摘要

建立了测定咖啡样品中EU优先多环芳烃的良好性能条件，以评价烘焙程度对咖啡豆中多环芳烃的影响以及冲泡方法对咖啡豆中多环芳烃转移到冲泡物中的影响。对咖啡产品中多环芳烃的消费风险也进行了评估。烘焙咖啡豆的多环芳烃含量顺序为:923.65 ng/g(深烘)> 132.20 ng/g(中烘)> 69.28 ng/g(浅烘)。咖啡机冲泡(设置在4 bar)时，咖啡冲泡中PAHs的释放量(PAHs含量为0.36 ~ 2.14 ng/g)高于一般用滴灌袋冲泡(PAHs含量为0.30 ~ 0.62 ng/mL)。商业煮咖啡和罐装咖啡产品的多环芳烃含量分别为0.32 ~ 1.23 ng/g和0.16 ~ 0.46 ng/g。咖啡冲泡和产品中多环芳烃的消费风险是低水平的关注。

The good performance conditions for determination of EU priority PAHs in coffee samples were established to evaluate the effects of roasting degree on the PAHs in coffee beans and the brewing methods on the PAHs transfer from coffee beans to their brews. The consumption risk of the PAHs in coffee products was also assessed. The PAHs levels of the roasted coffee beans were in the order: 923.65 ng/g (dark roast) > 132.20 ng/g (medium roast) > 69.28 ng/g (light roast). Compared with general brewing with the drip bag (PAHs content, 0.30-0.62 ng/mL in coffee brews), the coffee machine brewing (set at 4 bar) induced higher PAHs release into coffee brews (PAHs content, 0.36-2.14 ng/g). The PAHs amounts of the commercial brewed and canned coffee products were 0.32-1.23 ng/g and 0.16-0.46 ng/g, respectively. The consumption risk of the PAHs in the coffee brews and products is a low level of concern.
