Jul 06, 2018. aluminiumstrip Leave a comment. Aluminum foil does not make food warm. It can keep food warm longer by trapping the hotter air inside, which then serves as an insulator, and by preventing interchange of the hot air inside with cooler air. Aluminum foil itself conducts heat very well so it isn an insulator itself.
Answer (1 of 5): Because conduction isn the only source of heat loss. As you suggest, foil provides almost no insulation. Now, it may trap a thin layer of air around the food, which would provide some insulation, but that not the primary purpose. When
An aluminum foil keeps the food warm, but placing the foil directly on the object or food doesnt help much. It doesnt only keep the food warmer for long, but also keep things cold.It acts as barrier to the oxygen and air which can transfer heat to the cold or frozen food.
Jul 08, 2019.Being a shiny surface the aluminium sheet reflects radiant heat and reduces the heat loss by radiation by as much as $90\%$.. Being impermeable the sheet stops the movement of hot air from the vicinity of the surface of the food into the surrounding by convection currents.
Warming Alternatives. Instead of foil, use insulated plastic containers to keep foods warm for up to two hours, a feat that foil could not achieve alone. You can also store multiple foil-wrapped foods in an insulated place like a cooler. The coolers dense insulation system will hold in the heat leaking out from the foil-wrapped foods.

Answer: It really doesnt matter that much. Aluminum conducts heat very well and the difference in reflectivity is insignificant. The purpose of the aluminum foil is to contain the liquids associated with the hot food, so the best option is to place an insulator around the outside. For example,
Jan 26, 2011. luminum foil is not the best insulator, but it better than no insulator at all. Aluminum foil insulates best when it traps a dead air space above (or around) the food product, explains food processing engineer Timothy Bowser. ne of my favorite tricks is to cover a hot (or cold) dish with aluminum foil and then add a
That is, the hot thing warms up the air. The hot air rises and creates a flow that carries heat away. Putting almost anything over the food stops the air from flowing, and so limits the heat loss. As for why foil specifically is used, I suspect its because its relatively cheap and easy to shape so that its not in direct contact with the food.
Answer (1 of 4): It isolates the food from air. The air oxidates the food, which is the cause of the food rottening.

Hotter air means that it can bounce all the better off the aluminum foil, transferring heat by conduction. And as you already noted, the aluminum will do a good job of conducting the heat toward the potato. So the potato heats up.
