Abstract
Proteolytic activation of endogenous muscle proteases, calpains and cathepsins, contributes to autolysis of fish myofibrils and concomitant softening of fillets during post-mortem storage. Calpains activity causes limited hydrolysis of myofibrils during initial days of post-mortem storage, whereas cathepsins in addition to proteolysis of major myofibrillar and associated proteins have the capacity to breakdown actin and myosin at later stages of post-mortem storage. Proteolysis of fish myofibrils post-mortem releases polypeptides and oligopeptides, some of which may demonstrate potential bioactive properties.
