Understanding Freezer Burn

The video explains freezer burn, a common issue with frozen foods, caused by sublimation where ice turns directly into vapor, leading to dehydration and discoloration. It suggests prevention methods like double-wrapping and using airtight containers. Despite freezer burn, the food remains safe to eat. The video concludes with a call to action for Patreon support and subscribing to SciShow.
