Microwave safety: Items you should never heat up
Microwave ovens are an integral part of many kitchens. Their usefulness is undeniable, but there are things you definitely shouldn't put in them. Learn what not to heat in the microwave.
Microwave ovens have become essential in many homes, offering quick and convenient cooking solutions. However, improper use can lead to dangerous situations. Certain guidelines need to be followed to avoid potential hazards, such as damaging the device.
It's important to understand that a microwave is not just a device for heating food. It works by agitating molecules, which generates heat. However, not all materials are suitable for this process. Therefore, knowing which items should not be placed in the microwave is crucial.
Can using a microwave be dangerous?
One of the most common microwave hazards is putting metal objects inside. When metal comes into contact with microwave waves, it can cause sparking, possibly leading to a fire. This threat applies to metal dishes and mugs or plates with metallic decorations and aluminum foil.
The same caution applies to plastic. Not all plastic is microwave-safe. At high temperatures, toxic substances can leach into the food. Using improper plastic containers not designed for heating may release toxins that pose health risks. An example is bisphenol A (BPA), a chemical in plastic packaging that can transfer to food when heated, potentially causing hormonal disruptions.
Polystyrene containers can also be dangerous as they may melt and release harmful chemicals into meals.
The key is to adhere to the usage guidelines recommended by manufacturers and avoid using containers that lack appropriate labels. It's wise to choose dishes specifically marked as "microwave-safe"—these are made from materials resistant to microwave energy and do not release harmful substances.
Which food products should you not microwave?
A common mistake is placing whole eggs in the microwave. When exposed to microwave energy, steam pressure increases inside the shell, often leading to an explosion and creating a mess inside the appliance. This is a nuisance to clean and can damage the microwave.
Another less obvious example is fresh fruits like grapes. Despite their small size, grapes can explode in the microwave.
What to remember when using a microwave?
To avoid dangerous situations, following a few simple rules is helpful. The most important one is always to use dishes intended for microwave use. These dishes are usually made from ceramic, porcelain, or tempered glass, making them safe for health and resistant to microwave energy.
If you're unsure about the safety of a material, it's beneficial to conduct a test. Briefly microwave a container with water (for about 30 seconds). If the container becomes hot, it's a sign that it is unsuitable for use in this device.
