Zusammenfassung:A new method for the determination of zearalenone in edible oils with size exclusion chromatography (SEC) followed by LC-MS/MS as well as HPLC-FLD was developed and validated. By using the LC-MS/MS determination no further clean up step is necessary after the SEC. The correlation coefficient of 0.999 for the two detection systems is acceptable. In this research 77 edible oils were analyzed. The mean average value of 38 corn germ oils was 169 μg/kg, the maximum value amounted up to 921 μg/kg.[PUBLICATION ABSTRACT]
