    摘要:

    建立以二甲基亚砜作为提取溶剂,冷冻离心提取净化食品中的苯并[a]芘和苯并[e]芘,高效液相色谱—荧光法检测的方法。替代传统的固相萃取小柱净化方式,能更快速、高效、准确检测食品中苯并[a]芘和苯并[e]芘的含量。2种目标物在0.5~1000ng/mL范围内呈现良好线性关系,在1~100ng/g添加量下,回收率为89.0%~91.3%,相对标准偏差为1.19%~1.29%;仪器检出限为0.01ng/mL,植物油脂方法检出限为0.05ng/g,肉制品和动物油脂方法检出限为0.02ng/g。该方法测定动植物油脂和肉制品中的苯并[a]芘和苯并[e]芘方便、快捷,适用于批量化检测。

    Abstract:

    Benzo [a] pyrene and benzo [e] pyrene in food was extracted and purified by refrigerated centrifugation with dimethyl sulfoxide as solvent and analyzed by HPLC-fluorescence detection method. This method can replace the traditional solid-phase extraction column purification method, which is faster, more efficient and accurate in the detection of benzo [a] pyrene and benzo [e] pyrene content. Both target object showed a good linear relationship within range of 0.5~1000ng/mL, when addition was 1~100ng/g, the recovery rate was 89.0%~91.3%, and the relative standard deviation was 1.19%~1.29%; the detection limit was 0.01ng/mL, vegetable fat detection limit was 0.05ng/g, meat and animal fat detection limit was 0.02 ng/g. This method is faster and more convenient in the detection of benzo [a] pyrene and benzo [e] pyrene in animal, vegetable fat and meat products, which is suitable for batch detection.
