Nosotros take all done it… bought a package of ground beef at the grocery shop. It looks nice and red in the package. You take it out of the package to brand hamburger patties or to brown it in a skillet and… it's brown on the inside, even though information technology is a cute red on the outside.
What'due south going on? Is chocolate-brown ground beef safe to eat? Should yous eat chocolate-brown basis beef? Is your butcher trying to trick you lot?
The brusque respond is – Aye, it is rubber to eat. Yes, you lot should however eat it. NO, your butcher is not trying to flim-flam you.
It's all well-nigh scientific discipline.
Myoglobin
Beef is muscle. And musculus has a pigment called myoglobin. This is very similar to hemoglobin, the pigment in your blood that makes your blood red. Both myoglobin and hemoglobin contain iron (which becomes important in a minute).
If you remember back to class school science, you might think about hemoglobin. You breathe air in through your lungs. Your blood travels through your lungs, and picks upwards oxygen with hemoglobin. The hemoglobin turns bright cherry-red, which makes your blood turn brilliant red. Every bit your claret travels through the balance of your trunk, the oxygen gets delivered to other tissues and taken off the hemoglobin. As the oxygen comes off the hemoglobin, it turns a dark cherry or purple color. And so the hemoglobin gets back into your lungs, picks upward more oxygen, and the procedure starts all over again.
The aforementioned kind of affair happens in muscle with myoglobin. Check out this great explanation about the color of steaks from Mom at the Meat Counter. In meat, myoglobin starts out as a night imperial color. When it is exposed to oxygen (either from hemoglobin in the blood or from the air), information technology turns red.
Enzymes in the meat utilise the oxygen. In gild to use the oxygen, these enzymes take away some of the electrons from the fe in the myoglobin, which turns the myoglobin brown.
Other enzymes in the meat give those electrons back, which turns the myoglobin dorsum to purple.
Then the whole cycle can start again.
In ground beefiness, things are a footling chip different than in a steak or roast. Because so much of the meat is exposed to air when ground beefiness is made, the myoglobin gets saturated with oxygen. The enzymes that apply the oxygen yet piece of work, turning the myoglobin brown. Simply the enzymes that make myoglobin purple again are overwhelmed, and can't do their job to brand the myoglobin purple again. And then the myoglobin (and the meat) stays brown.
When ground beef is packaged, the exterior of the meat is exposed to air again, so information technology turns that pretty red colour. The air tin can just penetrate so far through the meat, then the within stays dark-brown. When yous go it home and break it open, the brown part of the meat should start to turn cerise again when it is exposed to the air! Keen, correct?
