When it comes to enjoying a perfectly cooked steak, the color of the meat is often a key factor in determining its quality and freshness. Many of us have been taught that brown steak is a sign of spoilage or poor quality, leading to the question: can you still eat steak if it turns brown? In this article, we will delve into the science behind steak color and safety, exploring what causes steak to turn brown, how to determine if a brown steak is still safe to eat, and the importance of proper storage and handling techniques.
Understanding Steak Color
The color of steak is primarily determined by the presence of a protein called myoglobin. Myoglobin is responsible for storing oxygen in the muscle cells of the steak, giving it a red or pink color. When steak is exposed to oxygen, the myoglobin reacts with the oxygen to form a compound called oxymyoglobin, which is responsible for the bright red color of fresh steak. However, when steak is cut or sliced, the myoglobin is exposed to oxygen, causing it to react and form metmyoglobin, a brown-colored compound.
The Role of Oxidation in Steak Color
Oxidation is a chemical reaction that occurs when the myoglobin in the steak reacts with oxygen. This reaction can cause the steak to turn brown, but it does not necessarily mean the steak is spoiled or unsafe to eat. In fact, some types of steak, such as dry-aged steak, are intentionally allowed to oxidize, resulting in a more complex and intense flavor profile. However, excessive oxidation can lead to the formation of off-flavors and textures, making the steak less desirable.
Factors that Influence Steak Color
Several factors can influence the color of steak, including:
The type and quality of the steak
The level of oxygen exposure
The storage and handling conditions
The age of the steak
For example, grass-fed steak tends to have a more intense red color than grain-fed steak, due to the higher levels of myoglobin present in the muscle cells. Similarly, steak that is stored in a vacuum-sealed package will retain its red color longer than steak that is stored in a non-vacuum package, due to the reduced exposure to oxygen.
Determining if a Brown Steak is Still Safe to Eat
While a brown steak may not be as visually appealing as a red steak, it can still be safe to eat if it has been stored and handled properly. The key to determining if a brown steak is still safe to eat is to check for other signs of spoilage, such as an off smell, slimy texture, or mold growth. If the steak has an unpleasant odor or texture, it is best to err on the side of caution and discard it.
Checking for Spoilage
To check for spoilage, follow these steps:
Check the steak for any visible signs of mold or slime
Smell the steak for any off or unpleasant odors
Check the texture of the steak for any signs of softness or sliminess
Check the packaging for any signs of damage or tampering
If the steak passes these checks, it is likely still safe to eat. However, it is always better to err on the side of caution when it comes to food safety, and if in doubt, it is best to discard the steak.
Proper Storage and Handling Techniques
Proper storage and handling techniques are crucial in maintaining the quality and safety of steak. Steak should be stored in a cool, dry place, such as a refrigerator or freezer, and should be handled gently to avoid damaging the meat. It is also important to label and date the steak, so that you can keep track of how long it has been stored.

What causes steak to turn brown, and is it still safe to eat?
The color change in steak is primarily due to a chemical reaction involving myoglobin, a protein found in muscle tissue. When myoglobin is exposed to oxygen, it forms a compound called oxymyoglobin, which gives the meat its characteristic red color. However, as the meat ages or is exposed to heat, light, or oxygen for an extended period, the oxymyoglobin can break down, leading to the formation of metmyoglobin, which causes the meat to turn brown. This reaction can occur even if the steak is stored properly in the refrigerator.
It is essential to note that the color change alone does not necessarily indicate spoilage or foodborne illness. Other factors, such as the presence of off-odors, slimy texture, or mold growth, should be considered when determining the safety of the steak. If the steak has turned brown but still smells fresh and has a firm texture, it may still be safe to eat. However, it is crucial to use your best judgment and err on the side of caution.
