What stops freezerburn?

Freezer burn is caused by air or moisture around foods when they are placed in the freezer. Once it happens, the taste can't be got rid of, though cooking might help. Avoid freezer burn by wrapping food for freezing carefully in plastic freezer bags and squeezing out as much air a possible. Be sure the food, if damp, is patted dry before bagging. Always freeze in bags and transfer to rigid plastic or other containers, if required, once fully frozen.
