di(2-ethylhexyl)phthalate (DEHP) ranged from 0 to 59.38 mg/kg and from 0 to 172.15 mg/kg in instant noodle seasoning sauce, from 0 to 9.28 mg/kg and from 0 to 1.08 mg/kg in instant noodle cake, and from 0 to 16.52 mg/kg and from 0 to 44.75 mg/kg in instant rice seasoning sauce, respectively. Conclusion: Instant noodles and instant rice were contaminated by PAEs to different extents.
