Notes:
The proteolytic breakdown of the major contractile proteins of bovine longissimus muscle was examined during postmortem storage by sodium dodecyl sulfate (SDS) polyacrylamide gel electrophoresis. Samples of muscle stored at 4°C for 14 days exhibited little proteolysis of the major contractile proteins; however, samples stored at 37°C for 1 day showed significant degradation of myosin heavy chains and almost complete proteolysis of this protein by day 14. Major degradation products of the myosin heavy chains included a series of polypeptides having molecular weights between 145,000 and 125,000. These experiments demonstrate that substantial degradation of the myosin heavy chain and other muscle proteins can occur during the storage of meat, and this phenomenon was highly temperature dependent.
