Abstract
In order to explore the relationships among MRA, OCR and color stability of different bovine muscles, MRA, MMb and OCR were determined in longissimus lumborum (LL) , semitendinosus (ST) and psoas major (PM) displayed for 5 days at 4℃ in the dark.The result indicated that color stability of LL was best, PM worst and ST in the middle. Moreover, muscles of higher levels of MRA or lower OCR had higher color stability.
