Display life of frozen lamb chops was unaffected by breed or sex. Chops shrink-wrapped in oxygen permeable film had a longer display life than those vacuum packaged in a film of low oxygen permeability. Chops cut from frozen loins, then packaged had a significantly longer display life than chops cut from chilled loins, packaged, and then frozen. Ram lamb chops had significantly higher pH values than those from wethers and ewes. Chops from Romney-cross lambs had lower pH values than those from Coopworth-cross and Perendale-cross lambs. Meat pH decreased slightly but significantly during storage.
