| 中文摘要: |
| 目的 探究防老剂在食品塑料包装制品中的使用情况，以期建立食品塑料包装制品中防老剂(N-苯基-2-萘胺、1-萘氨基苯、乙氧基喹啉、橡胶防老剂DTPD、橡胶防老剂4010NA、防老剂ODA、防老剂H、N,N′-二苯基对苯二胺)残留量的高效液相色谱-串联质谱(HPLC-MS/MS)检测方法。方法 样品经三氯甲烷和甲醇提取、浓缩，甲醇复溶后，用高效液相色谱-串联质谱测定，外标法定量。结果 8种防老剂残留量为10.0～200.0 μg/L时线性关系良好(相关系数R2＞0.999)，定量下限为5.0 μg/kg。在10，20，100 μg/kg 3个加标水平下，8种防老剂的加标平均回收率为81%～116%，相对标准偏差小于等于3.77。结论 文中方法准确、高效、简单，可用于食品塑料包装制品中8种防老剂残留量定性定量测定。 |
| 英文摘要: |
| Through exploring the use of antioxidant in food plastic packaging products, an analytical method of determining residues of eight antioxidants (N-Phenyl-2-naphthylamine, N-Phenyl-1-naphthylamine, Ethoxyquin, 1,4-Benzenediamine, N-Isopropyl-N'-phenyl-1,4-phenylenediamine, Dioctyldiphenylamine, 1,4-Dianilinobenzene, N-(1,3-Dimethylbutyl)-N'-phenyl-p-phenylenediamine) by HPLC-MS/MS was established. The samples were extracted by chloroform and methanol, then concentrated and redissolved by methanol. The extract was analyzed by HPLC-MS/MS and quantified by external standard method. The linear ranges of eight compounds ranging from 10.0 to 200.0 μg/L with correlation coefficients(R2) more than 0.999, and the detection lower limits were 5.0 μg/kg. The average recoveries of eight compounds were ranging from 81% to 116% at three spiked concentration levels of 10, 20 and 100 μg/kg with relative standard deviations not more than 3.77. The method is accurate, simple and efficient, and can be used for qualitative and quantitative determination of residues of eight antioxidants in food plastic packaging products. |
