1, water source and composition, mineral water: mineral water is spring water that naturally gushes from deep underground or is obtained through artificial mining. It contains many minerals and trace elements, such as calcium, magnesium, sodium and potassium. These minerals and trace elements play an important role in human metabolism and health. Purified water: Purified water is drinking water that is obtained from tap water or other water sources through physical methods such as filtration and disinfection. It contains almost no minerals and trace elements, so it has a low mineral content.
2, taste and appearance, mineral water: the taste of mineral water is usually refreshing, and some varieties may have a slight salty or bubbly taste. Its color may vary according to the types and contents of minerals and trace elements, ranging from transparent to light yellow or light brown. Pure water: the taste of pure water is relatively dull, close to tasteless. Its color is usually transparent or light yellow, which is not obviously different from other drinking water.
