I believe we have all heard some "health warnings". For example, the milk of aluminum bags will cause aluminum poisoning after heating, chewing gum will stick to the intestines, eating deafness will become dumb, etc. But are these true? ? Many people blindly believe but do not seek the truth. In recent days, the Beijing Science and Technology Association has conducted a professional analysis of such rumors and let experts tell you whether these things are true.
Many people have seen or heard such news, that is, aluminum packaging bags of milk poisoning, bagged milk heating and drinking milk will not only lead to loss of nutrients, but also the precipitation of heavy metal aluminum packaging, causing poisoning. Explain to this expert: Chemical technology, Yu Fang, vice president of the Science Department of Peking University, explained that a layer of aluminum foil is added inside the package of milk, although there is only a thin layer of aluminum foil and polyethylene film to separate the milk, but in the polyethylene film The melting point is usually 120 degrees Celsius, much higher than the maximum temperature of water, it can not be broken and melted in the boiling process, and it is less likely to separate heavy metal aluminum foil. As long as the bag's quality standards, there will generally be no problem of excessive aluminum poisoning.
Although the packaging bag has a layer of aluminum foil, it will not affect the quality of the milk after heating. Therefore, we should not listen to rumors, not to spread these rumors, so as to avoid biased beliefs, and spread rumors, causing social problems. influences.
