The national standard of "Drinking Natural Mineral Water" was formed in 1995, in which the total number of colonies of the filled product is required to be less than 5 units per milliliter.

The nine boundary indicators specified in the national standard include lithium, strontium, zinc, selenium, bromide, iodide, metasilicic acid, free carbon dioxide, and total dissolved solids.

Standards: 1. Unpolluted underground mineral water that naturally gushes out of the depths of the underground or is artificially revealed; 2. Contains a certain amount of mineral salts, trace elements and carbon dioxide gas; 3. The dynamics of chemical composition, flow rate, water temperature and so on are relatively stable within the natural fluctuation range; 4. The limit indicators of lithium, strontium, zinc, bromide, iodide, metasilicic acid, selenium, free carbon dioxide and total dissolved solids are qualified.

With the development of China's economy and society and the improvement of people's living standards, people's brand awareness of consumption is getting stronger and stronger. Attaching importance to the brand reflects the change in the consumer's life concept. With the continuous improvement of production equipment and technology level, mineral water products are becoming more and more homogeneous today, the physical properties of the products are not much different, and only the brand with profound connotation can give consumers spiritual sustenance.

Mineral water of the same quality and price, consumers prefer branded products.

When the development of the commodity economy reaches a certain stage, enterprise competition no longer stays at price reduction, but competition at the brand level. Establish a famous brand, you will grasp the initiative to occupy the market. In the future competition of mineral water enterprises, enterprises without brands or weak brands will become OEM processing plants with strong brands, losing their own terminal market and the foundation of competition.

Summary. Hello dear, happy to answer your <>

Drinking water mineral standard iron does not exceed manganese, no copper, no more sulfate, no more than 250mg L, total hardness (based on CaCO3, not more than 450mg L.).

What is the standard for minerals in drinking water?

Hello dear, I'm glad to answer your <>

Drinking water mineral standard iron does not exceed manganese, no copper, no more than sulfate, no more than 250mg L, the general bureau is hard to travel to the state (in terms of CaCO3, not more than 450mg L.).

Mineral water is generally made from urban tap water as raw water, and then filled after pure purification processing, adding minerals, and hidden sterilization treatment. The types of material water added to the mineral trousers are relatively wild and simple, and there is no unified national standard for quality.
