Is It Ok to Put Hot Food in Plastic Containers: Avoid Ordinary Storages
You should avoid using ordinary plastic containers when storing hot food for several reasons.
- Reason 01: Chemical leaching
- Reason 02: Toxin release
- Reason 03: Potential environmental impact
Reason 01: Chemical Leaching
Putting hot food in ordinary plastic containers can increase the risk of chemicals leaching into your meal.
When hot food comes into contact with plastic, especially at higher temperatures, chemical compounds from the plastic can potentially leach into the food. The heat promotes chemical reactions within the plastic, causing the leaching to occur more rapidly and significantly.
Reason 02: Toxin Release
When exposed to heat, ordinary plastic containers can warp or degrade, releasing toxins or harmful compounds into your food. These toxins can contaminate your meal and, if consumed over time. It may contribute to health problems such as hypertension, insulin resistance, and metabolic disorders.
This is a significant concern as releasing such toxins can have long-term health implications, especially if hot food is routinely stored in plastic containers.
Reason 03: Potential Environmental Impact
For the sake of the environment, we must refrain from using ordinary plastic containers for hot food storage. These containers are typically made from low-density polyethylene (LDPE), which takes hundreds of years to break down in the environment.
When hot food is stored in these containers, the heat can cause the plastic to break down and release harmful chemicals into the food. This poses a health risk and contributes to the already significant problem of plastic waste and its detrimental effects on the environment.
Alternatives to Plastic Containers for Storing Hot Food
There are safer alternatives available for storing hot food in your kitchen. Here are some containers recommended by kitchen experts:
i. Glass Containers
Unlike ordinary plastic containers, glass doesn’t absorb odors, flavors, or chemicals from the food. It’s considered a safe alternative due to its non-porous nature and freedom from harmful chemicals.
Glass containers are also transparent, making it easy to identify the contents and reheat food safely in the microwave or oven.
ii. Stainless Steel Containers
Stainless steel containers are also excellent options for storing hot food. They’re durable, corrosion-resistant, and don’t react with acidic or hot foods.
Stainless steel containers are also eco-friendly as they can be reused and have a long lifespan. They’re also easy to clean and maintain, making them a practical choice for storing hot meals.
iii. Biodegradable Materials
When considering the safety of storing hot food, biodegradable materials offer a better alternative to ordinary plastic containers.
Biodegradable materials like PLA and Kraft paper containers are environmentally friendly and BPA-free. These materials are designed to withstand high temperatures, making them suitable for storing hot food in the kitchen.
iv. Ceramic Containers
For centuries, ceramic pots have been used in various cultures to store and serve hot food. These containers are excellent at retaining heat, keeping your food warm for longer. However, we recommended that they should be seasoned and used correctly to prevent cracking due to thermal shock.
v. Mud Filters (Matkas)
Using mud filters, such as Matkas, is safer than putting hot food in plastic containers. Matkas are made from natural clay and are designed to keep water cool. They can also be used for storing water-based foods like pickles.
Unlike plastic containers, clay mud filters are free from harmful chemicals that can leach into hot food and cause health risks.
How Do You Tell if a Plastic Container Is Hot Food Safe?
To determine if a plastic container is safe for hot food, you can follow a few tips we collected from our extensive research.
Tips 01: Check the Label
Look for specific indications on the label, such as ‘microwave-safe’ or ‘heat-resistant.’ Manufacturers often use these labels to signify that the container is designed for hot food use.
Also, some containers may have symbols, like a microwave icon, which can further guide their suitability for heating. We suggest paying attention to these labels and symbols as they indicate whether the plastic container is safe for use with hot foods.
Tips 02: Look for Food-Grade Plastics
We also strongly suggest carefully examining the plastic container to determine if it’s made from food-grade materials. Look for labels or markings on the container that indicate it’s made from food-grade plastics such as Polypropylene (PP) or Polyethylene Terephthalate (PET or PETE).
These materials have undergone testing to meet FDA guidelines and are considered safer for hot food storage. Food-grade plastics are designed to withstand higher temperatures without leaching harmful chemicals into your food.
Tips 03: Examine the Recycling Code
To determine if a plastic container is hot food safe, you should look for the recycling code and examine it closely. The recycling code is a number inside a triangle of arrows, typically found on the bottom of the container.
Regarding hot food, you should look for plastics with recycling codes #2, #4, and #5. These plastics, which include high-density polyethylene, low-density polyethylene, and polypropylene, are considered safer options for hot food storage.
In contrast, it’s advisable to avoid plastics with codes such as #1, #3, #6, and #7, as they can potentially contain harmful chemicals that may leach into your food when exposed to heat.
Tips 04: Conduct a Heat Test
During a heat test, you can determine if a plastic container is safe for hot food by filling it with hot water and observing for any signs of damage or odor.
- Simply fill the container with hot water below boiling point and let it sit for a few minutes.
- Afterward, carefully examine the container for warping, distortion, or unusual odors.
- If the container maintains its shape and doesn’t show damaged or bad odors, it may be safe for storing hot food in the kitchen.
Frequently Asked Questions
1. Is it safe to drink hot water in plastic bottles?
Following certain guidelines, you can safely drink hot water in a plastic bottle.
You should choose a bottle designed to handle hot liquids, such as those made from polypropylene or high-density polyethylene. Also, ensure the bottle is in good condition without any cracks or scratches, which can increase the likelihood of chemicals leaching into the water.
