Abstract

This study was investigate correlation of moisture content, relative humidity, pH, color difference, myoglobin(Myo), oxymyoglobin(Oxy) and metmyoglobin(Met). The moisture content, relative humidity of loin and shank were not changed uniformly during storage, the pH was raised according to storage period. The L value was raised at the closing stage of the storage period, the surface of the b value was higher than interior. Between Myo and Met were positive correlation in common with loin and shank. The surface and interior of loin were negative correlation between Oxy and Met, the surface and interior shank were positive correlation between Myo and L value and were negative correlation between Myo and Oxy. The moisture content, relative humidity, pH and color was not correlation uniformly.
