The mineral water is difficult to freeze
Xia Ri is hot, people like drinking the cold drink, retailer sells the mineral water after often freezing the bottled mineral water. Therefore often precipitate the problem and send back goods to the manufacturer.
The production of this phenomenon is because the supersaturated condition of calcium, magnesium appears in the icy course in the mineral water, and is up to the resolving of heavy carbonate, and produced the white sediment, especially to having high calcium, magnesium content, mineralization is greater than the mineral water of 400mg/L, will precipitate white slice or particle even more after freezing. The analysis data of the laboratory prove this too, is analyzed and compares with the original water after freezing many kinds of mineral water, because of producing white sediment, determine water after freezing. Among them heavy carbonate and calcium ion is obviously reduced, but other compositions in water after freezing, especially beneficials microelements to human body contain rich amount ofed in mineral water, such as leaning towards silicic acid, strontium,etc., there is no obvious change, so the mineral water after freezing has no harm to the human body to drink, to those greedy and cool persons, it is harmless to wish to drink the frozen water too. But there is precipitate, the sense organ index of influence, so mineral water national standard (GB8537- 1995) in the bottled water after all " until zero degrees Centigrade transport and store as follows bottled mineral water, regulation of China, there must be measure of preventing frostbite " .
