Abstract
The objective of this study was to elucidate a relationship between some endogenous proteinases and their inhibitors in four different goat muscles during postmortem storage. Samples were taken from the longissimus dorsi (LD), biceps femoris (BF), semimembranosus (SM) and semitendinosus (ST) muscles stored up to 20 days postmortem at 5C. Activities of calpain-I, calpain-II, calpastatin, cathepsins (B, B+L, H and D) and cystatin(s) were determined. Decreases in calpain-I and calpastatin activities were significantly more than that of calpain-II activity. The cathepsin B, B+L, H and cystatin level were found to fall by 9-35% after 20 days, whereas the cathepsin D showed 11-17% decline in all the muscles. Thus changes in muscle proteinases and their inhibitors during postmortem storage differ and the results may shed light on their role in myofibrillar proteolysis and goat meat tenderization.
