Can Aluminum Takeout Containers Be Microwaved?
Aluminum takeout containers are popular because they're lightweight, sturdy, and perfect for grab-and-go or meal prep. However, many people wonder if it's safe to use these containers in the microwave.
About Microwaving Aluminum
In short, the answer is no, you shouldn't microwave aluminum takeout containers. Aluminum is a metal, and placing it in the microwave can cause sparks or even fires. The metal can also interfere with the microwave's electromagnetic waves, causing the food to not heat properly.
While a small amount of aluminum foil can be used in some microwave cooking situations (for example, to cover food to prevent splatters), you should never place an entire aluminum container in the microwave. Aside from the safety issues, aluminum containers can damage the microwave, making repairs expensive.
If you need to reheat food in an aluminum container, transfer the food to a microwave-safe container, such as a ceramic or glass bowl.
Can You Microwave Styrofoam Takeout Containers?
Styrofoam restaurant takeout containers are commonly used for takeout food because of their ability to insulate and keep food warm during delivery. However, people often ask if Styrofoam containers are safe to microwave.
Why You Should Avoid Microwave Styrofoam?
Styrofoam, or expanded polystyrene (EPS), is not safe for microwaves. Microwaving a polystyrene takeout container can release decomposing harmful chemicals into the food. Additionally, some types of polystyrene melt at high temperatures.
According to the FDA, polystyrene containers may contain chemicals such as styrene and benzene, which are harmful to health. When polystyrene is heated in a microwave, these chemicals can leach into the food, posing a health threat.
Can You Reheat Plastic Takeout Containers?
Black plastic takeout containers are one of the most common types of takeout packaging. They come in all shapes and sizes and are often used to hold foods like salads, pasta, and even soup. But can you safely reheat food in plastic containers?
Is It Safe to Heat Plastic Takeout Containers in the Microwave?
The answer to this question depends on the type of plastic the container is made of. Not all plastics are microwave-safe, and some types of plastic can release harmful chemicals when heated. Here are some things to look out for:
- Microwave-safe plastics: Some plastic containers are labeled "microwave-safe" or have a symbol that indicates they are safe for use in the microwave. These containers are specially designed to withstand the heat of a microwave without deforming or leaching harmful chemicals. Always check the bottom of the container for the microwave-safe symbol before you microwave it.
- Plastics containing BPA: Older plastic containers or those not labeled as microwave-safe may contain BPA (Bisphenol A), a chemical that is hazardous to health. If your takeout plastic containers are not labeled that they are microwave-safe, it is best to avoid using them in the microwave to prevent the release of harmful substances.
- Plastic containers with lids: If you use a plastic container with a lid for microwaving, make sure the lid is also microwave-safe. Many plastic lids are designed to be heat-resistant, but they can still deform or release chemicals at high temperatures. Unless the lid is clearly labeled for microwave use, it's best to remove the lid before microwaving food.
Conclusion on Microwaving Plastics
To safely reheat food in clamshell takeout containers, always check if it has a microwave-safe label. If the container doesn't have a label, it's best to transfer the food to a more reliably microwave-safe container, such as glass or ceramic.
Safety Tips
While you now know the potential hazards of microwaving aluminum, Styrofoam, and some plastic containers, here are some general tips for safely reheating food in takeout containers:
Always Check for Microwave-Safe Labels
Look for containers that have a microwave-safe symbol or a label indicating that they are microwave-safe. This is the easiest way to avoid potential problems when reheating food.
Use Microwave-Safe Alternatives
If you're unsure about the safety of your takeout container, transfer the food to a microwave-safe plate. Glass and ceramic containers are great choices for heating food and are generally safe for use in the microwave.
Avoid Heating Containers with Metal Parts
Any takeout container with metal parts, such as aluminum foil or metal lids, should not be placed in the microwave. Metal can create sparks and cause fires.
Don't Overheat Plastic Containers
When using a microwave to heat plastic takeout containers, be sure to avoid overheating, as this can cause the plastic to deform or release harmful chemicals. Always watch when reheating food.
Check the Container for Deformation or Cracking
Before using any plastic container in the microwave, check for signs of wear. Over time, plastic can become brittle or deform from repeated exposure to high temperatures.
