The National Food Safety Standard for Drinking Natural Mineral Water (GB 8537-2018) specifies seven limit indicators for natural mineral water, including lithium, strontium, zinc, metasilicic acid, selenium, free carbon dioxide, and total dissolved solids. Drinking natural mineral water should meet the requirements for one or more of these indicators.
When choosing drinking natural mineral water, we also need to pay attention to the label. In addition to indicating the product name, ingredient list, net content and specifications, the name, address and contact information of the producer and/or distributor, production date and shelf life, storage conditions, food production license number, and product standard code, the product label for natural mineral water should also indicate the following:
1. Source of the natural mineral water;
2. Limit indicators for product compliance and total dissolved solids;
3. Content range of major cations (K+, Na+, Ca2+, Mg2+);
4. When the fluoride content is greater than 1.0 mg/L, it should be labeled "Contains fluoride".
