Pretreatment technology and testing methods in food of parabens

Paraben is a broad spectrum preservative which can be used in food so that prevent food spoilage effectively and prolong shelf life. The application progress of pretreatment technology such as the direct dilution method, an organic solvent, ultrasonic assisted method, solid phase extraction, solid phase microextraction and gas chromatography, liquid chromatography, capillary electrophoresis three kinds determination in food paraben detection were reviewed detailedly, the principle, features and results of different pretreatment technologies and determination were also summarized and analyzed. Finally, the future of development of food paraben pretreatment technologies and determination were also previewed.
