Ractopamine is a beta-adrenergic agonist that increases leanness and carcass weight in finishing pigs. Our previous study observed that dietary ractopamine increased the abundance of several glycolytic enzymes in the sarcoplasmic proteome of post-rigor pork longissimus thoracis muscle. Pork semimembranosus…

Intramuscular variation in mitochondrial functionality of beef semimembranosus

  • 2017
  • Issue: 5
  • Volume: 47
M.N. Nair, R. Ramanathan, G. Rentfrow, & S.P. Suman Page: 635 - 639

Intramuscular color stability variations in beef semimembranosus have been reported previously. Mitochondria remain biochemically active in postmortem muscle and can influence fresh beef color stability. However, the role of mitochondrial functionality in intramuscular color variations in beef semimembranosus is yet…
