In this study, pro-caspase 3 was factors influencing the conversion of muscle not activated during postmortem storage and to meat and meat quality. In living muscle caspase 3 activity was not correlated with tissue, HSP such as alpha β-crystallin, Warner-Bratzler shear force in beef longis- HSP20, and HSP27 have a homeostatic func- simus.
