Why is my raw steak GREY?
Keeping this in view, is it OK to eat steak that has turned GREY?
If the meat is not exposed to oxygen, it changes to a gray-brown hue. But that does not mean it is spoiled. Ground beef that has been frozen may also turn gray, but it is still safe to eat if stored properly.
Beside above, what color should raw steak be? As discussed earlier, fresh cut meat is purplish in color. Oxygen from the air reacts with meat pigments to form a bright red color which is usually seen on the surface of ground beef purchased in the supermarket. The interior of the meat may be grayish-brown due to the lack of oxygen penetrating below the surface.

Freshly cut meat is pink-red due to the reaction of myoglobin with oxygen. It turns gray as myoglobin changes to metmyoglobin. Packaging (and exposure to carbon monoxide) enhances and prolongs the red color.

The presence of oxygen, however, eventually turns beef grayish-brown. Myoglobin's chemical compound contains iron, which, after a few days of oxygen exposure, will oxidize. This creates metmyoglobin, which is responsible for the meat turning grayer than your grandpa.
