This study aimed to evaluate the effect of wet ageing on chemical-physical characteristics of sirloin and bone-in rib eye steaks obtained from 18 months old young bulls and 27 months old heifers. A positive beef tenderization effect of wet ageing was observed with lower values constantly detected in the rib-eye samples and significantly lower shear force values showed in heifer steaks if compared to bulls. The pH values detected both in pre- and post-ageing samples fell in the normal range for meats. The water holding capacity of sirloin samples increased with ageing while in rib eye steaks, no significant differences were detected among samples taken before and after ageing. Meat ageing resulted in a decrease of cooking loss, while meat colour parameters were not influenced by ageing and fell within the normal range. An evident improvement of the sensorial quality of bone-in wet aged beef, especially in tenderness, was achieved.
