This study was conducted to determine the effect of pH adjustment and addition of sodium chloride (NaCl) on quality characteristics of pork leg surimi. The pork leg surimi was manufactured with one of following pH 3.0 or pH 11.0 adjustment and contained 2% NaCl or not; C (Alaska pollack surimi, two times washing, 0% NaCl), T1 (pork leg surimi pH 3.0 adjustment, 0% NaCl), T2 (pork leg surimi, pH 3.0 adjustment, 2% NaCl), T3 (pork leg surimi, pH 11.0 adjustment 0% NaCl), T4 (pork leg surimi, pH 11.0 adjustment, 2% NaCl). The and W values was increased with increasing of pH value, but the and values lower. The W values were higher (p<0.05) as addition of NaCl, but and values were lower. In textural properties, the cohesiveness was increased with increasing of pH value, however with the exception of springiness all traits were higher (p<0.05) as addition of NaCl. The breaking force and gel strength was increased with increasing of pH value. The breaking force, gel strength and breaking force u deformation were higher as addition of NaCl, but shear force lower. In sensory evaluation, the tenderness was increased with increasing of pH value and all traits of sensory evaluation also were higher (p<0.05) as addition of NaCl. There were no differences in interaction of pH adjustment and without or with NaCl on color, textural properties, breaking force, deformation, gel strength, shear force and sensory evaluation of pork leg surimi. The color, textural and physical characteristics and sensory evaluation ot T2 and T4 were similar to treatment C. Therefore, the pH 11.0 and 2% NaCl addition on process of manufacture of pork leg surimi would be recommended.
