Heating aluminum foil can produce toxins.
Because aluminum foil will contain a certain amount of aluminum and lead, heating may produce a chemical reaction, so that aluminum, lead and other metal substances overflow, although the amount of a time is less, but the metabolism of metal substances in the body is very slow, if long-term consumption, may cause poisoning; If the food is wrapped in tin foil or aluminum foil during grilling, the acidic sauce on the food and the aluminum and tin foil are heated at the same time, and the chemical reaction will be faster.
Precautions for the use of aluminum foil
When using aluminum foil, it is necessary to distinguish between front and back, bright for the front and matte for the reverse. Since the matte surface reflects less light and absorbs more heat outward, the matte side should be used to contact the food when wrapping the food, and the bright side should be exposed. In addition, contact with acidic and alkaline spices or foods should be avoided as much as possible. Such as vinegar, lemon, baking soda, etc., to avoid chemical reactions and generate aluminum salts.
Aluminum foil is widely used, such as: aviation food packaging, ordinary meat packaging, cigarette roll packaging, etc. As an industrial manufacturing raw and auxiliary material, aluminum foil is mainly used in packaging protection, daily necessities, construction, etc.
