Abstract

This study was conducted to investigate the influence of dietary oriental medicine refuse(OMR) and mugwort powder on physico-chemical characteristics of Korean Native Pork(KNP). KNP were randomly assigned to one of the three dietary treatments : 1) control (commercial feed) 2) T1 (commercial fed supplemented with 10% OMR powder) 3) T2 (commercial feed with 10% mugwort powder). 15 heads(♂) were feed one of the experimental diets for 5 months and slaughtered. In the proximate composition, moisture content showed slightly high in the T1, however, fat content were tended to be high in the control. The heating loss, shear value, WHC (water holding capacity) were not significantly between control and the treatments group. The T1 showed the lowest pH among treatments (P<0.05). In sensory evaluation, juiciness and tenderness of T1 and T2 were higher compared with that of control. Hunter a* did not show any difference among the treatments group. But Hunter L*, b* in treatment group(T1, T2) were higher than that of the control. Oleic acid, linoleic acid and unsaturated fatty acid contents of T1 and T2 were higher than the control. The total amino acid of the control, T1 and T2 were 18.290, 18.177 and 18.942mg%, respectively.
