Physical characteristics and proximate and mineral composition of adipose tissue from free-range reared Swallow-belly Mangulica pigs from Vojvodina

Abstract

This study was carried out on 15 castrated male purebred Swallow-belly Mangulica pigs. The Swallow-belly Mangulica pigs were free-range reared on the territory of natural protected area 'Zasavica', Sremska Mitrovica. After chilling, back fat (lard) and leaf fat were excised from the right side of each carcass. Physical properties of adipose tissue were examined by determining the pH and colour (CIEL*a*b* values), while composition was examined by determination of the moisture, protein, total fat, total ash and mineral (phosphorous, potassium, sodium, calcium, magnesium, iron, zinc, copper, manganese) contents. There was no significant difference (P>0.05) between back fat and leaffat for any examined property, except for lightness (CIEL* value, P<0.001). Many significant relationships between examined quality properties were found.
