This study was carried out to compare of yield, physico-chemical and sensory characteristics for chicken surimi manufactured by alkaline (pH 11) adjustment with different raw materials. Four experimental groups were surimi with chicken breast (T1) and chicken leg (T2) by spent hen, SF-MDCM (T3) and JY-MDCM (T4). Yield was higher in order of T1>T2>T3>T4 (p<0.05). The yield, physico-chemical and sensory characteristics of T1 were significantly higher than those of other treatments. Especially, and W value, shear force, textural properties, folding test, breaking force, gel strength, breaking , flavor, color and overall acceptability were higher in T1 but ar value, cooking loss, collagen and myoglobin content of T1 were lower than those of other treatments (p<0.05). Deformation, aroma, juiciness, tenderness were higher but met-myoglobin and yield of T4 were lower than those of T2 and T3 (p<0.05). Crude fat cooking loss and met-myoglobin content were higher in T2 but value, brittleness, hardness, gumminess, chewiness, folding test, breaking and aroma of T2 were lower than those of other treatments (p<0.05). pH, collagen and moisture content and br value were higher but crude protein, folding test, and W value, cohesiveness, tenderness of T3 were lower than those of other treatmene (p<0.05). Correlation coefficients (r>0.8) between folding test and other items was positive in crude protein value, shear force and cohesiveness but negative in moisture content (p<0.05).
