Pesticide detection in food produce through bead mill homogenization and QuEChERS extraction

Pesticide detection in food produce through bead mill homogenization and QuEChERS extraction

The QuEChERS method, a solvent extraction technique introduced in 2003, is widely used for the extraction of multiple pesticides from samples; It has since been optimized to support a broad range of analytes. It starts with the comminution of samples, which can include the convenient and reliable use of bead-beating in solvent. This study describes the application of bead mill homogenization to simultaneously homogenize several samples for QuEChERS extraction for pesticide detection in common fruits and vegetables, with full homogenization achieved in 30 seconds for all assayed produce types in 50 mL tubes. Pesticides were then extracted and analyzed by LC-MS/MS.
