Intro: Freezer burn looks bad but is harmless — and easy to prevent.
1. Wrap food tightly
Air exposure causes freezer burn.
2. Use freezer bags
They protect better than containers.
3. Don’t freeze warm food
Steam creates ice crystals.
4. Label and rotate
Old food burns faster.
5. When to trim
Cut off burnt edges before cooking.
Summary: Freezer burn happens when food is exposed to air or moisture.
