چکیده انگلیسی
The postmortem calpain-11 role in ostrich muscle was investigated. Pairs of ostrich muscle (Iliotibialis cranialis) were excised from 32 ostrich carcasses in 3-h postmortem and randomly assigned into four treatments. The muscle was cut into 2.5-cm thick meat cores. The cores were incubated in 30â¯mM CaCl2, 30â¯mM EDTA, 90â¯mM NaCl, or control. The cores from the left-side carcasses were sampled after 0, 1, 2, and 3â¯days of incubation at 5â¯Â°C, while the right-side meat cores were taken at 1-day and 3-day incubation for shear force measurements. The results showed that the decrease in unautolyzed and total activities of calpain-11, desmin content and shear force was more rapid in CaCl2-incubated samples than in control, NaCl- and EDTA-incubated samples. Thus, present results suggest that in the absence of calpain-1, calpain-11 with an extensive activation by adding exogenous Ca2+ could enhance the postmortem proteolysis and tenderization of ostrich muscle.
