In what conditions to store boiled water. Storage of drinking water: how to maintain its useful properties in which capacity to store water

At first glance of any person, there is nothing easier than water! But at the same time, it is the most complex liquid: without having a taste, no smell, has a huge complex of useful qualities, in the absence of which no living organism survive.

Everyone food Product It has its own shelf life depending on many factors. There is naturally such a term and water. Let's see how to properly store water to her beneficial features remained as long as possible. To begin with, you need to make sure that the water itself. It is also important that the factor remains in which conditions and in what package the useful properties of water will be maintained, if possible, a longer period.

Water good quality In Kiev, first of all, should be clean. Therefore, it should not be chlorine and various additional substances. As for the container, you can offer several of its water storage types: plastic, glass, clay, metal and other vessels. It all depends on the quality of the water itself.

Drinking water storage container

IN lately It became very popular for water storage to use a plastic or metal container, which is subject to special processing before applying. A small amount of liquid from twenty to fifty liters can be stored in conventional plastic capacities with covers. At the same time, do not forget that the temperature during storage should not be more than twenty-five degrees. It is desirable that the containers do not fall under direct solar effect. When purchased water is used, then its storage will be specified on the container. If you comply with all these recommendations, it will definitely save your useful qualities throughout the specified period.

We advise you not to store water in a container from melamine. Even in appearance it seems attractive and durable, but melamine, as shown scientific research, It distinguishes harmful substances. And therefore, such water is capable of bringing harm to your body, and in some cases it can activate the actions of cancer cells.

Polyethylene and polyethylene terephthalate (PE and PET) are considered the most safe water storage materials. And one of the most dangerous - BES (Bisphenol a), which causes violations in the work of the endocrine system. Remember also that PVC (polyvinyl chloride) highlights harmful toxic substances. And what is very important, please note: it is impossible to categorically use such a container again.

You always need to know that water during long-term storage reduces its qualitative characteristics. Therefore, its storage time in glass containers ranges from two to three years, and in plastic - from three months of one year. Any carbonated water, as well as mineral, have a short shelf life.

Water in large polycarbonate bottles from nineteen to twenty-five liters retains its useful properties throughout the year. The material from which the containers are made, even during reuse, does not harm human health. But it should be remembered that only water is stored in such a container. Polycarbonate easily absorbs odors, and, accordingly, any other product will change its useful structure in such a container.

If you spend water in large quantities, then it is best in Kiev to order it through the site.

In the question of long-term storage drinking water Two patterns are clearly visible. We began to take care more about proper nutrition and the use of high-quality drinking water, and the living conditions in the big city just make it do.

Now few of the citizens will risk drinking water from the crane, and use it without cleaning for cooking even scary. From here in the go - the use of all sorts of home filters, the purchase of high-quality drinking water in supermarkets and stores, and the need for stocks and storage of water at home.

In addition, residents of cities are, of course visit public holiday destinations: cafes, dining rooms, restaurants, where the need for clean drinking water is no less. But here visitors have to take on faith that for the preparation of the first dishes, and sometimes second or numerous berry beverages use clean drinking water.

And how serious is the problem of storage?

Let's think ... at home clean drinking water should always. In addition to quenching thirst, cooking, the right and healthy "drain" children can be remembered and something else. Say, movement in the city in the city in summer without a driver - not always and joy.

Traveling distant and relatives ... Trips to the cottage, to the river, just on holiday without a bottle of water will not cost any way. And if 3-4 people go to such a journey? That's right, the number of liquid liters should be greater. And if it's a trip by car in the southern edges, when it is not known what will be in roadside stores. Of course, it is better to travel with your proven water reserves.

In general, how fun sang in one beautiful Soviet comedy film: "Because without water - and not there, and not here!" And this can not disagree.

Proper storage

For long and proper storage of drinking water, it is necessary to perform conditions related to lighting, temperature ambient and tarah (or capacity).

