SUMMARY– The influence of relative humidity on the formation of metmyoglobin at 0‐2°C, was studied. Decreased water content of semitendinosus muscle led to increased metmyoglobin formation, but only at degrees of dehydration that led to marked discoloration due to other causes e.g., heme concentration. Metmyoglobin formation was very dependent on the anatomical location of The muscle (P <0.001). The susceptibility to metmyoglobin formation for the four muscles studied was biceps femoris > semimembranosus > longissimus dorsi = semitendinosus.
