Microwave mishaps: What not to heat and how to stay safe
Microwave ovens are an integral part of many kitchens. Their usefulness is undeniable, but there are things you definitely shouldn't put in them. See what not to heat in the microwave.
Microwave ovens have become an essential feature in many homes, offering quick and convenient kitchen solutions. However, improper use can lead to dangerous situations. There are certain rules that 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. Its design makes it work by agitating molecules, which generates heat. However, not all materials are suitable for this process. Therefore, knowing which products should not be placed in the microwave is extremely important.
Can using a microwave be dangerous?
One of the most common hazards when using the device is putting metal objects in the microwave. When metal comes into contact with microwave waves, it can cause sparking, which can even lead to a fire. This threat applies to metal dishes and mugs or plates with metallic decorations and aluminum foil.
The same situation applies to plastic. Not every plastic is microwave-safe. Under high temperatures, toxic substances can leach into the food. Improper containers made of plastic not suited for heating can release toxins that may pose health risks. An example is bisphenol A (BPA), a chemical used in plastic packaging that can transfer to food when heated and lead to hormonal disruptions.
Polystyrene containers can also be dangerous, as they may melt and transfer harmful chemicals into meals.
The key is to adhere to the usage guidelines recommended by manufacturers and to avoid using containers that do not have the appropriate labels. It's worth choosing 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?
One mistake is placing whole eggs in the microwave. When exposed to microwave energy, the steam pressure increases inside the shell, often leading to an explosion and making 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, it's worth applying a few simple rules. The most important is to always 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 worth conducting a test. Briefly (about 30 seconds) microwave a container with water. If the container becomes hot, it's a sign that it is not suitable for use in this device.
