Abstract: This study was a survey of estrogenic mycotoxin zearalenone (ZEA), which dangerously causes endometrial hyperplasia and cancer of esophagus in human body, method with an immuno-affinity column for clean-up. Before the measurement of the confirmed sample, the HPLC method was validated using a blank corn kernel matrix. The average recovery of blank corn kernel spiked with ZEA at levels of 100-550 mg/kg was 98.2%. The detection was confirmed by fluorescence spectral scanning throughout the chromatographic running. The method’s limitation of the detection was 3 mg/kg for ZEA in corn samples and the linear range applicable for analyses was 5-700 mg/kg of ZEA. Of 17 samples confirmed by HPLC, 14 samples were observed to be contaminated in a comparable range from 8.0 to 301 mg/kg. The comparative analysis of 17 positive of corn kernel samples used in ELISA and HPLC methods showed a sensitive correlation (R2=0.9538). |
