Put a pound of ground beef in a self-defrost freezer and pretty soon it'll be brown around the edges.

Put it in the fridge and sooner or later you'll see a similar brown. I don't think my fridge crosses the freezing point, not since we lost an expensive bottle of insulin to that very thing and messed with the thermostat a tad. Is the blood simply draining out of the tissue? What's going on there?

What is called freezer burn is simplya very advanced dessication. The meat dried out in the dry cold environment. It isnt bad for you , but its not very tasty. Freezer burn is easily prevented by wrapping meat in plastic wrap before freezing, making sure to leave no airspace.

Best method is to use a vaccuum sealer. I routinely use meat a couple years old with no problems.

Well, freezer burn also involves bursting the cell walls, which I'm guessing isn't going on in my fridge. I had no idea oxygenation could turn muscle tissue brown -- after all, oxygenated blood is red -- but hey, learn something new every day. :-)

Yeah, now that I have a chest freezer, it might be worth looking into vacuum sealers. So far I haven't had anything long enough for freezer bern!

Ah, but what color does the arterial spray on the ceiling turn after a few hours? Brown.

Well, that's true. I guess I don't know how long stuff like clotting agents last after a chunk of muscle goes through a grinder. I clearly don't read the right kind of novels.
