Mineral water, purified water, mountain spring water, mineral water. ① Mineral water: it is unpolluted mineral water (containing a certain amount of minerals, trace elements or carbon dioxide gas, and its chemical composition, flow rate, water temperature and other dynamics are relatively stable within the natural fluctuation range) that naturally gushes out from deep underground or is exposed artificially. It is a valuable mineral resource and natural drink, and the minerals and trace elements contained in it have health care and nutrition effects on human health. ② Pure water: the drinking water obtained after artificial treatment is made by removing minerals, organic components, harmful substances and microorganisms from water by distillation, ion exchange and reverse osmosis. Its biggest feature is that it does not contain any beneficial minerals and harmful impurities. Whether it has an impact on human health has always been a controversial topic among experts. ③ Mountain spring water: It is a kind of natural drinking water, which contains certain minerals and trace elements, but it can't meet the requirements of mineral water. There is no national standard for mountain spring water, and the product quality is mainly controlled by production enterprises according to enterprise standards. ④ Mineral water: It is made of pure water and contains a small amount of mineralized elements. This kind of water is developed in view of the assertion that drinking purified water for a long time is harmful to human health. At present, there is no unified standard for this product in China, and enterprises make their own standards to control it. Some enterprises use mineral concentrated solution to prepare, and some enterprises add chemical reagents to water. The safety and effectiveness of these additives have not been demonstrated, and their contents have no scientific basis.
Since purified water entered the market in China, what water to drink has become the focus of debate in the industry, and it is also a topic that consumers are very concerned about. After several years of heated debate, the conclusion is: drink healthy water when drinking water. All water that meets the standard of healthy drinking water is healthy water; Mineral water is an ideal healthy drink. The proportion of some minerals and trace elements needed by human body in mineral water is basically the same as that of human body, which is in ionic state and easy to be absorbed by human body. Chen Mengxiong, a senior academician of Chinese Academy of Sciences, pointed out that natural spring water is better than pure water, and mineral water is better than natural spring water. Mineral water has the characteristics of health care, nutrition and low calorie, and is known as the first drink in the world.
