Many families drink bottled water. Experts suggest that, especially in the summer, bottled water is best served within a week after opening. Not only that, there is a special feature of bottled water, it is not suitable for fresh drinks, it is best to put it for 1-2 days before drinking, to achieve “broken seven ζ two”.
Therefore, Dong Jinshi, vice president of the International Food Packaging Association, reminded that the summer temperature is high and the growth rate of bacteria is greatly accelerated. The bottled water in Kaifeng is finished within one week, which can reduce the risk of bacterial invasion by the human body.
This is “seven” and it’s okay to understand, “ζδΊ” is a bit confusing. Because everyone thinks that the things that are in the mouth are always fresher and better. Is there anything special about this bottled water?
According to Dong Jinshi, many of the bottled water sold in the market will be disinfected with ozone before being filled. Ozone is a strong oxidant, so it reacts with minerals in the water to form bromate, which is harmful to humans. Studies have found that bromate has a carcinogenic effect on experimental animals, but the carcinogenic effect on the human body is not certain. Therefore, bromate is classified as a substance that may be carcinogenic to humans.
So don’t rush to unpack the bottled water after buying it, because you don’t know if it is freshly canned. The insurance method is to let the harmful substances such as bromate dissolved in water be decomposed into harmless bromide before drinking for a day or two.
