Can aluminum foil be used for freezing food?

Yes, aluminum foil can be used for freezing food. It is a common practice to wrap food in aluminum foil to protect it from freezer burn and to keep it fresh. The foil acts as a barrier, preventing air and moisture from reaching the food, which can cause freezer burn. It also helps to keep the food's original flavor and texture. However, it's important to ensure the foil is tightly wrapped around the food to be effective. For long-term storage, it's recommended to use airtight containers or plastic wrap in addition to foil, as foil can tear or become brittle in the freezer over time.
