摘要
建立同时测定肉及肉制品中9种水溶性人工合成着色剂含量的固相萃取-高效液相色谱法.方法采用氨水-乙腈-水溶液(1∶70∶29,v/v/v)提取,固相萃取小柱富集净化,多波长检测分析.肉及肉制品中9种水溶性人工合成着色剂在0.1~10 μg/mL浓度内线性关系良好,R2>0.9999,检出限为0.02~0.20 mg/kg,回收率为75.0%~103.3%,相对标准偏差(RSD)为0.10%~1.73%.研究结果表明,本方法前处理操作简单,各种色素分离度和回收率高,检测结果准确,且实验重现性好.
Abstract
A solid phase extraction-high performance liquid chromatography method was established for the simultaneous determination of nine water-soluble synthetic colorants in meat and meat products.The method used extraction with ammonian-acetonitrile-aqueous solution(1∶70∶29,v/v/v),solid phase extraction column for enrichment and cleanup,and multi-wavelength detection to analyze.In meat and meat products,nine water-soluble synthetic colorants had good linear relationships at the concentrations of 0.1~10 μg/mL,the correlation coefficient R2>0.9999,the limits of detection were 0.02~0.20 mg/kg,the recoveries were 75.0%~103.3%,and the relative standard deviations(RSD)were 0.10%~1.73%.The results showed that the method was simple in pre-treatment,high in the separation and recovery of various pigments,accurate in detection results,and good in experimental reproducibility.
