Water that naturally runs out from deep underground or is collected through well drilling, contains a certain amount of minerals, microelements or other compositions, is not contaminated in a certain area and has been protected against contamination; generally, its dynamic indexes, such as chemical compositions, flow and water temperature are relatively stable within the natural periodical fluctuation range.
2.1.1 Carbonated natural mineral water
natural mineral water with visible isogenous carbon dioxide releasing and generating bubbles naturally at normal temperature and pressure after packaging, where the unstable components may be removed by aeration, decantation, filtering or other methods and it is allowed to recycle and fill isogenous carbon dioxide, without changing the basic characteristics and main component content of the source water of natural mineral water.
