Abstract This work presents a strategy for quantitating polycyclic aromatic hydrocarbons (PAHs) in smoked paprikasamples. For this, a liquid chromatographic method withfluorimetric detection (HPLC-FLD) was optimized. To resolve some interference co-eluting with the target analytes, the second-order multivariate curve resolution-alternating least-squares (MCR-ALS) algorithm has been employed combined with this liquid chromatographic method. Among the eight PAHs quantified(fluorene, phenanthrene, anthracene, pyrene, chrysene, benzo[a]anthracene, benzo[b]fluoranthene, and benzo[a]pyrene) byHPLC-FLD, only in the case offluorene, pyrene, and benzo[b]fluoranthene was it necessary to apply the second-order algorithmfor their resolution. Limits of detection and quantitation were between 0.015 and 0.45 mg/kg and between 0.15 and 1.5 mg/kg,respectively. Good recovery results (>80%) for paprika were obtained via the complete extraction procedure, consisting of anextraction from the matrix and the cleanup of the extract by means of silica cartridges. Higher concentrations of chrysene,benzo[a]anthracene, benzo[b]fluoranthene, and benzo[a]pyrene were found in the paprika samples, with respect to the maximalamounts allowed for other spices that are under European Regulation (EU) N°2015/1933
