Aluminum Foil Just keep in mind the foil will keep in the heat for only about 30 minutes or so. If you are trying to keep a roast, steak, or whole bird warm, tenting with aluminum foil while it rests will benefit the meat in two ways: It will keep it at a warm temperature while allowing the juices to redistribute.
This range of temperatures is often called the Danger Zone. Never leave food out of refrigeration over 2 hours.
Best way is a highly insulated container, especially a vacuum container with superior heat holding ability. You could also use a closed container in a hot place like an oven (140F+ remember), or even on the side of a car engine. Also, you can hold it in a steamer / bain marie)/ double boiler.
In general, it is not recommended to wrap hot or acidic meals in aluminium foil because the aluminium may leach into the food and contaminate it. However, using a high-quality foil, such as the one from Asahi Kasei, prevents this from happening.
Though hot foods can be kept for long periods of time at or above 140°F, the texture and flavor profile of food will likely start to degrade after about an hour. Food in smaller quantities or dishes that are heat-prone shouldn't be kept warm in the oven for more than 30 minutes.

The best plan is to put leftovers in the refrigerator right after your meal. Food that is sitting out for a party or picnic should be chilled after two hours at typical room temperature. If it's above 90 degrees Fahrenheit (32 degrees Celsius) or more, food should not sit out for more than one hour.
Safe Practices For Wrapping Food In Tinfoil
Use aluminum foil primarily for short-term storage. Avoid wrapping acidic or salty foods directly in foil; consider using glass or BPA-free containers instead. For longer storage, use foil with an airtight container or plastic wrap.
Foil does not burn, but it can melt at 1220°F. Be cautious when grilling at high temperatures, as closed grills can reach the melting point of aluminum foil.
Keep hot food in oven-safe baking dishes until other meals are ready. Leave the lid on to trap heat inside and keep the food warm. If you have the space, place the dishes in the oven or warming drawer at a very low temperature. Place items on preheated baking trays.
There is in fact a hot holding exemption that means that you can keep food that is to be served hot, below 63°C for one period of up to two hours. You must take care not to exceed the two hours because otherwise you could cause a risk to the health of your customers.
Food held between 5oC and 60oC for less than 2 hours can be used, sold or put back in the refrigerator to use later. Food held between 5oC and 60oC for 2-4 hours can still be used or sold, but can't be put back in the fridge. Food held between 5oC and 60oC for 4 hours or more must be thrown away.
ServSafe states that 4 hours is the maximum length of time ready-to-eat foods can stay in the temperature danger zone. After the 4-hour limit, foods are considered spoiled and must be thrown away. Within the 4-hour time limit, foods can be consumed, reheated, or chilled to bring them back to food safe temperatures.
Bacteria can grow rapidly on food left out at room temperature for more than 2 hours. If food is left out in a room or outdoors where the temperature is 90 degrees F or hotter, food should be refrigerated or discarded within just 1 hour. Myth: When I microwave food, the microwaves kill the bacteria.
It's important to avoid using aluminum foil with acidic foods like tomato-or vinegar-based dishes, citrus fruits, or marinades containing citrus juices. Acidic ingredients can corrode the foil, causing aluminum to leach into the food, which may result in a metallic taste.
It is permissible to hold hot food without temperature controls for up to four hours if the following conditions are met: Food must be held at 135 degrees Fahrenheit or higher before the food is removed from the temperature control. Label the food upon receipt with the time it must be discarded.
One of the most common concerns about using aluminum foil is whether it can leach into food when heated at high temperatures. Aluminum foil can be safe when used at temperatures below 400-450°F (200-230°C). However, when these temperatures are exceeded, the risk of aluminum leaching into food increases.
But studies have shown that when aluminum foil comes into direct contact with food, particularly hot, acidic, or salty foods, it can release aluminum particles.
Never leave food out for more than two hours.
Wrap your food in tin foil and a towel.
Finally, wrap 2-3 towels tightly around the food and foil. Depending on the food, this can keep things nice and toasty for anywhere from 30 minutes to 2 hours. If you don't have thick tin foil, wrap multiple layers of regular tin foil instead.
Health Risks of Aluminium Foil
Leaching of Aluminium into Food: When food is wrapped in aluminium foil, especially hot, acidic, or spicy foods, aluminium can leach into the food. This is particularly concerning because aluminium is a neurotoxic metal.
Food that has not been used within two hours, should either be reheated until it is steaming hot and put back in hot holding or chilled down as quickly as possible to 8°C or below. If it has been out for more than two hours throw it away. Remember to keep the food at a safe temperature until it is used.
With rumination, the food is undigested. It often still tastes the same as when it was first eaten. The symptoms of rumination syndrome may look like other health conditions or problems. Always talk with your healthcare provider for a diagnosis.
As painful as it may sound, the FDA says the proper thing to do is to discard cold and hot food that has been left out at room temperature for longer than two hours or for longer than an hour when the mercury rises above 90.
