Title: Inhibitory effect of vinegars on the formation of polycyclic aromatic hydrocarbons in charcoal-grilled pork
Issue Date: 2020
Abstract: The effect of five different vinegars, applied as a seasoning, on the formation of polycyclic aromatic hydrocarbons (PAH) in charcoal-grilled pork loin was investigated. PAH were assayed using acetonitrile based-extraction and high-performance liquid chromatography with fluorescence detection. Unseasoned samples presented a mean value of 31.47 ng g(-1) of PAH4 (sum of benz[a] anthracene, chrysene, benzo[b]fluoranthene and benzo[a]pyrene), near the maximum established by European Union (30 ng g(-1)). Significant reduction (p < .05) of PAH4 formation was observed in meat samples sprayed with vinegar. Elderberry vinegar exhibited the highest inhibition (82%), followed by white wine vinegar (79%), red wine and cider vinegars (66%), and fruit vinegar with raspberry juice (55%). The total phenolic content and antioxidant activities of vinegars had a moderate negative correlation with PAH4 formation, and 3rd degree polynomial equations had the best fitting performance to explain this relation. Spraying meat with these vinegars prior grill is an easy-to-apply strategy to limit the exposure to PAH.
