In this comprehensive guide, we’ll delve into the world of freezer burn, exploring the signs, causes, and prevention methods to ensure your frozen food remains safe and delicious.
What is Freezer Burn?
Freezer burn, also known as freezer scorch or freezer dehydration, is a condition that occurs when frozen food is exposed to warm air, causing the water inside the food to evaporate and leave behind a dehydrated, discolored, and often inedible product. This can happen due to various factors, including inadequate packaging, poor storage, and prolonged storage times.
