How long does the barreled pure water have a shelf life?

Most of the drinking water used today is pure water, bottled and bottled water. Everyone knows that the things that are imported have a shelf life. After the bottled water is opened, it is impossible to use it at any time. If you leave it for a long time, can you drink it? How long is the shelf life of pure water ? Let me give you a brief introduction.

How long does the barreled pure water have a shelf life :

The shelf life of bottled purified water sold in the market is generally unopened for 3 months, and there is also a small amount of pure water with a shelf life of only one month, so large-capacity bottled purified water is easy to expire. The shelf life of bottled pure water is generally 1-2 years.

Shelf life after bottled water is opened:

Bottled water is exposed to bacteria after opening, causing pollution. These bacteria are mainly derived from hands, cups, water dispensers, etc. If the hand touches the seal of the bottled water, it is easy to leave the bacteria on the barrel; if the cup is not cleaned regularly, the bacteria will remain; the water dispenser is the most prone to bacteria, because the impurities in the bottled water, Minerals will settle in the inner tank of the water dispenser. Over time, it will seriously affect the quality of drinking water.

The shelf life of the opened bottled water is only 15 days, and the best time to drink is 5-7 days. If the bottled water in Kaifeng is left for more than half a month, although the taste does not change, the bacteria have exceeded the standard. Therefore, the time we drink bottled water should not be too long. If you haven't finished drinking for more than 15 days, don't drink any more water. Do other treatments and don't waste.

Other water shelf life

The shelf life of boiled water: only about 1 day. The one day mentioned here refers to the water filled in the thermos. The cool white is only about 16 hours.

Pure water shelf life: Generally, pure water is not contained in bacteria when it is packaged, but it will cause pollution to pure water when it is opened twice. Therefore, if pure water is more than 5 days, it is best to drink it after heating.

Mineral water shelf life: Unopened mineral water has a shelf life of about one year, but only about 5 days after the opening of the shelf life, but because the mineral water contains a lot of minerals, can not be heated, otherwise it will cause mineral precipitation, loss of its health effects . Therefore, after more than 5 days after opening the mineral water, it is not suitable for drinking.

Seeing this, everyone should know how long the shelf life of pure water depends on the situation. Therefore, everyone should pay attention to the fact that water can't be drunk, so be sure to drink healthy water.
