In this method, chemically produced deoxymyoglobin interacts with CORMs in buffered solution to form carboxymyoglobin
. Deoxymyoglobin/carboxymyoglobin transformation can easily be detected with a UVVis Spectrophotometer.
Due to the formation of carboxymyoglobin
between carbon monoxide (CO) and myoglobin , CO is very effective in maintaining red color for fresh meats [11-16].

after photodissociation of carbon monoxide," Journal of the American Chemical Society, vol.
Its negative effects are union with Hb to form carboxyhemoglobin (COHb), which causes blockage in the transport of oxygen (2) and also its union with proteins, mostly myoglobin, thereby forming carboxymyoglobin
which is found in the heart and musculoskeletal system.
Meat color is attributed to carboxymyoglobin
, deoxymyoglobin, oxymyoglobin and metmyoglobin.
poses a serious threat to a CO victim because the myocardium can be severely deprived of oxygenation.
Carbon monoxide replaces air to extend the shelf life of meat, out it also apparently reacts with the meat pigment myoglobin to create carboxymyoglobin
, a red pigment that masks some of the natural aging and spoilage of meats, according to a petition filed late last year by Kalsec Inc., Kalamazoo, Mich.
