After the mineral water is opened, is it impossible to drink it after two days??

It's not that you can't drink it. Opened the can and nothing. The shelf life of water is not that bad.

Yes, air pollution.

Mineral water can be drunk two days after opening. After the bottle of rabies water is opened, bacteria will naturally appear after a period of contact with the air. But that doesn't mean bottled water can't be drunk anymore.

In fact, bacteria are just a general term, and they are divided into beneficial bacteria and harmful bacteria (i.e., pathogenic bacteria.

and bacteria that are neither beneficial nor harmless to the human body. In fact, it is only in extreme circumstances, such as the prevalence of epidemics, that pathogenic bacteria enter the bottled water through the air; Other times, airborne bacteria don't interfere with drinking bottled water.

I bought liters and drank for three days. Currently alive.

No, really! If you don't believe it, just smell it!

I don't know what you mean by opening your mouth is just opening your mouth, or opening your mouth, and if you want me to say it's better not to drink, after all, it's been two days, what do you think?

It is recommended not to drink it, because bottled water is generally sealed at a constant temperature to ensure its quality. Once opened, it will come into contact with various substances in the air, and it is easy to deteriorate, and drinking too much water for a few days is still not good for the body. Therefore, bottled drinks, water and other things are generally drunk out of the cap.

There are more than 1,000 kinds of bacteria in the human mouth, through the contact between the mouth and the bottle, the unfinished mineral water will begin to breed bacteria after three hours of drinking after opening, and the bacterial colonies cultivated in the mineral water after 24 hours can reach 10,000 per milliliter, and the mineral water that looks very clean is no longer suitable for drinking.

Drinking such mineral water regularly can cause abdominal pain, diarrhea and other symptoms, which can be harmful to your health.

After opening the bottle, mineral water cannot be drunk after one day in the summer and two days in the winter. Bottled mineral water should be drunk as soon as possible after opening the bottle, because bottled water does not contain chlorine, and there is no antibacterial effect.

1. Expiration date

Mineral water cannot be drunk after one day in summer and two days in winter. Mineral water does not contain antibacterial materials, the temperature is high in summer, bacteria are easy to multiply, after opening the bottle contact with the human mouth and air, 24 hours later, the bacteria in the bottle will exceed the standard, not suitable for drinking. In winter, the temperature is low, and the bacteria multiply slowly, but after 2 days, it is not suitable for drinking.

2. Expired use

Expired mineral water should not be poured out, water should be saved, and expired mineral water should be used wisely. If the bottle of water has not been opened for more than 2 days, it can be used after heating and boiling, it can be used for washing your face and brushing your teeth for more than 3 days, and it can be used for watering flowers, mopping the floor, wiping the table, etc.

3. Avoid exposure to the sun

Mineral water should not be consumed if it is left in the sun or after exposure to the sun in the car. Not only the shape of the mineral water bottle will be deformed, the plastic may also produce toxic substances after exposure, and the water that has been drunk has greatly increased the rate of bacterial reproduction because of the temperature increase of the exposure, and it is easy to deteriorate soon, so the mineral water should not be drunk after exposure.

Mineral water cannot be drunk for 48 hours after opening the bottle. After opening, mineral water should be drunk as soon as possible and should not be left for a long time. There are about 5,000 bacteria in one cubic meter of air, and over time bacteria will multiply and grow and affect drinking water hygiene.

Most of these minerals are found in the mineral springs themselves.

White precipitation:

When mineral water is heated or refrigerated, it produces a white precipitate the size of a needle's tip, called calcium carbonate, which is the same thing as the white powder formed by twisting calcium tablets. Deep in the formation, calcium is dissolved in mineral water at a temperature of around 19 degrees Celsius. The mineral water is pumped into the water treatment equipment through the deep well pump of the mineral water plant, and then filled and transported, the water temperature has changed, and the calcium has begun to precipitate.

If it is reheated or refrigerated, the precipitation of calcium increases, which is what we see as a white precipitate.

Redness of tea: Because tea contains a certain amount of protein, tannins, pectin, tea polyphenols and other components, they are complexed with calcium, magnesium, iron, etc. in mineral water to form turbidity and precipitate, which affects the turbidity of tea. The oxidation of iron ions in the water displaces the tannic acid and tea polyphenols of the tea, and converts the colorless carboxyl group into a colored carbon group, thereby deepening the color of the tea, which is tan, affecting the senses, but harmless.

More than 24 hours.

It is recommended to drink the mineral water within 1-2 hours after opening the lid. Mineral water that has been drunk for more than 24 hours cannot be drunk. Mineral water is a type of drinking water rich in minerals, trace elements or other substances, and is made from water gushing out of underground mineral springs.

Bowan mineral water is water that contains dissolved minerals or more gases. It is recommended to drink the mineral water within 1-2 hours after opening the lid, the mineral water is originally very few bacteria, but after drinking, the bacteria in the mouth will enter the water bottle, and the mineral water will begin to breed bacteria after drinking 3 hours, so try not to stay overnight, the longer the time, the more dust-rich bacteria in the mineral water, and the higher the risk to health.

It can only be left for a maximum of one day, and the mineral water after opening should be drunk as soon as possible. If it's summer, don't drink the mineral water that you haven't drunk that day, because bacteria grow very quickly in summer. Bacteria are everywhere, although the bottle cap will isolate some bacteria, but in the process of drinking mineral water, we will still leave bacteria on the bottle mouth, and these bacteria let them continue to breed, from Weiming to cause mineral water to deteriorate.

Mineral water is underground mineral water that springs naturally from deep underground or is artificially exposed and unpolluted; Contains a certain amount of mineral salts, trace elements or carbon dioxide gas; Under normal circumstances, its chemical composition, flow rate, water temperature and other dynamics are relatively stable within the natural fluctuation range.

Mineral water cannot be drunk for a day after the bottle is opened. The shelf life of unopened mineral water is generally about 12 months, but once the bottle is opened, it is generally recommended to drink the water within one day, after opening the bottle, the bacterial growth rate is very fast, the longer the time to open the mineral water, the more bacterial growth, so the faster you drink the healthier. In addition, the shelf life of bottled mineral water after opening the bottle is generally about 10 15 days, and the overall drinking time should not exceed this cycle.

How to judge whether mineral water is good or not.

1) Check the ingredients.

Mineral water that meets the standards has a clear product ingredient identification, which is also convenient for consumers to check the composition of mineral water, we focus on checking whether the content of calcium, magnesium, sodium and potassium 4 mineral elements meets the national standard.

2) Total TDS.

According to the international water quality judgment standard, if the total amount of TDS is 1000mg L, it is mineral water with high salinity; If the total amount of TDS is 1000mg L, it is a low salinity mineral water, which has a better taste.
