| 摘 要： | 建立了气相色谱法同时测定食品接触材料纸制品中双酚A,丁羟基茴香醚(BHA)、特丁基对苯二酚(TBHQ)、2,6-二叔丁基对甲酚(BHT)、2,4,6-三异丁基苯酚(TTBP)、2,2′-亚甲基双(4-乙基-6叔丁基酚)(AO425)共6种抗氧化剂的分析方法。纸制品加水浸泡,然后用乙酸乙酯—正己烷混合溶剂匀浆提取,考察了提取溶剂、提取方法对抗氧化剂提取效率的影响。提取液经毛细管气相色谱柱DM-5(30 m×0.25 mm×0.25μm)分离,氢火焰检测器(FID)检测,外标法定量。结果表明,在抗氧化剂添加量为10.0～50.0 mg/kg范围内,双酚A,BHA,TBHQ,BHT,TTBP和AO425在纸制品中的平均添加回收率分别为82%～104%,82%～103%,83%～102%,85%～104%,85%～104%,84%～104%,相对标准偏差(RSD,n=10)分别为5.3%～6.8%,4.9%～6.7%,4.6%～6.6%,53%～6.9%,4.7%～6.6%,4.5%～6.9%,BHA,BHT,TBHQ,TTBP,双酚A,AO425测定低限(信噪比>10)为10.0mg/kg,线性范围1.0～100.0 g/mL,相关系数大于0.999。

| Abstract: | A new method for the determination of 6 kinds of antioxidants,Bisphenol A,butylated Hydroxy anisole(BHA), tertiary butyl hydro quinone(TBHQ),butylated hydroxytoluene(BHT),TTBP and A0425 in plastic food package by gas chromatography-electron capture detection is developed.The plastic food package is immersed in the water,then are extracted by mixed solvent of Ethyl acetate and n-hexane with homogenation,separated by an HP-50 + chromatographic column(30 m×0.25 mm×0.25μm) and quantified by external standard method with an FED detector.The results indiated that the average recoveries of antioxidants are 82%～104%,82%～103%,83%～102%,85%～104%,85%～104%and 84%～104%for Bisphenol A,BHA,TBHQ,BHT,TTBP and A0425,respectively,at the spiking levels of 10.0～50.0 mg/kg;the orresponding relative standard deviations(RSD,n=10) are 5.3%～6.8%,4.9%～6.7%,4.6%～6.6%,5.3%～6.9%,4.7%～6.6%,4.5%～6.9%for Bisphenol A,BHA,TBHQ,BHT,TTBP and AO425,respectively and the limits of detection (S/N>10) are 10.0 mg/kg or Bisphenol A,BHA,TBHQ,BHT,TTBP and A0425,linear range is 1.0～100.0 g/mL,the correlation coefficient is more than 0.999. |
