Pure Aluminium Foil: What You Need to Know

Aluminium foil is a common household item used for cooking, wrapping, and storing food. However, not all aluminium foils are created equal. To make sure you’re buying pure aluminium foil, you need to keep a few things in mind. In this article, we’ll explore how you can tell if aluminium foil is pure and why it matters.

Look for the Thickness

One of the easiest ways to tell if aluminium foil is pure is to look at its thickness. Pure aluminium foil tends to be thicker than its impure counterparts. While thin and flimsy foils may be cheaper, they’re also more likely to contain impurities that could affect your food. So, when buying aluminium foil, check its thickness and opt for a thicker one.

Check for Certification

Another way to ensure that you’re getting pure aluminium foil is to check for certification. Look for food-grade certification from trusted authorities like the US Food and Drug Administration (FDA) or the European Food Safety Authority (EFSA). Certified aluminium foils undergo rigorous testing to ensure that they don’t contain harmful substances like heavy metals or chemicals.

Perform a Burn Test

If you’re still unsure about whether your aluminium foil is pure, you can perform a burn test. Simply light a small piece of the foil with a lighter or match stick. If it catches fire and burns rapidly, it’s likely that the foil contains impurities. Pure aluminium foil, on the other hand, will burn slowly and won’t produce dark smoke.

Don’t Fall for the Shiny Side Myth

Contrary to popular belief, the shiny side of aluminium foil isn’t necessarily the pure side. The shiny and dull sides of aluminium foil are created during the manufacturing process and don’t indicate the quality or purity of the foil. So, don’t fall for the shiny side myth and focus on other factors to determine the purity of your aluminium foil.

Knowing how to tell if aluminium foil is pure is an important aspect of food safety. By checking the thickness, certification, and performing a burn test, you can ensure that you’re using pure aluminium foil that doesn’t contain harmful substances. Remember, pure aluminium foil may be a bit more expensive, but it’s worth the investment for the health and safety of you and your family.
