Abstract

Cilj istraživanja bio je odrediti koncentracije policikličkih aromatskih ugljikovodika (PAH) u dimljenom pršutu nakon faze zrenja u trajanju od 12 i 18 mjeseci. Istraživanje je provedeno na uzorcima dva mišića pršuta, musculus biceps femoris (BF) i musculus semimembranosus (SM). Prisutnosti PAH spojeva u istraživanim mišićima određena je metodom visoko učinkovite tekućinske kromatografije s flouroscentnom detekcijom (HPLC-FLD). Rezultati istraživanja pokazali su da se PAH spojevi više akumuliraju u mišiću SM zbog svog vanjskog položaja odnosno veće izloženosti vanjskim faktorima, a ponajprije dimljenju. Također, ovo istraživanje je dovelo do zaključka da su se koncentracije većine PAH spojeva, nakon faze zrenja od 18 mjeseci, značajno smanjile u oba mišića. Koncentracije benz(a)pirena (BaP) i PAH4 (BaP, BaA, BbF, Chr), koji mogu biti potencijalno štetni za ljudsko zdravlje, nisu prešle vrijednosti koje je propisala Europska komisija za mesne proizvode, te je ovako industrijski proizveden Dalmatinski pršut siguran za konzumaciju u prehrani.

Abstract (english)

The aim of the research was to determine the concentrations of polycyclic aromatic hydrocarbons (PAH) in smoked dry-cured ham after the ripening phase for 12 and 18 months. The research was conducted on samples of two ham muscles, musculus biceps femoris (BF) and musculus semimembranosus (SM). The presence of PAH compounds in the investigated muscles was determined by the method of high-performance liquid chromatography with fluorescent detection (HPLC-FLD). The results of the research showed that PAH compounds accumulate more in the SM muscle due to its external position, i.e. greater exposure to external factors, primarily smoking. Also, this research led to the conclusion that the concentrations of most PAH compounds, after the ripening phase of 18 months, significantly decreased in both muscles. The concentrations of benz(a)pyrene (BaP) and PAH4 (BaP, BaA, BbF, Chr), which can be potentially harmful to human health, did not exceed the values prescribed by the European Commission for meat products, and thus industrially produced Dalmatian dry-cured ham is safe for consumption in the diet.
