Plastic is a common choice for food storage, but it has come under scrutiny for potentially harmful chemicals, such as Bisphenol A (BPA). These chemicals pose health risks, making it critical to understand which plastics are safe for food storage.
Identifying safe plastics starts with the recycling code, which can be found on the bottom of containers and ranges from 1 to 7. Plastics assigned the numbers 2, 4, and 5 are considered the safest options for storing food as they minimize the risk of toxin exposure.
Food-grade plastics must comply with specific regulations that ensure they are free from harmful additives or dyes. For example, food-safe plastics may contain recycled materials, provided they adhere to safety guidelines established by the Food and Drug Administration (FDA).
The FDA has identified several types of food-safe plastics, including:
HDPE is well-regarded for its chemical resistance and safety in food applications. Containers made from HDPE do not leach potentially harmful chemicals, making them ideal for storing a variety of food items.
LDPE is similarly non-toxic and safe for food contact. Used in items like bread bags and produce bags, LDPE’s chemical-resistant properties prevent leaching into food.
PET is praised for its strength and stability. It is commonly used for single-use beverage bottles and food containers. However, caution should be exercised when reusing PET containers, especially if exposed to high temperatures.
Polyethylene, while generally safe, should not be left in hot environments that could cause it to degrade, releasing toxins. Therefore, it is advisable not to reuse certain types of polyethylene containers, particularly those made from polystyrene.
Polypropylene is highly durable, making it suitable for a variety of food storage applications, including containers for dairy products. Its ability to withstand high heat makes it microwave-safe, adding to its versatility.
Polycarbonate is known for its strength and heat resistance, which allows it to be FDA-compliant. Common uses include baby bottles and water coolers. Despite occasional concerns regarding BPA, the amounts present are generally low and deemed safe under usage guidelines.
Acrylic is another strong material that is FDA-approved for food storage. While safe, it is important to note that acrylic containers should not be used in the microwave due to their lower heat resistance.
Nylon is another commonly used food-safe plastic, offering heat resistance suitable for cooking utensils. It does not leach harmful chemicals, enhancing its safety profile.
For safe food storage, prioritize plastics labeled with recycling codes 2 (HDPE), 4 (LDPE), and 5 (PP). Avoid containers marked with codes 3, 6, and 7, as these may pose health risks.
For those seeking eco-friendly options, alternatives such as glass, stainless steel, and silicone offer great alternatives. These materials avoid the risks associated with plastic while providing safe food storage solutions.
