How to detect freezer burn
Look the food packaging.
An opening in the food packaging or a tear in the plastic indicate that the food has been exposed to cold, outside air, and has a higher chance of being freezer burned.
Inspect the food.
Remove the food from the packaging, and check the food for dry areas, areas of discoloration, and ice crystals. Food with any of these qualities, is highly likely to be freezer burned.
