Is red meat red because of blood?

What is the liquid coming out of steak? Even the rarest and reddest of steaks is actually bloodless. Instead, what you're looking at is a combination of water, which makes up about 75 per cent of meat, and a protein found in muscle tissue called myoglobin.

What makes meat red vs white?

White and red meat differ in their amount of myoglobin, the protein responsible for a meat's color. Red meat has more myoglobin than white meat, and a higher myoglobin content generates a darker meat color.

What do butchers put on meat to keep it red?

Nitrites keep meat red by bonding to the myoglobin and acting as a substitute for the oxygen. Oxygen and sodium nitrate both turn myoglobin red, but nitrate attaches with a more stable bond and so the color lasts longer.

Why is chicken meat white?

What color is meat naturally?

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.

Insider further elaborates that gray steak is actually a fairly common occurrence, and it can be cooked and consumed safely, provided that it isn't slimy or giving off an unpleasant odor.

Why is my raw steak grey?
