Concentration of phosphorous (P), potassium (K), sodium (Na), magnesium (Mg), calcium (Ca), iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn) was determined in the kidney tissue of sixty-nine pigs belonging to ten different genetic lines of pigs, produced in Vojvodina (northern Serbia). Phosphorous was determined by the standard spectrophotometric method. Metals were determined by the flame atomic absorption spectrometry after mineralization by dry ashing. The order of the minerals in the kidney tissue and their content ranges in mg/100 g was P (246–347, on average 287) > K (142–236, on average 189) > Na (102–187, on average 130) > Mg (17.8–36.6, on average 23.3) > Ca (15.9–27.7, on average 20.2) > Fe (5.32–10.42, on average 7.42) > Zn (2.15–4.10, on average 2.99) > Cu (0.62–2.15, on average 1.29) > Mn (0.16–0.30, on average 0.22). Genetic lines of pigs had no influence on mineral concentrations of kidney (P>0.05). The Vojvodian pig kidney showed slightly lower K, slightly higher P and Mn, and higher Ca contents, compared to the values reported in the literature.

Physical (pH and L*a*b* values) and chemical (moisture, protein, total fat, total ash, K, P, Na, Mg, Ca, Zn, Fe, Cu, and Mn) characteristics of offal consisting of the tongue, heart, lungs, liver, spleen, kidney, brain, and spinal cord of free-range reared Swallow-Belly Mangalica pigs were determined. Many significant differences were found among mean values of quality traits. However, except for a few cases, the determined offal quality traits were in the characteristic ranges reported in the literature. Lungs were high in pH24h (P<0.01) and L*a*b* values (P<0.01), as well as in moisture and Na concentration, and the lowest in K, Cu, and Mn. Tongue was high in total fat, and the lowest in pH24h, moisture (P<0.01), and total ash concentration. The highest levels of protein (P<0.01), Mg, Fe (P<0.05), Zn (P<0.01), and Mn (P<0.01) and the lowest of Na were found in liver. The darkest colour (lowest L* value), highest concentration of K, the lowest concentration of total fat and Ca were found in spleen. Finally, spinal cord was the highest in total ash (P<0.01), P (P<0.01), and Ca (P<0.05) and the lowest in protein, Mg (P<0.05), Fe, and Zn (P<0.01) concentration.

The aim of this paper was to examine the effect of chitosan coating with the addition of caraway essential oil and beeswax on lipid oxidation protection, as well as aroma and water content preservation of traditional dry fermented Petrovská klobása sausage.

During the entire storage period, TBARS index value in coated sausage was lower compared to the control (P<0.05). After two months of storage, TBARS index value in control and coated sausages were 0.94±0.04 mg kg–1 and 0.66±0.03 mg kg–1, while after seven months of storage, these values were 0.82±0.05 mg kg–1 and 0.67±0.02 mg kg–1, respectively. While content of saturated aliphatic aldehydes increased in control sausage (P<0.05), it remained unchanged in coated sausage during 7 months of storage. Lipid oxidation protective effect could be correlated to higher marks for aroma of coated sausage during the entire storage period (P<0.05). Coating slowed moisture loss of coated sausage compared to the control (P<0.05).
