Mitochondrial functionality and beef colour: A review of recent research

  • 2019
  • Issue: 1
  • Volume: 49
R. Ramanathan, M.N. Nair, M.C. Hunt & S.P. Suman Page: 9 - 19

The bright-red colour of meat that consumers prefer depends on the depth of oxygen diffusion into the tissue and myoglobin oxygenation. Interestingly, both processes are influenced by mitochondrial activity in postmortem muscle. The transition of muscle metabolism from aerobic to…

Supranutritional supplementation of vitamin E influences mitochondrial proteome profile of post-mortem longissimus lumborum from feedlot heifers

  • 2018
  • Issue: 6
  • Volume: 48
C. Zhai, S.P. Suman, M.N. Nair, S. Li, X. Luo, C.M. Beach, B.N. Harsh, D.D. Boler, A.C. Dilger & D.W. Shike Page: 1140 - 1147

Supplementation of vitamin E improves beef colour stability by minimizing lipid oxidation-induced myoglobin oxidation. Mitochondria affect myoglobin redox stability, and dietary vitamin E influences mitochondrial functionality in skeletal muscles. Nonetheless, the influence of vitamin E on the mitochondrial proteome of…
