Comparison of Assays for Metmyoglobin Reducing Ability in Beef Inside and Outside Semimembranosus Muscle

Abstract: The relationships of 6 assays for metmyoglobin (Metmb) reducing ability to color stability and the chemical differences between the inside (ISM) and outside (OSM) beef semimembranosus (SM) muscle after 5 or 14 d storage were investigated. The ISM had less (p < 0.05) color stability than the OSM regardless of time post mortem, and both muscle portions were more color-stable when stored for 5 d rather than 14 d. Among the assays, aerobic reducing ability correlated best with visual color scores (r = -0.58) and M… Show more

“…In agreement, the Mb concentration was not found to be indicative of color stability in blesbok muscles as well (Neethling et al, 2016). Similarly, other studies have also reported that the relationship between Mb concentration and color stability in beef muscles is inconclusive (Sammel et al, 2002;McKenna et al, 2005;Canto et al, 2015).…”

“…Nevertheless, evidence has shown that both reducing activity and OC have an influence on the color stability of muscles (Madhavi and Carpenter, 1993). In contrast, other researchers have suggested that low OC negatively affects color stability as mitochondrial respiration is required to replenish the NADH required for MRA (Sammel et al, 2002).…”

“…The methodology described by Sammel et al (2002) was used for evaluating MRA. Samples from the oxygen-exposed surface (approximately 2.5 × 2.5 × 2.5 cm cubes with no visible fat or connective tissue) were submerged in 0.3% solution of sodium nitrite (SigmaAldrich Co., St. Louis, MO) for 20 min at room temperature to facilitate metmyoglobin formation.…”
