Metmyoglobin - Wikipedia, the free encyclopedia
Metmyoglobin is the oxidised form of the oxygen-carrying protein myoglobin. Metmyoglobin is the cause of the characteristic brown colouration of meat that occurs as it ages. In living muscle, the con...

The cooked pigment is denatured metmyoglobin. It is brown and is easily recognized in cooked meat products. Certain meat conditions can result in protection of the myoglobin. The ultimate pH of the muscle is one of these conditions.

In this work, the ability of some ubiquitous dietary antioxidants representative of the main antioxidant classes (alpha-tocopherol, the flavonol quercetin, beta-carotene) to inhibit the metmyoglobin-induced peroxidation of linoleic acid is investigated by UV-visible spectroscopy and HPLC in mildly acidic emulsions.
