Quality Characteristics of Korean Native Pigs Slaughtered at Commercial Market Weight

Ninety KNP were divided into three group by differential market weight(20 of each group): Live weight of Group 1(G 1), Group 2(G 2) and Group 3(G 3) were 50-59kg, 60-69kg, 70-80kg, respectively. Values of pH and shear force showed an increase, while cooking loss showed decreased with increased weight. In color analysis, a^* value in meat and b^* value in backfat of KNP showed higher as slaughter weight increased. Slaughter weight did not significantly affect the fatty acid composition of subcutaneous fat of KNP. With the exception of oleic acid in intermuscular fat, there were no significant weight-dependent differences in the fatty acid profiles.
