The tinfoil used for making dishes should be food-grade "tinfoil". Its essence is actually aluminum foil. Using aluminum commonly known as "tinfoil" to barbecue and grill fish, as long as the product quality is up to standard, it is actually safer than direct barbecue. However, according to media reports, nearly 60% of standard paper on the market contains excessive amounts of lead, and When tinfoil is heated to high temperatures, heavy metal elements will be released, which can cause damage to the brain and kidneys. Qualified food-grade "tinfoil" actually does not contain lead or tin. It is made of flattened and filled Jinwu pure aluminum and is mainly used for steaming vegetarian barbecues and wrapping and holding food. The original "tinfoil" was indeed made of tin, but as the price of aluminum dropped, aluminum foil with superior performance replaced tin foil and became the first choice for all types of flexible packaging.
Aluminum waste has the advantages of moisture-proof, air-tight, light-shielding, abrasion resistance, fragrance retention, non-toxic and tasteless. According to industry insiders, aluminum waste is divided into food grade and industrial waste. During the production process, some gold particles may be mixed in. Elemental impurities. These metal elements are combined with aluminum elements to form metal compounds. When heated, the chance of precipitation alone is usually small. If the production process is not up to standard, the aluminum foil contains a lot of heavy metal elements, which may theoretically be precipitated after continuous high-temperature heating.
Studies have found that aluminum can damage brain cells and cause memory loss after being absorbed excessively in the human body. This poisoning process is difficult to detect and is time-consuming and long-lasting. However, the contact point of aluminum is 660 degrees Celsius, so the risk of being precipitated during barbecue is relatively small. Aluminum can not only transfer heat, but also prevent the meat from direct contact with the flame, which is equivalent to wearing a layer of "fire insulation". clothes" thereby reducing the chance of being scorched.
