Aluminum foil has long been our preferred method of packaging for storing ready-made food or transporting food when traveling. But have you ever wondered how it keeps food warm and whether it's safe to store food in aluminum foil for long periods of time?
Aluminum foil is made of aluminum (as the name implies), which has reflective properties and acts as a barrier to light and oxygen. As a result, the foil reflects heat back into the food, retaining its natural aroma, moisture and flavor. It is often used to package fresh produce and dairy products to extend storage time.

If the foil comes in contact with the object, heat will move within the foil and may escape, but if the foil is placed a little further away from the food, it will properly reflect back the heat and keep the food fresh. To avoid contact between the foil and the food, add several layers of butter paper to create air pockets before loading the final layer of foil.
Because aluminum is a poor insulator (a substance that does not allow heat to pass through), place it (food wrapped in foil) in a fiberglass or ceramic tiffin box to make it more effective. It not only keeps the food warm longer, but also keeps it cooler. It acts as an oxygen and air barrier, allowing heat to transfer to cold or frozen foods. The bottom line is that it helps keep food warm, whether hot or cold. Because you will be storing food in it, you need quality aluminum foil.
