Research advances on determination methods for perfluorinated compound in food contact materials

Perfluorinated compounds mainly contain perfluorooctane acid (PFOA), perfluorooctane sulfonate (PFOS) and their salt compunds. Perfluorinated compounds are one of the persistent organic pollutants, which are most difficult to be degraded at present. Perfluorinated compounds are widely used in the textile, paper, leather and other industries for their efficient hydrophobic and oleophobic properties. However, they have toxicities such as reproduction toxicity, genetic toxicity and developmental toxicity, and they can enter into people’s food through food contact materials and threaten people’s health. This paper described the overview of perfluorinated compounds and the research progress on detection technologies for perfluorinated compounds in food contact materials.
