What is freezer burn and how does it occur?
Freezer burn is a condition that occurs when frozen food is damaged by dehydration and oxidation. This happens when the food is not properly sealed or wrapped, allowing moisture to escape and causing the formation of ice crystals on the surface of the food. As a result, the food becomes dehydrated and develops a dry, leathery texture.
Freezer burn can also be caused by fluctuations in freezer temperature, which can cause the formation of ice crystals on the surface of the food. Additionally, freezer burn can be caused by the food being stored for too long in the freezer, as the quality of the food will degrade over time. It’s essential to store food properly and at a consistent freezer temperature to prevent freezer burn.
What is mold and how does it occur?
Mold is a type of fungus that grows on food, particularly in damp and humid environments.
