Nosotros have all done it… bought a package of ground beef at the grocery store. It looks nice and cerise in the package. You take information technology out of the package to make hamburger patties or to brown it in a skillet and… it'south brown on the inside, even though it is a beautiful red on the outside.

What's going on? Is dark-brown footing beef safe to eat? Should you swallow brown ground beefiness? Is your butcher trying to flim-flam you?

The brusk reply is – Yeah, information technology is safe to eat. YES, you should still consume it. NO, your butcher is not trying to trick you lot.

It'south all about science.

Myoglobin

Beef is muscle. And musculus has a pigment called myoglobin. This is very like to hemoglobin, the pigment in your blood that makes your claret red. Both myoglobin and hemoglobin contain iron (which becomes of import in a minute).

If you remember dorsum to class schoolhouse science, you might retrieve near hemoglobin. You breathe air in through your lungs. Your blood travels through your lungs, and picks up oxygen with hemoglobin. The hemoglobin turns bright red, which makes your blood turn bright red. As your blood travels through the rest of your body, the oxygen gets delivered to other tissues and taken off the hemoglobin. As the oxygen comes off the hemoglobin, it turns a dark reddish or purple color. So the hemoglobin gets back into your lungs, picks up more than oxygen, and the process starts all over again.

The same kind of thing happens in muscle with myoglobin. Bank check out this keen explanation near the colour of steaks from Mom at the Meat Counter. In meat, myoglobin starts out as a dark purple colour. When it is exposed to oxygen (either from hemoglobin in the blood or from the air), it turns red.

Enzymes in the meat utilize the oxygen. In order to apply the oxygen, these enzymes accept abroad some of the electrons from the atomic number 26 in the myoglobin, which turns the myoglobin dark-brown.

Other enzymes in the meat give those electrons dorsum, which turns the myoglobin back to imperial.

Then the whole bicycle can start once again.

In ground beef, things are a picayune bit dissimilar than in a steak or roast. Because and then much of the meat is exposed to air when ground beef is made, the myoglobin gets saturated with oxygen. The enzymes that use the oxygen still work, turning the myoglobin brown. Just the enzymes that make myoglobin purple again are overwhelmed, and tin can't do their job to make the myoglobin purple again. Then the myoglobin (and the meat) stays brown.

When ground beef is packaged, the outside of the meat is exposed to air again, so it turns that pretty scarlet color. The air tin can only penetrate so far through the meat, so the inside stays brownish. When you get it home and break it open, the chocolate-brown function of the meat should offset to turn carmine again when it is exposed to the air! Bully, right?
