What keeps ground beef red?
Ground beef’s bright red color comes from a pigment, myoglobin, which becomes red when exposed to oxygen (turning it into oxymyoglobin). The plastic wrap covering the ground beef you see in the grocery store is permeable, allowing some oxygen to seep through and keep the meat on the exterior red.
What do butchers put on meat to keep it red?
Nitrites keep meat red by bonding to the myoglobin and acting as a substitute for the oxygen. Oxygen and sodium nitrate both turn myoglobin red, but nitrate attaches with a more stable bond and so the color lasts longer.
Do butchers add red dye to meat?
Brown meat can also be ‘flushed’ with gas to make it look red and “fresh” again, while butchers in Sydney were busted in 2010 for illegally using sulphur dioxide (a major ingredient in many batteries and responsible for serious allergic reactions in people) to disguise old or rotting meat.
Is ground beef bad if it’s not red?
Check the color The interior of raw ground meat may be greyish brown due to a lack of exposure to oxygen. This doesn’t indicate spoilage. Nevertheless, you should throw away ground beef if it has turned either brown or gray on the outside, as this indicates that it’s beginning to rot.
Why is my ground beef dark red?
As the USDA explains, “Oxygen from the air reacts with meat pigments to form a bright red color which is usually seen on the surface of meat purchased in the supermarket.” That pigment is called oxymyoglobin, a substance found in all warm-blooded animals, and it explains why the outside of that pile of meaty goodness …
Why is my beef dark red?
When exposed to air, myoglobin forms the pigment, oxymyoglobin, which gives meat a pleasingly cherry-red color. The use of a plastic wrap that allows oxygen to pass through it helps ensure that the cut meats will retain this bright red color. This color change alone does not mean the product is spoiled.

What color is meat naturally?
When meat is fresh and protected from contact with air (such as in vacuum packages), it has the purple-red color that comes from myoglobin, one of the two key pigments responsible for the color of meat. When exposed to air, myoglobin forms the pigment, oxymyoglobin, which gives meat a pleasingly cherry-red color.
Is Partridge red or white meat?
Quail and partridges are white meat and, like chicken, must be thoroughly cooked but not dried. Ducks, pigeons or squabs, grouse (prairie chicken), snipe, and woodcock are dark meat and are preferred by the epicure cooked rare and served very hot.
Is it OK to eat beef that has turned brown?
After beef has been refrigerated for about five days, it may turn brown. This darkening is due to oxidation, the chemical changes in myoglobin due to the oxygen content. Beef that has turned brown during extended storage may be spoiled, have an off-odor, and be tacky to the touch and should not be used.
Is GREY Steak safe to eat?
Looking at Raw Meat Examine this meat carefully before cooking. After extended storage, the gray-brown color is a sign of spoilage if the meat is also sticky to the touch, smells bad and develops a clear goo on the meat’s surface. Do not taste or cook this meat; instead, throw it away.
What does it mean when meat turns dark?
So why does meat turn brown? Both myoglobin and oxymyoglobin have the ability to lose their oxidation which results in a brown color called metmyoglobin. This essentially means that meat can turn from a bright red color (which many associate with fresh) to a brown color from a lack of oxygen.
