Abstract

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 pH_24h (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 pH_24h, 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.
