Abstract
High-performance liquid chromatography (HPLC) and ultra-performance liquid chromatography (UPLC) were compared to validate a method for determination of zearalenone (ZON) in noodles, cereal snacks, and infant formulas. The limits of detection and quantification in HPLC and UPLC were found to be 4.0 and 13.0 μg kg(-1) and 2.5 and 8.3 μg kg(-1), respectively. The average recoveries of ZON by HPLC and UPLC ranged from 79.1% to 105.3% and from 85.1% to 114.5%, respectively. The measurement uncertainties of the two methods for ZON determination were within the maximum standard uncertainty. The two methods showed that the levels of ZON in 163 naturally contaminated samples ranged from 4.3 to 8.3 μg kg(-1) by HPLC and 3.1 to 17.6 μg kg(-1) by UPLC. These findings indicate that either method is suitable for the determination of ZON in noodles, cereal snacks, and infant formulas, but UPLC gives faster results with better sensitivity.Entities:
