How to Keep Food Warm in a Lunch Box?
Here are our top ideas for how to easily store food for lunch so that it doesn’t get cold:
Insulated Containers
The best way to keep food warm in lunchboxes is to buy some insulated food containers. They perform similar functions to a thermos. Without using electricity or reheating, thermoses and insulated food containers can maintain the temperature of the food inside for a while. Usually, this is done by the container creating a tight vacuum seal that prevents hot air from escaping or by including insulated materials or lining in the container.
When searching for insulated containers, look specifically for containers with the word “insulated” in the description or look for food containers that are made of stainless steel. While some products will have top-notch insulated technology, stainless steel food containers will perform similarly. A stainless steel container will heat up when hot food is placed inside of it, keeping the food warm for several hours.
Boiled Water
Boiling water can also be used to heat a stainless steel food container so that your food will stay warm for a longer period of time. Boil some water in the morning before packing your lunch, and then pour the hot water into your stainless steel container. Until the food that will be placed in the container is heated, close the lid and leave the water to stand.
Warm up your food and then pack your lunch. Dry the interior of your container after emptying the hot water. Put the heated food in your insulated container, then tighten the lid. The food will stay warmer for a longer period of time in the stainless steel, which should be hot from the boiled water.
Foil
Wrapping hot food items in aluminum foil is an inexpensive way to keep them warm in a lunchbox. Even though foiling hot items won’t keep them warm for a long time, it will keep the food warm for a while.
Although foil isn’t technically insulated, it will temporarily warm up in temperature when hot food is placed inside, keeping the food warm at the same time. To keep the temperature warm for longer, you can also try wrapping the foil in a towel or piece of plastic saran wrap.
Hot Water Bottle
Use a hot water bottle to keep the food warm in a lunchbox. Commonly made of rubber or thermoplastic, hot water bottles have a hollow interior that allows for the addition of warm water. People who are feeling under the weather and want to relieve any aching body parts most frequently use hot water bottles.
Check for rips or holes before adding hot water to your hot water bottle. You can put water inside the bottle after giving it a thorough inspection. Never use boiling water. The material might become brittle when exposed to boiling water and might rip or sustain other damage. Fill your bottle with boiled, slightly cooled water, being careful not to overfill it.
It is advised to fill the bottle 3/4 of the way, then screw on the lid. Placing a hot water bottle at the bottom of your lunchbox and placing the food container you want to keep warm on top will help keep the food warm.
Insulated Thermal Bags
Insulated thermal bags essentially accomplish the same task—but better—as wrapping hot food in foil and a towel. It is simple to transport these thermal bags and they reflect heat back into the contents. Insulated thermal bags frequently come in packs and are on the more affordable end of the price spectrum. You can rinse a bag after using it and use it again several times, or if it gets too worn, you can throw it away and use a fresh, new one.
Insulated Lunch Box
Your insulated food containers should be kept in an insulated lunch box for added insulation. These days, it’s easy to find an insulated lunch box that matches your preferences and budget. The interiors of insulated lunch boxes may be waterproof, have multiple compartments, insulated lining, and special sections for heating packs or hot water bottles, among other features. Find out which insulated lunch box will suit your needs and budget by doing some research.
Separate Hot and Cold Items
Despite the space constraints, try your best to keep hot and cold items apart. Even if you already have separate containers for hot and cold food, you can further divide the two types of food using a physical divider. To create a subtle separation between your hot and cold containers, try using neutral objects like napkins or utensils. By doing this, you can guarantee that the temperatures in both of your containers remain as stable as possible.
The Best Temperature for Storing Food in a Lunch Box
There’s a “danger zone” of temperature, which ranges between 40°F to 140 °F (4.4°C-60°C). Even though there is a considerable gap, I strongly advise staying away from it.
Particularly in a small space like a lunch box, it is challenging to maintain the ideal temperatures for both hot and cold food. As a result, it would be best to avoid mixing these on the same day.
A thermometer should also be available so you can monitor and adjust the lunchbox’s temperature.
Hold The Warmth for Hot Food
The perfect temperature to preserve your hot food
Undoubtedly, hot food needs to be kept in a warm environment. Above the “danger zone”, which is 135°F is the ideal temperature for preserving hot food.
Hot food that has been left outside below the range of 135°F for over 4 hours is no longer edible.
To prevent cross-contaminants from appearing in freshly prepared and reheated food, separate the two.
Stay in Low Temperature for Cold Food
It’s hard to keep cold food to be fresh in a lunch box
On the contrary, to avoid the “danger zone”, cold food needs to be kept at a temperature below 40°F.
The shelf life of cold food in this condition is up to 6 hours. But remember to check the temperature regularly, because if cold food is exposed to outside temperatures for over 2 hours, it will spoil.
