Is It Safe To Cook Food In Aluminum Foil

Is it safe cook food in aluminum foil? We should first make clear that it is aluminum ions that will affect our body. Only heating will not make aluminum foil precipitate the aluminum ions. What will? Learn more.

Is it safe cook food in aluminum foil?This question is just like another question: is it safe to walk on the street. It doesn’t have an absolute answer. We should understand: no food packaging is completely safe. The key is how to use.

To ensure people's safety, aluminium packaging for food is produced in full accordance with food safety requirements. Food grade aluminum foil is clean, hygienic and resistant to high temperature because of high melting point. Therefore, no matter storing food in aluminum foil or heating food in aluminum foil, it will keep the original taste of the food.

Aluminum foil paper is a relatively safer packagingaluminum foil food container.jpg material compared with others such as tin paper. Then where does the insecurity of aluminum foil food packaging come from? It is a cognitive error.

The effect of aluminum on the human body actually refers to free aluminum ions. For example, alu used in water will ionize and produce aluminum ions. Then the aluminum ions will react with hydroxide ionized by water to generate aluminum hydroxide. If such aluminum ions are taken in excess ( the excess is not easy for ordinary people), it will do harm to our body.

The melting point of aluminum is 660℃, far exceeding the temperature of most domestic ovens, and will not melt during use. Therefore, aluminum ions do not precipitate only by heating.

In addition, aluminum is a very active metal, so it is easily oxidized by oxygen in the air to produce alumina under normal temperature and pressure. Alumina is a dense protective film that can prevent some 1577263265135101.jpgsubstances from further corroding aluminum. In particular, foil packaging for food are all coated, and they will not cause any chemical action in the air, so they are very safe to use.

But there is one point we should pay attention to. When we aluminum foil for barbecuing or wrapping food, we should not add acid substances such as vinegar and lemon. Acidic substances will precipitate the aluminum ions of the aluminum foil paper and can be easily mixed into food and then absorbed by the human body, which will cause aluminum poisoning. The aluminum can cause dementia. If a kidney patient consumes too much aluminum, anemia can occur.

From the above information, it is not difficult to conclude it is safe to cook food in aluminum foil without the participation of acidic substances.
