Infusion of lamb carcasses with 0.3M CaCl 2 resulted in acceleration of postmortem tenderization process. Control and treated animals had similar cathepsin B, H, and L activities. Various control groups had similar CDP‐I, ‐II and inhibitor activities, whereas these were all decreased in CaCl 2 infused animals. Hence, it was concluded that the activation of Ca 2+ ‐dependent proteases was responsible for the observed postmortem proteolysis and tenderization and, it seems unlikely that activity of these cathepsins is related to postmortem tenderization under conditions used in this experiment.
