Aluminum foil rolls are light, shiny, strong in reverse ability, good in barrier properties, strong in adaptability to temperature, stable in shape at high or low temperatures, strong in light-shielding, and excellent in fragrance retention. That is why is aluminium foil used to wrap food. However, many people still have doubts about safety of aluminum foil for food wrapping. Is aluminium foil safe to wrap food, anyway?
In the first place, aluminum foil can not be used to wrap some foods containing ingredients that will definitely not work if they react with aluminum, although the surface of the aluminum foil is indeed treated with an oxide film to protect it. Aluminum is an easily oxidizable metal. It has an oxide layer on the surface of the aluminum foil, so that the aluminum ions are tightly fixed by the oxide layer, so that it cannot escape; it further improves the safety of our use of aluminum foil. But keep in mind, try not to touch the aluminum foil or aluminum with strong acid items, because the acid will destroy its oxide layer.
Second, aluminum foil packaging and wrapping has been popular for half a century in many countries in Europe, America, the Middle East and other regions. It has also been widely used in many industries such as domestic aviation, hotels, and West Point cooking. Its worldwide user population is very large. In addition, China, as a major exporter of aluminum foil products, also has world-leading technology in the aluminum foil packaging industry. The products it produces are fully in line with national food packaging safety.
Finally, as emphasized by many scientists, “No food is absolutely safe, and no food is free of any hidden dangers.” At present, it seems that no authoritative institution has experiments to prove that aluminum foil does harm to the human body. The so-called negative effect of aluminum on the human body actually refers to free aluminum ions. For example, the alum used to make rice noodles into rice noodles also becomes aluminum hydroxide. If such aluminum ions are taken in excessively (note that the precondition is excessive dosing , which is not easy for ordinary people to reach), they will cause certain health problems.
So rest assured. Wrap beef and vegetables with aluminum foil as much as you like at a barbecue. Believe in science and practice, don’t scare yourself.
