Why is one side of aluminum foil matte and the other shiny: Are you using the wrong side?

Sometimes we need to rethink the use we make of some of the objects or tools that have been with us all our lives. Whether through carelessness or because no one taught us properly, they may be being used incorrectly. This is thought to sometimes happen with aluminum foil, Few people understand the difference between its two faces..

If you take the aluminum foil, you will see that One side is shiny and the other is dullbut do you know what each one’s function is and how you should wrap the food you store? We are going to explain it to you in a very simple way so that you don’t forget it, since everything has its reason.

Although before doing so we want to point out that If the purpose of the aluminum foil is to cook or heat something in the oven, you don’t have to worry. because they are equally effective when used.

When aluminium foil is manufactured, the process of stretching the sheet takes place, as well as reducing its thickness so that it can be packaged as it reaches customers.

At that time, as they point out in Reader’s Digestis when the distinction between both sides occurs: “The bright side It is the milled side without being in contact with another sheet of metal. The performance of the foil is the same, regardless of which side you use.“.

However, there have always been comments or hoaxes that some aluminum foil was harmful or toxic for food when wrapping it.

From the OCU They conducted research on this and were very clear in their conclusions: “is It is absolutely false to claim that one side of the aluminum foil and the other are different. and they have different properties. They are exactly the same except for the color, and aluminum foil is equally effective on both sides.“.

The difference in use should only occur in non-basic aluminum foils, such as non-stick foils, where there is a layer that should not touch the food. With the rest, the one you probably have at home, it doesn’t matter which side you choose.
