Abstract

Fresh pork loins were cut for three replications and randomly assigned to one of seven treatments: 1) polyvinylchloride (PVC) packaged, 2) vacuum packaged (Vac-pack), 3) 0.2 mL of Tris-Buffer, 4) 0.2 mL of high leghemoglobin high pH (HLbHpH), 5) 0.2 mL of high leghemoglobin low pH (HLbLpH), 6) 0.2 mL of low leghemoglobin high pH (LLbHpH), and 7) 0.2 mL of low leghemoglobin low pH (LLbLpH). Treatments 3 through 7 also were vacuum packaged. Leghemoglobin (Lb) protein treatments improved (P<0.05) the visual color of vacuum packaged pork at the point of purchase. CIE L* values were not affected by HLbHpH, LLbHpH or LLbLpH treatments. However, the HLbLpH treatment was lighter (PO.05) sensory or objective color, pigment state, purge or total psychrotrophic aerobic bacterial counts (TPC) throughout the study. Lb treatments TPC were lower (P
