摘要：Graphical abstractDisplay OmittedAbstractObjectivesIn the present work, the inhibitory effect of culinary herbsZa'atar(blend of thyme, sesame seeds and sumac) marinades on the formation of polar (quinoxalines, quinolines and pyridines) and non-polar (α-carbolines, β-carbolines, γ-carbolines and δ-carbolines) heterocyclic amines (HCAs) in cooked beef patties were investigated.MethodsThe beef patties were subjected to pan-frying under controlled temperature and time, HCAs analysis was carried out by solid-phase extraction (SPE) and ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).ResultsThe amounts of HCAs quinoxalines (0.74–2.88 ng/g), quinolines (0.54–0.75 ng/g), pyridines (1.66–6.32 ng/g), α-carbolines (Za'atar(control sample). In the results achieved after marination withZa'atarat different periods (1, 2, 4, 6, 12 and 24 h), HCAs yields (except β-carbolines) were steadily decreased with time (59.38 to 100%, 2–24 h). On contrary, β-carbolines levels were found to be radually increased with time (44.76%, 24 h).ConclusionsThe variation of HCAs formation occurred due to the presence of natural antioxidants inZa'atarwhich usually stimulate the oxidative effect, and thus leading to the reduction and/or formation of HCAs in cooked meat. The achieved HCAs values from this work could be applied to estimate the HCAs human intake globally and add toZa'atarin such types of food products that diminish the risk of HCAs exposure, and thus to get healthier food quality and security.
