This study was conducted to investigate the quality characteristics of low-fat pork patties containing fat replacers. Pectin(PE) and potato starch(PO) were added as fat replacers and physicochemical properties of the patties were evaluated after oven-roasting or pan-frying. Uncooked and cooked pork patties formulated with the fat replacers were higher in moisture and ash content and lower in fat content than those of the control. The cooking yield and reduction in diameter of the patties were significantly improved by the addition of PE or PO and oven-roasting exhibited a higher cooking yield and lower reduction in diameter than pan-frying (p<0.05). Water holding capacity(WHC) and fat retention were highest in the patties formulated with PE, while the control had the lowest WHC when cooked by oven-roasting. The Hunter L (lightness) values were not different among the patties but the Hunter a (redness) and b (yellowness) values of the low fat pork patties were higher than those of the control and oven-roasting produced higher redness values lhan pan frying. Hardness and brittleness were lowest in the patties with PE, while cohesiveness and springiness showed no difference among the patties (p<0.05). The sensory analysis results showed that the use of PE or PO improved die overall acceptability of the low-fat pork patties. After 30 days of storage at -20℃, pH and cooking yield decreased slightly, while hardness increased in all the patties.
