Beef Turned Brown in Freezer Reddit

  • #1
I call up reading on ATOT that it'due south better once information technology turns brown. Why does this happen though? This site says that beefiness is naturally nighttime and turns bright ruby-red when exposed to oxygen.. But I've left beef in the fridge for a few days, and it's turned from reddish TO brown. What'due south the deal??

Ah I found another site.. http://ask.metafilter.com/mefi/21292
When freshly slaughtered meat is cut into steaks, the muscle tissue comes into contact with oxygen in the air. The myoglobin in the meat binds this oxygen, forming oxymyoglobin and giving the meat a carmine color. However, if fresh meat sits for a period of time, more often than not over the course of several days, the construction of the myoglobin changes. The fe molecule in the center is oxidized from its ferrous to ferric form and a different complex is formed called metmyoglobin. This compound turns the raw meat a dark-brown color. The meat is usually still prophylactic to eat when cooked, but the brown, unappealing color turns off about consumers. To avoid having your fresh meat turn brownish, use it as soon as possible later purchasing it.

Its the oxygen or something in the air. I work at a eatery and the peak pieces of meat like beefiness tenderloin, lamb and any other kind of meat in the stack will offset turning brown while the pieces of meat under information technology will stay their natural night crimson color.

they accept a lower fridge setting than nearly fridges at domicile. their's run basically below freezing just similar freezers, but in that location'due south an air-room temperature buffer and so it acts like a supercool refrigerator

geez...yous'll be fine.

If it says sell by you tin put it in the refrigerator until then and a few days after and you will exist fine. This is assuming the sell by date is only a day or 2 afterward the purchase date. If you know yous wont' utilise information technology for a while - freeze it. Otherwise a little browning is normal and will not harm you.
