Aluminum poison in cans is stronger than that in bottles of drinks. Experts remind parents not to let their children drink too much cans. On the 11th of last month, "40% of aluminum in food exceeds the standard" once reported by CCTV, it immediately caused strong repercussions in the industry. In this regard, experts are even more exposed to the insider - the aluminum content of canned drinks is 3 to 5 times higher than that of bottled drinks, and warn parents to avoid letting children drink too many cans

the aluminum content in cans is five times higher than that in bottles.

there are a variety of packaging materials for beverages, mainly paper, bottled, cans, bags, etc. According to the investigation of 22 kinds of drinks by researchers, the aluminum content in cans is higher, which is 3 to 6 times higher than that in bottled drinks. Recently, the China Center for Disease Control and Prevention released a monitoring report on the dietary structure of Chinese residents. The results showed that the aluminum content of 40% of food exceeded the national standard by 2 to 9 times, and the aluminum content of canned beverages was 3 to 5 times higher than that of bottled beverages

why is the aluminum content in cans high? According to the analysis of insiders, cans are made of aluminum alloy, and their inner walls are coated with some organic paint, which isolates the aluminum alloy from beverages. In the process of processing, it is inevitable that the protective coating is not applied in some places, or it is too thin, which causes the aluminum alloy on the inner wall of the tank to contact with the beverage. Over time, aluminum gradually dissolves, especially when acidic or alkaline drinks are contained in the cans

children's daily intake of aluminum exceeds the standard

it is reported that after years of research, scientists have found that aluminum is absorbed by the human body, deposited in the brain, heart, liver, kidney and other organs of the human body, and excreted slowly, which will cause great harm to the functions of various organs, especially brain tissue and immune function. In 1989, the World Health Organization officially identified aluminum as a food pollutant to be controlled, and proposed that the allowable daily intake of aluminum for adults is 60 mg. Specifically, the allowable daily intake of aluminum per kilogram of body weight should not exceed 1 mg

according to the survey from the China Center for Disease Control and prevention, the average daily intake of aluminum by Chinese residents is 34 mg, which is relatively safe for adults, but this amount has exceeded children's tolerance, which will seriously affect intellectual development

As early as the middle of last month, Tianjin municipal health law enforcement department seized nearly 1600 boxes of almond dew reloaded with waste cans at a Xiyangyang wholesale Station in Ji county. After further investigation, it was found that the recycled cans were only renovated with a sink and several bags of washing powder. It is understood that the wholesale price of this almond juice produced by Zunhua Hongxing and Huaao beverage factory is very cheap because it is packed in old cans. The purchase price of Lulu produced in Chengde is 44.5 yuan per box, while that of hongxinghe Huaao beverage factory is 15 yuan per box

due to the reuse of cans, food packaging regulations lack corresponding constraints. In this regard, the Tianjin Health Bureau asked the Ministry of health to put forward handling opinions. The Ministry of health made it clear in its reply to the Tianjin Health Bureau that no unit or individual is allowed to use recycled scrap metal cans to fill food and beverage for sale. However, according to insiders, since there are no special regulations to regulate, the cost difference between the first-time use of cans and the secondary use of cans is as much as seven times. The phenomenon of secondary use of cans is very common in some small workshop enterprises

30% of extruded food aluminum exceeds the standard

consumers recognize the "QS" mark when buying

according to CCTV reports, the school of food science and technology of China Agricultural University recently organized a special teaching experiment on extruded food, in which 20 kinds of extruded food were randomly selected. The product range will affect the service life of the device, covering the main production areas of extruded food such as Fujian, Shanghai and Tianjin. The experimenters compared the results of the aluminum residue in puffed food obtained in the experiment with the relevant national standards, and found that among the 20 samples tested, the aluminum residue in 7 samples exceeded the provisions of the national standards. Products that exceed the standard include shrimp sticks, cheese sticks, tornadoes, pea crisps and other mainstream puffed foods in the market. Eating extruded food with excessive aluminum will continuously accumulate in the human body, cause nervous system diseases, interfere with people's thinking, consciousness and memory function of strange materials that change the world, and even lead to dementia in severe cases

quality inspection experts said that at present, there are many brands of puffed food and fried snacks on the market, and the product quality is also mixed. As puffed food and fried snacks are generally characterized by high fat, high calorie, high salt, high sugar, high monosodium glutamate and so on, their nutritional components are not comprehensive. Fat, carbohydrate and protein are the main components, and they all belong to low crude fiber food. Long term consumption of such food in large quantities, if the intake of crude fiber is insufficient and the amount of exercise is not very large, it is easy to cause fat accumulation in the human body; Children are in the stage of physical development. If they eat a lot of such food before meals, it is easy to cause a sense of fullness, which affects their normal meals, resulting in malnutrition. Puffed food has been included in the scope of food quality and safety production license management. Consumers should choose products with "QS" logo and pay attention to the brand
