Physicochemical properties of of Korean native pigs.

BACKGROUND

The meat quality of Korean native pigs (KNP) and crossbred pigs (LYD; Landrace × Yorkshire × Duroc) was examined to generate data useful for selecting native pigs for improved pork production.

METHODS

Fifty Korean native pigs (KNP) and 50 crossbred pigs (LYD) were tested. Loin samples () of the two breeds were analyzed to determine meat quality and sensory properties.

RESULT

KNP had a higher moisture content than LYD ( < 0.05); however, it had significantly lower crude fat and ash content than that of LYD ( < 0.001). KNP had significantly higher shear force than LYD ( < 0.01). KNP also showed significantly higher cooking loss than LYD ( < 0.05). KNP had a lower L value than LYD ( < 0.05); however, it had a markedly higher a and b value than LYD ( < 0.001). KNP showed significantly higher linoleic acid, linolenic acid, and arachidonic acid content than LYD ( < 0.05). Although KNP had significantly better flavor and overall palatability than LYD, it was less tender than LYD ( < 0.01).

CONCLUSION

KNP had a markedly higher a value than LYD. KNP had significantly higher shear force than LYD. The total unsaturated fatty acid content was higher in KNP than in LYD.
