RELATIONSHIP BETWEEN MUSCLE TYPE AND MYOGLOBIN OXIDATION OF HANWOO MUSCLE DURING COLD STORAGE

摘要

IntroductionThe myoglobin oxidation in muscle depends on the muscle type and species. Trout and Gutzk (1995) reported that there are differences in myoglobin oxidate rate of different bovine muscles indicate that different muscle types are also important factors to affect the oxidation rate of myoglobin. Differences on Mb oxidation rate can be due to differences in concentration of endogenous antioxidaiton and pre-oxidation. Renerre (1990) reported that at 192 h postmortem, M. longissimus dorsi are the most stable, M. semimembranosus being of intermediate stability whilst M. psoas major are of least stability. There are other possible reasons for the different myoglobin oxidizes rate of enzyme activity (NADH) in postmortem muscles. Consequently, the characteristic by diffement muscle type was different in color stability.
