What is the possibility that the Cure #1 DIDN'T get added. That would give a Pink exterior from a Smoke Ring and a Gray center, this would make more sense if all the ropes are the same way. Just a wild guess..JJ
@indaswamp Both you and @PolishDeli are correct...
What is carbon monoxide and why is it used in foods?
Carbon monoxide (chemical formula CO) is a colorless, odorless, flammable and highly toxic gas. It is a major product of the incomplete combustion of carbon and carbon-containing compounds.
Carbon monoxide binds hemoglobin in much the same way that oxygen does, only 200x stronger. In fact
CO will displace oxygen from hemoglobin (or
myoglobin) because it has such great affinity for hemoglobin. It is a known fact that carbon monoxide is used in processed meats and fish to keep the color of blood red for long periods of time. This keeps the meat looking fresh red for a long time.
Note: Oxygen and Carbon monoxide are not the only molecules to bind hemoglobin (or
myoglobin).
Nitric Oxide also does the same thing. Nitric Oxide can be formed from Nitrates. Nitrites are the reason cured meat is pink or red. Nitrites turn into Nitric Oxide, which reacts with the oxygen-binding proteins in the meat. Without the nitrites the cured meat would turn brown quickly.
Why are food companies using carbon monoxide in fish and meat?
