What causes freezer burn?

Freezer burn happens when air reaches the food's surface and causes dehydration and oxidation, which manifests as grayish-brown leathery spots on frozen food. It is primarily caused by improper sealing that allows air exposure, not by the age or efficiency of the freezer.

How can I prevent freezer burn from happening?

To prevent freezer burn, ensure proper packaging by wrapping or using adequate containers before freezing. Maintain the freezer at -18°C or lower and check regularly for seal and vent integrity. Use vacuum-sealed bags to reduce air exposure, and always label food with dates for best usage.
