In general, it is fully understood that cured color formation resulted from the conversion of MbFe2+ and/or MbFe2+O2 into nitrosomyoglobin (MbFe2+NO), resulting in ligand binding of Mb and nitric oxide (NO) that was generated from nitrite (Eyiler & Oztan, 2011). In this progress, MbFe2+ and/or MbFe2+O2 was oxidized into MbFe3+ by oxygen or nitrous acid derived from nitrite.
