Abstract:Strip loins were removed from 10 bulls and 10 steers ~14 mo old and from 10 cows ≥ 44 mo. Samples were removed at 3, 7, 14, and 28 days postmortem. Shear-force values were measured. Sensory evaluation was done by a 15-member trained panel. Animal age and postmortem aging time had more influence on tenderness attributes than did sex of the animal. Increased postmortem aging time improved tenderness attributes regardless of sex or age.
Keywords:beef    aging    tenderness    shear force
