With industrial progression, numerous new chemicals have emerged, many of which disrupt the human endocrine system. These endocrine-disrupting chemicals include parabens, benzophenone-UV filters, and bisphenol A (BPA). This study describes a method for simultaneously determining these compounds in 14 milk powders by solid-phase extraction (SPE) coupled with ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). The method shows that the limit of detection (LOD) for parabens and BPA is between 0.02 and 0.05 ng/g, while for benzophenones (BPs), it ranges from 0.02 to 0.24 ng/g. The recovery for parabens is between 100% and 105%, while for BPs, it's between 69% and 165%. Among the 14 milk powder samples analyzed, methylparaben (MeP) 86%, BPA 86%, and benzophenone 100% showed a notably higher detection rate and a geometric mean of 1.4, 1.1, and 3.4 ng/g, respectively. These results emphasize the widespread occurrence of MeP, BPA, and BPs and highlight the need for monitoring and risk assessment in food safety studies.
