This study was performed to evaluate physicochemical properties of model sausages with various levels of pressed cherry fruit extracts alone or in combination with tomato powders as a partial replacement of sodium nitrite. In study 1, physicochemical properties of model sausages were not affected by the addition of pressed cherry fruit extracts(p>0.05), except for Hunter L(lightness) and Hunter a(redness). Model sausages containing pressed cherry fruit extract(T1, 0.5% and T2, 1.0%) decreased lightness, whereas redness of REF(156 ppm sodium nitrite) was not different from T2(p>0.05). However, those with cherry fruit extract at 1% were proper to improve the hunter color values, especially redness values. In study 2, physicochemical properties of model sausages were not affected by the addition of pressed cherry fruit extract and tomato powders in selected nitrite contents, except for color and cooking loss(p>0.05). In color values, REF was the highest level, and T2, T4, and T5 was significantly low level in lightness (Hunter L). T2 was the highest value in cooking loss(%) among other treatments. The redness values(Hunter a) of T5(75ppm, nitrite, 1% pressed cherry fruit extract and 0.5% tomato powder) were not different from REF which had highest redness values(P<0.05). In conclusion, the combination of pressed cherry fruit and tomato powder might be considered as an alternative method to partially replace with sodium nitrite in pork model sausages.
