How Safe Are Aluminium Foil In Wrapping Food
The International Food Packaging Association issued the "2013 China Food Packaging Safety Consumption Warning", 12 types of food packaging were accused of causing dangers to food safety and consumer health. Among them, the tin foil used for barbecue was first listed as a "potential killer" threatening health.
According to the International Food Packaging Association, tin foil or aluminum foil is mostly used to wrap food and barbecue to prevent the meat from being burnt. However, the main composition of tin foil is lead-tin alloy. The lead content in tin foil is as high as about 50%. The surface layer can also generate toxic lead white and lead hydroxide. When incineration, yellow lead (lead monoxide) is also a toxic compound. These toxic particles float in the air along with the hot air flow, and are inhaled in the respiratory tract and deposited in the lungs. Chronic lead poisoning can cause depression, anemia, kidney disease, infertility, miscarriage and other symptoms.
It is best to choose aluminum foil paper for barbecue, and its lead content should meet national standards. Aluminum foil and tin foil are easy to distinguish. Tin foil is much brighter than aluminum foil, but it has poor ductility and will break when pulled. Aluminum foil is relatively hard, and is mostly packaged in rolls, which is relatively cheap.
If seasoning sauce or lemon is added to the food, the acidic substances contained in it will precipitate the tin and aluminum of the tin foil or aluminum foil, which are easily mixed into the food and absorbed by the human body, which will cause tin and aluminum poisoning in the eater. Tin can irritate the intestines and stomach, and aluminum can cause dementia. If kidney patients consume too much aluminum, anemia may occur.
The International Food Packaging Association recommends that when making barbecued food, if you use foil or aluminum foil to wrap the food, do not add seasoning sauce or lemon. In addition, it is safer to use cabbage leaves and corn leaves instead of tin foil or aluminum foil, or use bamboo skins, water chestnut skins or vegetable leaves as substrates.
