چکیده انگلیسی
The objective of this study was to evaluate the effects of callipyge (C) genotypes on quality attributes and oxidation stability of aged lamb loins. Only lambs possessing a wildtype maternal allele and a paternal callipyge allele (+/C) express a muscle hypertrophy phenotype. Seventeen lambs (7 months), consisting of all four possible callipyge genotypes (C/+, C/C, +/C and +/+), were harvested. Loins (M. longissimus thoracis) were separated from each carcass at 3Â days postmortem, cut into 3 sections, and randomly assigned into three aging periods (3, 6 and 9Â days). Genotype had no impact on proximate composition, mineral content, and pH of lamb loins (PÂ >Â 0.05). In terms of water-holding capacity, slightly increased purge/thaw loss of +/C lamb loins was observed (PÂ <Â 0.05), but cooking, drip and display weight losses were unaffected by callipyge genotype (PÂ >Â 0.05). The highest shear force was found at +/C lamb loins (PÂ <Â 0.05). +/C lamb loins showed initially less redness, but greater color stability during 7Â days of display compared to loins from the other genotypes. Heme iron content of +/C lamb loins was a significantly lower than the other genotypes. Genotype had no impact on lipid oxidation stability (PÂ >Â 0.05). Our results indicate similar quality attributes of lamb loins between non-callipyge phenotypes (C/C, C/+ and +/+) and suggest that callipyge lamb loins have superior color stability, while exhibiting lower tenderness compared to loins from non-callipyge phenotype lambs.
