Key Points

To determine how pre-rigor freezing delays and skeletal attachments influence muscle shortening and resulting tenderness across various lamb muscles.
Evaluated tenderness in eight lamb muscles subjected to varying delay intervals (0 to 24 hours at 18°C) before freezer entry.
Tested the impact of physical restraint by severing the skeletal attachments at one end of selected muscles prior to carcass chilling.
Quantified the relationship between pre-rigor shortening and toughening across five distinct muscles.
Three muscles toughened substantially under early freezing but improved markedly in tenderness when pre-freezer delay at 18°C was increased from 10 to 16 hours.
Severing skeletal attachments significantly increased toughness in muscles that were normally tender or intermediate under early freezing, whereas naturally tough muscles showed little change.
Muscles exhibited identical potential to shorten and toughen, demonstrating that tenderness variations stem entirely from skeletal restraint limiting shortening rather than intrinsic muscle differences.
