Aluminum foil, also known as aluminum foil, commonly known as tin foil, tinfoil, etc., is made of flattened aluminum. It is mainly used in the kitchen for cooking, holding food, or for making some materials that can be easily cleaned. Aluminum foil is used in large quantities around the world to protect and package food, cosmetics and chemicals. Most aluminum foils are shiny on one side and gray on the other. Aluminum foil paper for food can be used to wrap food on both sides. It is usually recommended to wrap food on the glossy side to improve the heat conduction effect.
Aluminum foil is usually used to hold food (such as aluminum foil plates). It is used to wrap bean sprouts, potatoes, sweet potatoes, etc. for grilling to prevent them from burning. Sometimes used for decoration. Modern aluminum foil paper is made of aluminum and can also be used as aluminum electrodes for electrolysis. There are also hairstylists who use aluminum foil to perm customers' hair. Some people also use aluminum foil to absorb the oil in the soup. Aluminum foil is also widely used as an isolation layer, heat exchanger, and as an electrical conductor. Usually, the thickness of aluminum foil used in paper beverage packaging and food packaging bags is only 6.5 microns. This thin layer of aluminum repels water, preserves flavor, and resists bacteria and stains.
contain food
It is very common to use aluminum foil plates to serve food. Although aluminum foil plates are disposable tableware, they are made of aluminum and are less harmful to nature.
barbecue
Some foods (such as sweet potatoes, enoki mushrooms, etc.) must be wrapped in aluminum foil to avoid burning. Wrap them in aluminum foil to grill seafood, enoki mushrooms, etc. to retain their flavor.
Electric hair
Some hairstylists wrap their hair in aluminum foil to heat it, which has a better heat transfer effect. Improper use of aluminum foil hair dryers can cause burns, poor hair quality and other problems.
absorb oil
Roll the aluminum foil into a ball and open it to absorb the oil floating on the surface of the soup. [3]
chemical reaction
Aluminum foil, like aluminum cans and aluminum pots, will react with acid (usually organic acid), and the salt produced by aluminum and organic acid will react with gastric acid to generate aluminum chloride (AlCl3).
