Title

Effect of process of smoking meat products from pork showing with different initial quality on content of polycyclic aromatic hydrocarbons

Abstract

Under the research study, the effect was determined of the process of smoking meat products from meat of different initial quality on the content of polycyclic aromatic hydrocarbons (PAHs). The amount of PAHs was determined in coarse-and fine-minced cured meat products (ham sausages, ‘bockwurst’ type sausages) before they were smoked (forcemeat) and after the completed smoking process (final products). Meats of different fatty acid profiles were used to produce meat products; their fatty acid profiles differed, because fat from different fat sources was utilized to feed porkers. 21 different types of PAHs were determined and identified, and the contents of bezno[a]pyreneand, chrysene, benzo[a]anthracene, and benzo[b]fluoranthene) were particularly accurately analysed. It was found that the smoking of meat products contributed to the increase in the content of individual PAH from ca. 22 to 40 % compared to their contents in the products before smoking. It was also proved that the type of fat added to fodders for porkers used, next, as a raw material to produce cured meat products, significantly impacted the amount and type of PAHs in final meat products. The addition of linseed oil and fish oil in fodders for porkers contributed to the change in the fatty acid profile of meat; this fact encouraged the formation of a higher total amount of PAHs including the so-called heavy PAHs. The content of B[a]P in the products analysed did not exceed the limit value of 5 μg/kg, and the total of 4 PAHs from the ‘heavy group’ did not exceed the enforced, compulsory value of 30 μg/kg; this confirmed that the smoking parameters chosen were appropriate.
