中文摘要：本研究采用液相色谱-大气压化学电离质谱仪(LC-APCI-MS)开发了一种定量检测宠物食品中玉米赤霉烯酮（ZEA）的分析法，并开展了实验研究。实验效度研究发现ZEA的平均回收率、重复率、再现率及HorRats值分别为99.0-102%、2.2-3.0%、5.6-6.6%和0.33-0.36。
外文摘要：An analytical method for quantifying zearalenone (ZEA) in pet foods using a liquid chromatograph-atmospheric pressure chemical ionization-mass spectrometer (LC-APCI-MS) was developed, and an inter-laboratory study was conducted. ZEA was extracted from pet food samples with aqueous acetonitrile. The extract was purified using a multifunctional column, MultiSep 226 Aflazon+, and analysed with LC-APCI-MS. The limit of quantification of ZEA by this method was estimated to be 0.2 mg/kg for dry and semi-dry pet foods, and 0.1 mg/ kg for wet pet food. The calibration curve of ZEA for this method showed linearity in the range of 0.1-10 ng of ZEA (0.01-1.0 mu g/ ml, 0.04-4.0 mg/ kg matrix). The mean recoveries, repeatabilities, reproducibilities, and the HorRats for ZEA from the inter-laboratory validation study were 99.0-102%, 2.2-3.0%, 5.6-6.6%, and 0.33-0.36, respectively.
