Postmortem role of calpain in Chinese and Wuzong goose muscles

The purpose of this study was to compare postmortem proteolysis and tenderization between Chinese and Wuzong goose breast muscles. Four months old Chinese (CG, n = 15) and Wuzong (WZ, n = 15) goose carcasses were vacuum-packaged 10 to 15 min postmortem and stored at 5°C. Breast (Pectoralis major) sa...

Sumario:The purpose of this study was to compare postmortem proteolysis and tenderization between Chinese and Wuzong goose breast muscles. Four months old Chinese (CG, n = 15) and Wuzong (WZ, n = 15) goose carcasses were vacuum-packaged 10 to 15 min postmortem and stored at 5°C. Breast (Pectoralis major) samples from each carcass were sampled at 0 (∼10 min postmortem), 1, 3, and 7 D of storage. Our results showed that the decrease in pH and calpain-1 activity was not different in CG and WG samples. However, the decrease in calpain-11 activity, desmin content, and shear force were more rapid (P < 0.05) in WZ than in CG samples. Our results indicate that postmortem proteolysis and tenderization of goose breast muscle were more extensive in WZ than in CG goose muscle.
