To evaluate the safety of food for pets, the migration of chemical substances from pet tableware was investigated by mass spectrometry. The presence of polymer additives Irgafos 168 and Erucamide were suspected based on mass spectra and were confirmed to be present in polypropylene tableware. The amount of substances migrated using simulated saliva was examined by liquid chromatography-mass spectrometry after solid phase extraction and purification. Photoionization was found to be suitable for the simultaneous determination of these substances. The detection limits of the established method were 0.019 μg/mL for Irgafos 168 and 0.022 μg/mL for Erucamide. Five different types of pet tableware purchased in local markets were examined and no analytes were detected in the simulated saliva using shaking extraction. In this study, the risk to pets from the substances migrated from pet tableware was considered to be sufficiently low.
为评估宠物食品的安全性，采用质谱法对宠物餐具中化学物质的迁移情况进行了研究。根据质谱怀疑存在聚合物添加剂Irgafos 168和芥酸酰胺，并证实它们存在于聚丙烯餐具中。固相萃取和净化后，采用液相色谱 - 质谱法检测了模拟唾液中迁移出的物质含量。发现光电离适用于同时测定这些物质。所建立方法对Irgafos 168的检测限为0.019μg/mL，对芥酸酰胺的检测限为0.022μg/mL。对在当地市场购买的五种不同类型的宠物餐具进行了检测，采用振荡萃取法在模拟唾液中未检测到分析物。在本研究中，认为宠物餐具迁移出的物质对宠物造成的风险足够低。
