Extraction of a Fusarium mycotoxin zearalenone in edible oils

Abstract

  A simple, fast, accurate analytical method of Fusarium mycotoxin zearalenone (ZEA) from edible oils was developed by analyte-extension of the method for aflatoxins in oils. Oil samples were extracted with a mixture of acetonitrile and water (9 + 1, v/v) followed by the clean-up with a multifunctional column. ZEA content was determined by high-performance liquid chromatography with fluorescence detector (HPLC-FLD). The method was in-house validated for two matrices, blended oil and olive oil. The recovery rates were between 100.4% and 105.2 %, while relative standard deviations (RSDs) were between 0.9% and 2.3%.
