Impact of Various Smoking Techniques on Polycyclic Aromatic Hydrocarbon (PAH) Formation in Dry-Cured Pork Neck (Buđola)

Abstract

Traditional meat products that are smoked may pose health risks due to polycyclic aromatic hydrocarbons (PAHs). Recently, concerns have grown about the health implications of meat products smoked under traditional, uncontrolled conditions. This study compares the levels of polycyclic aromatic hydrocarbons in specimens of the dry-cured meat product “Buđola” made in traditional smokehouses versus industrial chambers. PAHs were measured upon completion of smoking and when the production was complete. The findings indicate that traditional smoking methods lead to higher PAH contamination compared to industrial methods. Among the 16 PAHs analyzed, 10 (NA, AL, FL, ANT, PHE, FLT, BA, PR, BBF, BKF) were detected in traditionally smoked “Buđola” samples, whereas only 2 (NA, AL) were found in samples smoked by industrial methods. The BP levels in all samples were undetectable. PAH4 levels in industrial smoked “Buđola” were below the quantification limit, while those in traditional products were 28.77 μgkg−1 for the surface layers and 21.14 μgkg−1 for inner layers. The total PAH16 content ranged from 4.32 μgkg−1 to 3587.83 μgkg−1. The inner layers had lower concentrations of overall and specific PAHs in relation to the product surface. The results suggest that, from a health perspective, industrially produced “Buđola” is safer for consumption than the product smoked in uncontrolled conditions.
