Abstract
ABSTRACTLongissimus muscle (loin section) was removed from each side of 24 pork carcasses within 20 min postmortem. Each muscle was divided in half (N = 96 sections), vacuum packaged and allotted to one of four treatments: (1) normal chilling, (2) propylene glycol immersion, (3) crust freezing, or (4) high temperature conditioning and four storage intervals (N = 6) or 0, 7, 14 or 28 days. Rapid chilling with propylene glycol increased (P<0.05) purge. Shear force values were increased when loins were rapidly chilled (P<0.05) but few sensory differences were observed. Off‐odor scores increased (P<0.05) with increasing storage time. Normal chilling resulted in lighter muscle color scores than rapidly chilled loin sections. Rapid chilling does not have a beneficial effect on palatability or shelf life of hot‐processed fresh pork.
