Can you microwave aluminum tray?

I’ve been wondering if it’s safe to use foil pans in the microwave for a while now. I’ve heard conflicting views from various sources and I’m not sure what to believe so I thought I’d do some experiments and research and share my results with you. This is what I discovered. Can you microwave aluminum tray?

Can you microwave an aluminum tray?

You can heat an aluminum tray in the microwave. The Fraunhofer Institute (IVV) in Freising, Germany, conducted experiments on this phenomenon and found no cases of dangerous outcome or damage to microwave ovens even when the trays were heated on full power 

. However, there are a few things to keep in mind if you decide to use an aluminum tray in your microwave: You

  • must remove the aluminum lid before placing the tray. Leaving the lid on while microwaving could cause an electrical arc, which can damage your microwave oven or even start a fire. .
  • You should place the tray in the center of your oven so that the tray does not come into contact with the microwave and the oven walls for the same reason as stated above.
  • You can only use one tray in your microwave at a time. Do not stack multiple trays or other aluminum cookware in the microwave

What happens when you heat an aluminum tray in the microwave?

I decided to do some experiments to see what would happen when I microwaved foil trays. When I placed a foil tray of food in the microwave, the microwave bounced off the tray and didn’t seem to hit the food.

The only way the microwave could get to the food on the tray was through the opening at the top. This is the reason why you should not cover the tray; the lid prevents microwaves from getting into the food.

Another observation I made was that there were no sparks to be seen unless the tray was touching the side of the microwave, which could be dangerous to your oven.

What do the experts say about aluminum microwave trays?

To further clarify the safety of aluminum microwave trays, I did some research and found some interesting facts and insights from prominent sources like the United States Department of Agriculture (USDA) and the Fraunhofer Institute for Process Engineering and IVV Packaging. in Freising, Germany.

is what the USDA says explicitly about microwaving aluminum foil pans:

“It may be safe to use small amounts of aluminum foil in a microwave oven.”

This claim is further supported by the Fraunhofer Institute study, where it states:

“Based on physical perception and empirical findings, all studies reviewed agree that there is no reason NOT to use aluminum foil packets to heat food in the oven. microwave oven. as long as some design rules and heating guidelines are followed.”

But what about the common idea that microwaving a foil pan can break your microwave?

From the same study that has been carried out for the European Aluminum Foil Association, it is stated that:

6 Tips for Microwaving Food

Safely in Aluminum Foil Pan As mentioned above, it is safe to use aluminum foil pans in the microwave as long as you adhere to certain instructions. So here are some helpful tips for using the tray in the microwave safely:

  1. The aluminum tray should be placed in the center of your microwave so that it does not touch any side of the microwave walls.
  2. Only use a shallow aluminum pan that is no more than 2 inches deep. This is to make sure that the food is heated evenly.
  3. Never microwave an empty aluminum tray. You should always put some food on the tray, and the food should cover at least 75% of the surface of the tray. This is because without food there is nothing to absorb the microwaves, which causes the microwaves to bounce back and forth off the oven walls, potentially damaging the oven.
  4. Do not leave the microwave unattended while heating food on an aluminum tray. If it arches during the microwave, you should be around to turn the microwave off immediately.
  5. Leave the top of the aluminum tray open. If you put something like aluminum foil on the foil pan, the hot foil pan can potentially catch the foil on fire.
  6. Last but not least, if your microwave is equipped with a metal turntable, you should place a ceramic or glass under the tray so that it does not come into contact with the metal turntable. This is to prevent sparking.

Can cooking food in aluminum in the microwave cause cancer or health problems?

This is another topic that has been on many people’s minds, and for this issue we will share with you insights from two other sources:

  1. A study published by Deutsches Ärzteblatt International, the official international bilingual scientific journal of the German Medical Association . summarized that the body absorbs only 0.1% of aluminum injected orally. This is a very small percentage, and there has not been enough evidence to show that this dose triggers or causes health problems. 
  2. The European Food Safety Authority (EFSA) and the World Health Organization (WHO) have also declared that it is tolerable to ingest between 1-2 mg of aluminum per kg of body weight weekly without any health problems.

Bottom Line

In summary, it is safe to use aluminum pans when heating food in the microwave. As long as you follow the safety instructions to the letter, it is unlikely that you will face any safety issues or cause any damage to your microwave oven.

It is safer from a health standpoint than microwaving food in plastic, paper, or Styrofoam containers, and there is no evidence that microwaving food on aluminum trays causes cancer or health problems. of health.

So there’s no reason why you can’t heat up your favorite food on a foil tray in the microwave.
