Freezer Burn Explained: Prevention Tips That Actually Work

Freezer burn happens when frozen food becomes dehydrated and oxidised, leaving dry patches, tough textures and a faded appearance. The good news? It’s totally avoidable with a few simple habits.

What Causes Freezer Burn?

Freezer burn occurs when air reaches the surface of frozen food. This leads to moisture loss and ice crystals forming on the outside. It’s safe to eat – but the quality suffers.

How to Prevent Freezer Burn

  • Wrap food tightly: Remove as much air as possible from bags and containers to keep moisture locked in.
  • Use airtight packaging: Freezer bags, vacuum-sealed packs or tightly wrapped foil help prevent air exposure.
  • Cool food before freezing: Warm dishes release steam, creating ice crystals that contribute to freezer burn.
  • Label and rotate: Use the “first in, first out” rule to avoid items sitting too long in the freezer.
  • Keep your freezer full: A well-filled freezer maintains temperature better and reduces air circulation around food.

Can You Still Eat Food with Freezer Burn?

Yes – freezer-burnt food is still safe. However, texture and flavour may be affected. Trimming off the dry areas usually makes food perfectly usable in cooked dishes.

When to Throw Food Away

If food smells off, shows signs of spoilage, or has been frozen far beyond recommended times, it’s best to discard it.
