heat-processed meat products by HPLC-MS/MS using deep
eutectic solvent-assisted DLLME combined with magnetic
nanomaterials

ABSTRACT: This study presents a green and efficient method for the rapid detection of polycyclic aromatic hydrocar
bons (PAHs) in heat-processed meats. The method combines deep eutectic solvents (DES) with magnetic nanomaterials
(Fe3
O4
@C18
) to perform dispersive liquid-liquid microextraction (DLLME), followed by HPLC-MS/MS determination
of 16 priority PAHs. Under optimized conditions, the method showed excellent linearity (R2 ? 0.99) over the range of
0.1?50 ng/ml, with limits of detection between 0.01 and 0.06 ng/ml and recoveries of 80.9?102.4% (RSD < 8%). The
developed method exhibited high sensitivity and accuracy, and was successfully applied to commercial meat products,

sustainability, operational simplicity, and strong applicability for monitoring and risk assessment of PAHs in complex
food matrices.
