What is freezer burn?
Freezer burn is the result of air reaching the surface of the frozen patty resulting in a grayish-brown leathery looking spot.
At BARF World we use nitrogen freezing and you may notice discoloration. This discoloration should not be confused with freezer burn. When using a nitrogen freezing process the tunnel will cause a slight dehydration on the patty surface. This differs greatly from a badly discolored freezer burn.
The very best way to control this potential problem is to use good air sealed packaging to block the air movement on the surface of the patty. The answer is to only stock and use enough of the frozen diet to keep it looking fresh and properly colored.
