Aluminum tableware has a small amount of aluminum ions dissolved in the water during use, but as long as it is used properly, the aluminum dissolved in the water is less than one milligram per liter of water (food), which will not affect people's health. Because metal aluminum will naturally form a tough aluminum oxide film in the air, which prevents food from coming into contact with tableware. Someone has calculated that drinking all the boiled water from an aluminum pot during the year does not consume as much aluminum in the body as the aluminum in a fried dough stick. But if you use aluminum products to cook foods that contain acid, alkali, or a lot of salt, the situation is different, because acid, alkali, and salt will destroy this film, which will not only destroy the tableware, but also make more aluminum dissolve in the water. ,affect health.
Aluminum is soluble in acid and alkali. Common aluminum cooking utensils such as aluminum pans, aluminum boxes, aluminum pots, etc. can dissolve aluminum into food in large quantities after being exposed to acid, alkali, and salt. As aluminum cookware is light and soft, it is easy to scratch, it is best not to wipe with steel wire or use alkali and sand to clean aluminum cookware. Do not use aluminum spatulas, aluminum rice spoons and other utensils, because they produce invisible aluminum scraps during the long-term scratching of cooking and serving rice, and these aluminum scraps enter the human body with the entrance of the food. Thereby increasing the chance of people ingesting aluminum. For the health of the body, experts recommend using stainless steel cookware, because stainless steel products have stable metal properties and are harmless to the human body.
The correct operation method must be adopted when using aluminum products:
①Aluminum cookware should avoid rubbing with other hard objects to prevent aluminum powder from falling off. Aluminum cookware is not suitable for cooking.
② Heat the aluminum pot slightly before use to re-oxidize the damaged area of the oxide layer, which can reduce aluminum seepage.
③Aluminum container is not suitable for long-term storage of condiments and beverages.
④ The time for cooking food in aluminum pot should not exceed 4 hours.
⑤After the aluminum cookware is used up, clean it and bake it with fire to keep the oxide film intact.
⑥Food scraped with aluminum spoons and shovel contains aluminum crumbs and is not suitable for consumption.
