Abstract: Meat tenderness is known to be affected by sarcomere length (SL), proteolysis and collagen content (CC). 60 lambs were slaughtered and the 'Longissimus' muscle was sampled. Shear force (SF), SL, proteolysis (desmin, PSA) and CC samples were taken after the allotted aging periods (1, 7, and 14 days). Proteolysis explained a large part of the variation in tenderness (approximately 35%). Other factors (CC, SL) combined with proteolysis (PSA, desmin) explained just under 40% of the variation of meat tenderness. The main conclusion that can be drawn from this study is that ageing response i.e. post-mortem proteolysis is the dominant factor determining lamb loin tenderness.
