Is carbon monoxide used in meat packaging?

Red meat products are somewhat like sliced apples. But by eliminating the oxygen from the package and adding minute amounts of carbon monoxide along with other protective gases to the headspace of the red meat packages, products like ground beef can maintain their appealing red color throughout their shelf life.

Why is carbon monoxide used in meat packaging?

The use of CO in fresh meat packaging gives promising results due to its positive effects on overall meat quality, enhancement red color, reduced lipid oxidation and microorganism growth inhibitions, which result in shelf-life prolongation during wider distribution of case-ready products.

Is carbon monoxide a Food preservative?

The FDA has so far allowed carbon monoxide packaging for beef, pork and raw tuna when used as an ingredient in tasteless smoke, used as a preservative. Instead, the FDA allows it under regulations for substances that are “generally recognized as safe,” based on evidence submitted by proponents.

What are four other factors that can affect the color of meat?

The color intensity of meat is determined by such antemortem factors as species, stress, sex and age of animal, postmortem pH rate of decline and ultimate pH of the meat. The color intensity differences between species are primarily caused by differing concentrations of myoglobin.

Why is tilapia pink?

It’s hard to tell, but the general giveaway is flesh that’s usually bright. Fresh, untreated tilapia tends to have a pink vein (the bloodline) running down the center of the filet. Carbon monoxide treated tilapia has a red and almost orange vein. Check out the color of recently filleted tilapia.
