Abstract
ABSTRACTForty‐six steer carcasses were used to evaluate shear force values (SFV) for triceps brachii (TB) and psoas major (PM) muscles from sides assigned to three treatments: (1) chilled at 2–4°C for 48 hr (C); (2) hot boned 2 hr postmortem (HB); and (3) electrically stimulated 1 hr postmortem and hot boned 2 hr postmortem (ESHB). Some steaks were cut and frozen immediately after muscle excision or after 6 days of aging, and some were blade tenderized. HB and ESHB steaks had equal or smaller SFV relative to C after aging the TB and PM muscles; however, this was not true when TB steaks were cut after muscle excision. Electrical stimulation or blade tenderization did not improve HB.
