中文摘要: 建立熟肉制品中5种合成色素的高效液相色谱法测定方法。熟肉制品经过脱脂后提取色素，选择样品中5种色素的最大吸收波长用高效液相色谱仪分析测定。在0.10μg/mL～50.0μg/mL线性范围内，所得5种合成色素的回归方程均呈较好的线性关系（r＞0.999）。该方法的检出限为0.035μg/mL～0.040μg/mL，相对标准偏差在0.79%～1.30%之间。对样品进行加标回收试验，绝对回收率在91.5%～101.0%之间。本方法简便、快速、准确，适用于熟肉制品中合成色素的测定。
Abstract:To establish a HPLC method for the determination of 5 kinds of synthetic pigment in cooked meat products，the selection of the maximum absorption wavelength of 5 synthetic pigment in the samples was determined by high performance liquid chromatography analysis，after the degreasing of the cooked meat products and the pigment extraction.The obtained regression equations of 5 kinds of synthetic pigment showed a good linear relationship（r＞0.999）in 0.10 μg/mL-50.0 μg/mL linear range，with the detection limit of 0.035 μg/mL-0.040 μg/mL，and the relative standard deviation was between 0.79%to 1.30%.The samples were spiked with recovery experiment，and the absolute recoveries were in the range of 91.5%-101.0%.The method is simple，rapid，accurate，which is suitable for determination of the synthetic pigment in cooked meat products.
