Nope! It is completely standard practice. Myoglobin is the protein that is responsible for the red coloring that is found on the exterior of the ground beef, and it even has a name for itself: myoglobin. When meat, or even poultry, is packaged, the meat on the exterior is subjected to a greater concentration of oxygen than the meat on the inside.

Why is ground beef red inside but Brown outside?
Because the outside of the ground beef is exposed to air once again during the packaging process, the meat acquires its characteristic bright red hue. Because oxygen is only able to permeate the flesh to a certain depth, the center of the cut will be browned.
What color is fresh ground beef?
The Department of Agriculture of the United States of America describes the color of freshly ground beef as having a purple hue. Oxygen’s reaction with the pigments in the meat is what gives it its characteristic brilliant red color after it’s been purchased from a grocery shop.
Why is ground beef purple in color?
Because there is not enough oxygen to cause the meat to ″bloom,″ the inside of the cut is a dark purple color (term used in industry to signify the conversion from the purple state to the red state in the presence of oxygen). During the process of grinding the beef into ground beef, a small amount of air is mixed in with the meat.
What gives meat its red color?
Oxygen from the air mixes with the pigments in meat to produce a vibrant red hue, which can typically be observed on the surface of meat that has been purchased from a grocery store. Oxymyoglobin, a chemical that is present in all animals with a warm blood temperature, is the pigment that gives meat its characteristic red color.
Is beef safe to eat if it turns GREY?
If you open a package of ground beef and find that the flesh inside looks gray, this is most likely because the meat has not been exposed to oxygen for a prolonged period of time. In such a scenario, the meat can still be consumed without risk, providing that it does not exhibit any other symptoms of spoiling (read more on that below).
Why is my ground beef GREY in the middle?
The pigment responsible for the red color of meat is oxymyoglobin, a protein present in all warm-blooded mammals. Fresh sliced meat is violet in hue. The inside of the meat may be grayish brown owing to lack of oxygen; however, if all the meat in the package has become gray or brown, it may be beginning to rot.
What does it mean when raw beef turns GREY?
The chemical component that makes up myoglobin contains iron, which, after being exposed to air for a few days, will begin to oxidize. This results in the production of metmyoglobin, which is what causes the flesh to turn a color similar to that of your grandfather.
What does it mean if all of the meat in the package turns gray or brown and has a funny smell?
When raw beef begins to show signs of browning or graying (even if it’s just a tiny piece of the package), it’s necessary to complete the smell and touch tests as soon as possible. The graying of beef is a normal process that happens as it continues to oxidize, but you should chuck it out if there is any residue that is sticky or if it smells rancid.
How do I know my ground beef is bad?
To tell whether your ground beef if rotten, utilize your senses. Touch the ground meat. If it’s slimy, that’s not typical. Smell and visually examine at your ground beef, and if it’s brown or an odd odor, they might be symptoms that your ground beef is bad.
What does spoiled ground beef look like?
How the ground beef appeared visually. You want the color of your ground beef to be a bright crimson.

It’s usual for pre-packaged ground beef to have a brown spot or two in the centre of the patty sometimes.
What happens when ground beef turns brown in the fridge?
- This darkening is caused by oxidation, which is the process by which myoglobin undergoes chemical changes as a result of the presence of oxygen.
- This is a natural occurrence that occurs throughout the refrigeration process.
- The usage of beef that has gone brown while being stored for a prolonged period of time is not recommended since it may be ruined, have an unpleasant odor, and feel sticky to the touch.
Why did my hamburger turn brown in the fridge?
While being stored in the refrigerator, the oxygen in the meat causes the ground beef to turn brown. Consuming ground beef that has become brown is not in any way dangerous to do so. A simple change in color does not necessarily indicate that the meat has gone bad. Before making a purchase, make sure to check the product’s expiration date and select a vendor you can trust.
Why is red meat grey?
- The United States Department of Agriculture (USDA) describes particularly fresh beef as having a reddish hue.
- That’s right—the brilliant red hue, which most of us associate with beef, is not always a sign of how recently the meat was prepared.
- The color of the flesh changes from white to red as soon as the exposed surface is exposed to oxygen.
- When the flesh is not exposed to air, it takes on a color that is between between gray and brown.
How can you tell if frozen beef is still good?
- The color of the meat is the single most reliable indicator of whether or not it should be consumed.
- If the middle of the meat develops a grey hue, there may be anything wrong with the cooking process.
- This should be thrown away as it poses a risk of contamination to other frozen meals.
- Despite this, the exterior of the meat should still be red if it is to be consumed safely if it is still in its raw state.
How can you tell if cooked beef is bad?
After it’s been cooked, how can I tell if the steak is still good? After being grilled or seared, if your steak develops mold, changes in color, or unusual odors, these are all indications that the meat has gone bad.
How can you tell if steak is spoiled?
- When the steak has gone rotten, it has a slimy texture.
- It has a slimy layer on the surface, which is noticeable when you touch it.
- The slime has a slick and tacky texture, both of which are indicators of a bad steak that is just a few days away from molding.
- The presence of mold is a warning sign that the fresh meat has become contaminated with germs and is no longer suitable for consumption.
Is ground beef good after 4 days in fridge?
It is recommended to consume any remaining ground beef within four days, although it can be safely stored in the refrigerator for one to two days. When stored properly in the freezer, ground beef has a shelf life of up to four months. When cooking ground beef, the internal temperature must reach a minimum of 160 degrees Fahrenheit (71 degrees Celsius) as measured using a food thermometer.
How long is ground beef good in the fridge?
- According to the guidelines provided by the United States Department of Agriculture (USDA), a package of ground beef can be stored in the refrigerator for up to two days from the day it was purchased.
- After the first day, the ground beef should be cooked or frozen as soon as possible.
- Because it can be stored in the freezer for a considerable amount of time without going bad, ground beef is an excellent option for long-term solutions.
How can you tell if thawed ground beef is bad?
When it is still warm from the butcher, the interior of ground beef should have a brownish hue, while the exterior should have a vivid red color. If the surface has turned entirely dark or gray, or if mold has grown on it, then it has been spoiled and need to be thrown away.
