Notes:
The objective of this study was to evaluate sodium lactate (SL; 0, 1, 2 or 3%) and sodium polyphosphate (SP; 0, 0.1, 0.2 or 0.3%) effects on lipid oxidation and color characteristics of precooked pork patties during frozen storage. Ground pork was mixed with SL and/or SP, stuffed, frozen, sliced and cooked from the frozen state, packaged and held frozen for 14 weeks. Samples containing SP had lower TBARS, regardless of SL content. SL decreased pH, a* and b* values and red color (R630–R580). L* value, hue angle, pork flavor, saltiness, and juiciness increased as SL increased. A moderate correlation occurred between SL and TBARS. SP decreased hue angle, cook loss, and rancid flavor and increased pH, b* value, pork flavor, saltiness, and juiciness. Storage time decreased a* value, red color and juiciness, while saltiness, alkalinity, and rancid flavor scores increased. Based on both physical and sensory characteristics, optimum combinations appear to be 3% SL and 0.2–0.3% SP.
