This paperoverviews main aspects determining tendernesssuch structural and chemical composition meat,muscular contraction, biochemical postmortem changes(rigor mortis meant aging) general effects causedby industrial processing cooking freezing. Generalmethods for improving biochemicalactivity calcium ion dependent papain like cisteineproteases (CALPAIN) are reviewed.
