The truth about reusing takeout containers
If you enjoy takeout and delivery food, your kitchen may be overflowing with plastic food containers. And while some orders come in a disposable carton or Styrofoam box that you just toss, others were served in containers that may be too sturdy to be disposable. Should you save those?
Why food professionals love reusable takeout containers
Food professionals seem to love their takeout containers because of their versatility and because glass containers aren’t allowed in most kitchens (they break). Chef Jeremy Umansky likes reusable takeout containers because they can hold just about anything from sauces to fried rice, but also because they can be used as organizers for small kitchen appliances whose parts can fall off and hide under a prep counter or cabinet. As Food 52’s Allison Bruns Buford puts it, “If you have the full range-a quart, a pint, a half-pint, you basically have a container for every storage need,” not only because they stack well, but also because there’s nothing quite like eating right out of one.
The Safety of Reusing Takeout Containers
If you’re the kind of person who likes to store leftovers or pre-prepared meals in recycled deli containers, there are a few things food scientists think you should know. Deli containers are made of polypropylene, the second most commonly used plastic after polyethylene, which is what plastic bags are made of. “Polypropylene is supposed to be one of the ‘safer’ plastics,” says Caroline Cox, a scientist with the California-based Center for Environmental Health. “One of the biggest problems is that we don’t really know what’s in these containers, and neither do the restaurants that use them.” To make matters worse, other chemicals are added to the raw plastic before it is made into deli containers.
Using takeout containers safely
None of these chemicals should be a problem if takeout containers are used to store dry goods like rice or beans. They can also be used safely in freezers because they can be exposed to freezing temperatures for long periods of time. But while they can be labeled as freezer- or dishwasher-safe, it’s not a good idea to put deli containers in the microwave, where toxins can leach out of the plastic. “There’s a pretty big gap in what people know about plastics and food safety,” Cox tells Food52.
When to say goodbye to takeout containers
If you take good care of your takeout containers, they can last a few months. And you’ll know it’s time to say goodbye when they start to crack, warp, discolor, or smell.
Reusing takeout containers can be a convenient way to store and organize your food, but it’s important to be aware of the potential risks associated with certain types of plastics. While polypropylene containers are generally considered safe for dry storage and freezer use, caution should be exercised when using them in the microwave. The exact composition of these containers is often unknown, and the additional chemicals used in their manufacture may pose a risk when exposed to high temperatures.
To ensure food safety, it’s a good idea to transfer food to microwave-safe containers before reheating. In addition, inspect your takeout containers regularly for signs of damage or deterioration. If they become cracked, warped, discolored or develop an unpleasant odor, it’s time to throw them away and replace them with new containers.
Understanding the materials used in takeout containers and their limitations can help you make informed decisions about reusing them in a way that balances convenience and safety. Remember to put your health and well-being first when it comes to storing and reheating food, and always follow the guidelines provided by food safety experts.
FAQS
Are all takeout containers safe for reuse?
Not all takeout containers are created equal. While some containers, particularly those made of polypropylene, are generally considered safer for reuse, it’s important to exercise caution and be aware of the specific materials and limitations of each container.
Can I safely microwave food in reusable take-out containers?
It is generally not recommended to microwave food in reusable takeout containers because the heat can cause toxins to leach from the plastic. It’s best to transfer food to microwave-safe containers before reheating to ensure food safety.
Can I put any type of food in reusable takeout containers?
Reusable takeout containers are great for storing dry foods like rice or beans. However, it’s important to avoid storing highly acidic or fatty foods, as these can cause the plastic to degrade and potentially contaminate the food.
How long can I use a takeout container before I need to replace it?
The life of a takeout container depends on how well it is cared for. With proper maintenance, such as regular cleaning and avoiding excessive heat exposure, a container can be reused for several months. However, it’s important to monitor the container for signs of damage or deterioration and replace it when necessary.
Are takeout containers safe to use in the freezer?
Yes, many reusable takeout containers are labeled as freezer safe and can safely withstand sub-zero temperatures. This makes them suitable for storing leftovers or pre-prepared meals in the freezer for extended periods of time.
How can I ensure the safety of my reusable takeout containers?
To ensure the safety of your reusable takeout containers, follow these guidelines: avoid microwaving food in them, inspect them regularly for signs of damage, avoid storing highly acidic or fatty foods, and replace them if they become cracked, warped, discolored, or develop an unpleasant odor. In addition, consider using microwave-safe containers for reheating and put your health and well-being first when it comes to food storage and safety.
