摘要：
The usefulness of myofibril fragmentation index (MFI) in predicting shear force of cooked meat was studied on muscle samples obtained immediately after death and aged or after aging the muscle in the intact carcass for about 7 days. The MFI values of cores obtained at the time of death (MFIO) of the animal were lower than those obtained after aging the meat (MFIA) in the intact carcass (69.18 vs. 81.38). However, correlations between MFI values with shear force values were similar for each sampling procedure (MFIO, r = ‐0.57; MFIA, r = ‐0.60). Results indicate that the biopsy of animals for MFI observations could possibly be useful in estimating tenderness. Copyright © 1990, Wiley Blackwell. All rights reserved
