摘 要:利用气相色谱串级质谱(GC/MS/MS)法定性定量鉴定食品中染料苏丹红一号,建立了离子阱气相色谱一质谱联用仪分析食品中苏丹红一号染料的方法。结果表明,苏丹红一号在0.045~0.90mg·L^-1浓度范围内呈线性关系,相关系数为0.9990,检测下限为0.0045mg·kg^-1,回收率在83.1%~103.2%之间。方法具有样品预处理简单、灵敏度高、检出限低于现行国家标准水平,确证能力强等特点,满足食品中苏丹红一号的定性定量监测。Ion-trap gas chromatography in hyphenation with MS/MS (in series) was applied to the identification and determination of sudan I in foodstuffs. Linear relationship between the peak area and concentration of sudan I was obtained in the range of 0. 045-0. 90 mg · L^-1 (r=0. 999 0), with a detection limit of 0. 004 5 mg· kg^-1. Test for recovery was performed by addition of 0. 008 mg · kg^-1 of sudan I to samples of chilli oil and chilli sauce, and recoveries in the range 83.1%--103. 2% were obtained. The proposed method was proved to have the specific features of simple in sample pre-treatment, high-sensitivity and having a lower detection limit than that required by GB standard, and suitable to be used for analysis of sudan I in foodstuffs.
