Abstract
The ratio of monounsaturated fatty acids to the total fatty acids (MUFA ratio) has attracted attention due to the positive correlation with the flavor of the beef meat. However, the fluctuation of the MUFA ratio within muscles was not surveyed as most studies investigated using only a portion of the muscle. In this study, the fluctuation of the MUFA ratio within skeletal muscles and the relationships with the rib eye between the 6-7th rib were investigated using 6 muscle parts (M. semimembranosus, M. quadriceps and M. tensor fasciae latae, M. supraspinatus, M. major psoas, M. gluteus medius and M. biceps femoris, M. longissimus) of 5 Japanese Black cattle cloned from somatic cells. These muscle parts were sliced at 2 cm intervals from the cranial side to the caudal side. The cranial part from the 6-7th ribs of M. longissimus was categorized as chuck eye and the others as loin. Samples of adipose tissue were taken from the surface of each slice, and the fatty acid composition was analyzed using gas chromatography. The variation of the MUFA ratio was affected by the muscles and derived animals. The interaction between the muscles and derived animals for the MUFA ratio was significant (P < 0.01), suggesting that the muscle which tends to have a high MUFA ratio differed between the derived animals. The correlation coefficients between MUFA ratios of the rib eye at the 6-7th rib and each muscle were significantly high (r = 0.92∼0.99, P < 0.05). Furthermore, relationships among muscles were also strong(r = 0.98∼0.99, P < 0.01). These results indicated that the MUFA ratio representing the whole carcass could be obtained by measuring at the 6-7th rib eye.
