ELI5: Why does food get freezer burnt when left in a freezer for too long?
gpt
Expanding ice crystals pierce and shred the cells that make up the food in the freezer. Longer stuff is in the freezer, the longer these ice crystals can grow. Essentially, when thawed, you've lost all cellular integrity. Freezers also are very dry. Moisture is wicked out of the food stuff as rhe cell walls are pierced. This 1 2 double whammy is what people call freezer burn.
