Fresh beef is originally purplish in color, and exposure to oxygen turns it into the bright red we commonly see in stores. Over time, continued oxidation causes the meat to turn brown. While this discoloration might look unappealing, it doesn’t mean the meat is unsafe.
However, brown meat is usually older. If you choose to buy it, it’s best to cook it right away since it has likely been sitting out for a few days.
Many people also wonder why rare steak appears to “bleed.” In reality, meat is about 70% water. When this water mixes with a protein called myoglobin and other natural pigments, it creates a red liquid that resembles diluted blood.
This liquid is not blood. It’s simply a combination of water and myoglobin released from the meat.
Recently, a steak enthusiast shared this fact online, surprising many people. Some admitted they had always believed the red liquid was blood, while others found the explanation fascinating.
So next time you cut into a juicy steak, you can be confident that the red liquid isn’t blood—it’s just a natural part of the meat.
