Can you drink expired mineral water?

We all know that everything has a certain shelf life, but it is easy for people to overlook one thing. In fact, the water we drink also has a certain shelf life. Whether it is mineral water or boiled water, it has a certain shelf life. If it exceeds this period, it is very easy for there to be a lot of bacteria in it, which is not conducive to drinking.

We all know that water should be boiled before drinking so that the bacteria in it will die due to the high temperature. However, few people know that once the hot water is boiled, it begins a countdown to preserve the food. When boiling water is poured into a cup, bacteria will begin to grow, because when the water temperature is above 80 degrees Celsius, bacteria will not grow in the water, because water above 80 degrees also has a sterilization effect.

We all know that drinking a glass of cold boiled water is good for health, so many people like to pour water the night before so that they can drink it the next morning. However, they don’t know that this is not only unhealthy, but also easy to cause gastrointestinal diseases.

Boiled water stored in thermos bottles for a long time is prone to produce nitrite, which is carcinogenic. Therefore, its shelf life is only 1 day. If we look closely, we will find that there is a lot of scale in the thermos. These are calcium-magnesium compounds with a lot of heavy metals attached to them, which can cause harm to the human body. Therefore, hot water should not be stored in thermos.

Purified water is made by reverse osmosis, distillation, ion exchange and other methods to make the water pure, clean, and free of bacteria and impurities. But it also has a shelf life, which is only 5 days.

Generally, purified water does not contain bacteria when it is packaged, but opening it for the second time will cause contamination to the purified water, so if the purified water is more than 5 days old, it is best to heat it before drinking.

Especially for bottled mineral water, if you open the cap and drink it again, some bacteria will enter. So if you have drunk bottled mineral water for more than 3 days, try not to drink it again. Or if you have drunk it for more than 5 days, you should kill the bacteria in it if you want to drink it again. You can use heating method.
