Does mineral water have an expiration date, and how long does mineral water have a shelf life

Yes. Generally, mineral water has a shelf life, which is one year for bottles and one month for barrels.

Bottled water should not be opened for more than a week, because the bottled water in the volume of water at the same time as the volume of bacteria in the air often into the water with bubbles, generally a cubic meter of air about 5000 bacteria (not pathogenic bacteria), a long time bacteria will multiply and grow and affect drinking water hygiene, so the water after opening should be drunk as soon as possible and should not be put for a long time.

After a week or five days, it is best to boil it again.

As for the mineral water or boiled tap water, there are no differences in geographical location.

Of course, mineral water is good in the city (mineral water is natural, different from pure water, but what I know seems to be Nongfu Spring is pure natural, and Master Kong and other mineral water seem to be artificially added with minerals needed by the human body, and my impression seems to be like this. ）。If it is in a polluted place such as a rural area or far away from an industrial area, it is better to boil tap water or well water.

Yes, the usual shelf life is 12 months. Because bottled water is sterilized; The water production is sterilized and ions removed by ultrafiltration equipment, the filling is a closed assembly line, the container is also externally managed, and finally sterilized by ultraviolet light and ozone, which is basically sterile, so it can be stored for a period of time, generally about 12 months. Ordinary water is exposed to the air and can quickly contaminate microorganisms.

The shelf life of mineral water is about one year.

There are many kinds of mineral water, generally divided into bottled water and bottled water, and it also has a shelf life, for unopened mineral water, the shelf life of bottled water is generally about 1 month, and bottled water is about 1 year, as long as it is unopened, its shelf life is relatively long.

For mineral water that has been opened, then its shelf life will not be long, bottled water because the bacteria in the volume air tend to enter the water with bubbles at the same time as the water is released, and it is more likely to be contaminated by bacteria, so the shelf life of bottled water is about 1 week. The shelf life of bottled water will be shorter, its packaging is relatively less tight, and it is in direct contact with the human mouth, so it is more susceptible to influence, and its shelf life is about 1-2 days.

Can you drink mineral water after its expiration date?

Can't drink it anymore. Mineral water cannot be drunk after the expiration date, regardless of whether it has deteriorated or not, it is not recommended to continue drinking. Although mineral water has a long shelf life, after the expiration date, it also means that it has been stored for a long time, and its contents are likely to change.

And because most of the mineral water is packed in plastic bottles, although the plastic itself is not toxic, there are also ingredients added when synthesizing plastic, and it is easy to precipitate at about 50 degrees. When the mineral water is not well preserved, it is prevented from sunlight or other factors for a long time, then harmful substances are easy to appear in the mineral water, which is not good for human health.

Bottled mineral water generally has a shelf life of 24 months. Mineral water is unpolluted underground mineral water that springs naturally from deep underground or is artificially exposed; 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 is formed by circulation in the deep stratum and contains minerals and limited indicators specified in national standards.

Summary. Hello, as long as the mineral water is unopened, not to mention that it can be shelved for 18 months without adding preservatives, even if it is shelf life for 500 years, it is possible. The reason why manufacturers indicate the shelf life of mineral water as 18 months is not the shelf life of mineral water, but the shelf life of the bottle.

As long as the mineral water is unopened, not to mention that it can be shelved for 18 months without adding preservatives, even if it is guaranteed for 500 years, it is possible to mess with Wang Sun. The reason why the manufacturer indicates the shelf life of mineral water as 18 months is not the shelf life of the mineral chain spring water, but the shelf life of the bottle.

Because most of the most advanced mineral water on the market is in plastic bottles, although the plastic itself is not toxic, but the ingredients added when synthesizing plastic are harmful to the human body, such as antimony element, as long as the temperature exceeds 50 degrees Celsius, this toxic element is easy to be precipitated. And over time, the possibility of toxic elements precipitation will also increase, so the 18-month shelf life indicated by the mineral water is very likely to be the shelf life of plastic bottles!

Summary. Food deterioration is generally due to the influence of external factors such as bacteria and light, under normal circumstances, the mineral water that has not been opened has a good seal, and there will be almost no bacterial invasion to destroy the water quality, and the mineral water that has just left the factory is also sterile water, so the shelf life of the mineral water itself is far more than one or two years written in the bottle. In fact, this shelf life is not the shelf life of mineral water, but the shelf life of the bottle.

Mineral water bottles are generally plastic bottles, and synthetic plastic substances may degrade and penetrate into mineral water from the bottle over time, such as the decomposition products of the polymer compound polyethylene terephthalate (PET), and the precipitation of antimony, an additive used to stabilize the plastic in the bottle, which may not only affect the taste of the water, but also be harmful to the human body, thus causing the mineral water to expire.

Okay, thanks

Mineral water has an expiration date. The shelf life of mineral water is generally 1 to 2 years, and the specific shelf life will be different according to the way the mineral water is destroyed, but generally speaking, it is more than one year, and you can look at the production date and shelf life when buying mineral water, and the period marked on the bottle shall prevail. However, it is also important to pay attention to the impact of environmental factors and mineral water bottles on water quality, and do not generalize.

Mineral water is a kind of underground mineral water that emerges naturally from the depths of the ground, or has been artificially exposed and has not been contaminated by the spike to the filthy group, and contains trace elements, mineral salts and other nutrients required by the human body. With the rapid economic and social development, people's living standards are also constantly improving, so there are certain requirements for the quality of mineral water.
