Quick Answers

 

 

What is freezer burn?


Moisture loss or ice crystals evaporating from the surface area of a product produce freezer burn. Freezer burn appears as a fuzzy, grayish-white spot on the food surface. Freezer burn is not harmful but it causes off-flavors and dries out and toughens food. It can be prevented by wrapping food in moisture-vapor-proof material and storing it for the recommended length of time. Covering fruit with syrup and cooked meat with gravy or sauce also helps prevent freezer burn.
