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
