摘要:

本实验利用多种抑制乳化的方法将浊点萃取直接应用于食用油中的多环芳烃(PAHs)的预浓缩过程,在完全去除有机溶剂的使用,降低成本的同时,明显提升了浓缩能力,为食用油中痕量PAHs 的HPLC 检测提供了一种低价高效、环境友好的预浓缩方法。

Abstract:

Food safety is always paid lots of attentions, and the detection of polycyclic aromatic hydrocarbons (PAHs) is a very important step for the control of edible oil. In this study, the cloud point extraction was successfully applied in the preconcentration process of trace-level PAHs in edible oil. Compared to the traditional method, this new method totally avoids the usage of organic solvent, decreases the cost and improves the pre-concentration capability.

Key words: edible oil, polycyclic aromatic hydrocarbons, cloud point extraction, emulsion
