Abstract

The determination of eight polycyclic aromatic hydrocarbons (PAHs) in food was performed using a QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) method, followed by GC–MS. PAHs were extracted using acetonitrile, followed by purification using various methods involving different combinations of sorbents. The validation was conducted using a variety of food matrices. Calibration curves for the 8 PAHs demonstrated remarkable linearity (R2 > 0.99). The limits of detection (LODs) ranged from 0.006 to 0.035 µg/kg, and the limits of quantification (LOQs) ranged from 0.019 to 0.133 µg/kg. In all food matrices, recoveries ranged from 86.3 to 109.6% at 5 µg/kg, 87.7 to 100.1% at 10 µg/kg, and 89.6 to 102.9% at 20 µg/kg, with precision values between 0.4 and 6.9%. In different food matrices, the highest levels were observed in soybean oil, followed by duck meat and canola oil.

食品中多环芳烃气相色谱-质谱分析QuEChERS方法的建立
采用QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe)方法,结合气相色谱-质谱法(GC-MS)测定食品中8种多环芳烃(PAHs)。用乙腈提取多环芳烃,然后用不同的吸附剂组合进行纯化。使用多种食品基质进行验证。8种多环芳烃的校准曲线呈显著的线性关系(R2 > 0.99)。检出限为0.006 ~ 0.035µg/kg,定量限为0.019 ~ 0.133µg/kg。在5µg/kg条件下,加样回收率为86.3 ~ 109.6%;在10µg/kg条件下,加样回收率为87.7 ~ 100.1%;在20µg/kg条件下,加样回收率为89.6 ~ 102.9%,精密度为0.4 ~ 6.9%。在不同的食物基质中,豆油的含量最高,其次是鸭肉和菜籽油。

期刊介绍: The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
