This darkening is caused by oxidation, which is a chemical alteration in myoglobin as a result of the presence of oxygen in the blood. This is a typical alteration that occurs during the preservation of food in the refrigerator.

Why does red meat turn brown when vacuum sealed?
- What Causes Red Meat to Turn Brown When Vacuum Sealed.
- As beef ages, it develops a brown color due to oxidation.

Metmyoglobin is produced as a result of this process.In older meat, the pigment metmyoglobin is responsible for the distinctive brown coloring that develops as it matures.
What causes brown spots on raw meat?
Interestingly enough, myoglobin is the same protein that gives raw chicken and pork a reddish tint, albeit the hue is less noticeable in those instances. Eventually, after a number of days, the myoglobin will oxidize, which means it will go through chemical changes that will cause brown spots to form on the beef.
Is it safe to eat steak with brown patches on it?
As a result of oxidation, brown spots may occur on the surface of meat from time to time. If the steak does not smell unpleasant, does not feel sticky or slimy, and does not exhibit any other evident indicators of deterioration, it should be safe to consume. What Causes Steak to Turn Red?
