Aluminum was once used to make cooking utensils, and very popular, because aluminum pots and other rust, aluminum and oxygen in the air will react to form a dense layer of aluminum oxide coatings on aluminum products processing price, but aluminum products processing, scientific evidence aluminum tableware is not suitable for cooking or prolonged storage of acidic, alkaline and salty foods, because acid salt, etc. can be directly etched aluminum surface of the protective film and aluminum products themselves. The study found that the aluminum elements can damage a person's brain cells. According to the assessment of the World Health Organization, the daily intake of aluminum is specified 0 ~ 0.6mg / kg, where kg refers to a person's weight, that is, a 60kg human intake of 36mg. China's "food additive standard GB2760-2011" set forth in aluminum products processing factories, the residual amount of aluminum is less than or equal to 100mg / kg. Of aluminum in the human body is slowly accumulates, toxicity which causes the slow and difficult to detect, but aluminum products processing machinery, once metabolic disorders toxicity occurs, the consequences are very serious. Therefore, we must draw our attention, in their daily lives to prevent the absorption of aluminum, reducing the use of aluminum products. Therefore aluminum cookware has been gradually phased out.
