Why does meat dry out in the freezer after a while?

Well that’s a tricky one, humans! It turns out that you don’t actually freeze the meat, you only cool it down.  Meat still contains proteins and enzymes, and the proteins and enzymes aren’t affected by temperature, but they are affected by “crystallization” – when the cold liquid water in the meat becomes a solid.  It’s this crystallization that causes the meat to dry out.  On the other hand, if you freeze the meat, you freeze all the liquid, which prevents the crystallization from taking place, and the meat never dries out.  If you want to freeze meat without it drying out, you can put it in the fridge before you freeze it.

The two most likely reasons are that the meat has lost its moisture, and that the surface of the meat has grown dry and cracked.  This happens more in wet climates, where the moisture gets wiped out of the meat.