Ideal storage conditions it is:

• darkened place;
• temperature from 15 - 25 c?;
• glass or aluminum container.

But, agreed to keep water or take it with you in a glassware - very uncomfortable (hard and volumes are small). And the yield seems to be wide and massively using plastic containers (bottles, bottles and bottles).

Storage in plastic

The containers in which the water will be stored must be made of edible plastic. On a label of such a bottle, PET marking (polyethylene terephthalate - plastic is not dangerous for humans). There is also a PVC marking (PVC). - This is a material with toxic properties. For the storage of detergents of tanks, they are suitable for drinking water.

Capacity from melamine, white dense plastic - are categorically not suitable for storing drinking water. Their purpose is the storage of technical fluids. Such containers visually recognizable (especially motorists) and when tapping, they make a deaf low sound.

If there is no information on a plastic bottle about what material it is made, all this can be checked. It is enough to press and hold a nail over the surface, the PET bottle will be restored, a characteristic white trail will remain on PVC-container.

Additional storage conditions

Drinking water often gets to us from the store, which means you need to carefully read the label and pay attention to the following:

• method of preservation. Them are three: with antibiotic, gasing, ozonation. 1st well increases the shelf life, but this water can destroy human immunity. Two others are harmless, but after opening the container, water should be used for several days;
• spill time. Than it is closer, the more preserved in the water of the useful substances;
• place of spill. It is better if the water is harvested in your area, and the path to the store is not far away, and in storage time is good.

In general, drinking water in stores in sealed containers, in the correct conditions (dark place, temperature 15-25 c?) It may be from 6 to 12 months without loss of useful properties. If you approach the storage of drinking water with all seriousness, it is necessary to remember that after the "shop" capacity is printed and the entire liquid is used, to use the same capacity to re-storing water - not very desirable. Since even PET containers, in about a week begin to saturate water with a harmful substance: vinyl chloride. So, it will be more correct to use plastic bottles of one-time or as containers for short-term storage of drinking water. It is better to refer to proven suppliers, for example, you can order water to the office in the company Raska Jerelo - quality there at a good level.

Let's summarize

In plastic containers, drinking water can be stored for up to 12 months, provided that the spill and packaging were made in the factory. In order for the liquid to save its properties, it is necessary to observe the storage conditions (blasting, and temperature).

At home, keep drinking water in the "plastic" is permissible only briefly (up to 10 days). In travels for water reserves, plastic bottles will be suitable, but, let's say, in a week, it is necessary to get rid of such a container. For long-term storage of water, it is necessary to use glass dishes.

If you pour it into poor-quality containers, pollution or harmful chemical substances From the bottle. Water can not only purchase nasty smell And taste, but also to become dangerous to health.

Many doctors and nutritionists categorically declare that buying drinking water should only be in glass containers. All arguments are reduced to the fact that, entering into a reaction with water, plastic immediately begins to highlight harmful substances.

On the one hand, yes, the glass is the safest tair, it does not react with water, even if the bottle is very heated. On the other - it is absolutely not suitable for the carriage of water in 19l bottle.

The ideal material in this case is polycarbonate. And then questions arise about Besfenol A and the usual PET - is there any difference?

Let's figure out:

Ecology and hygiene conducted an examination and found out that cold water Besfenol and does not go;

To befenol and damage the body, a person must eat every day and drink at least 600kg food and water that has come into contact with polycarbonate;

In compliance with the rules and norms of bottling, storage and transportation, no harm does not carry a polycarbonate bottle and does not change its natural composition;

Polycarbonate has a high heat resistance (washing at a temperature of more than 60 degrees, which complies with EWBA recommendations);

It is suitable for recycling;

Pat in this regard greatly loses:

PET - the most unsafe for health containers: passes light and air, with severe heating can be distinguished harmful substances into water;

Maximum temperatures when washing 50 mods, which does not comply with EWBA requirements;

No disposal paths.

CONCLUSIONS

The safest package for water is glass. The glass does not react with water, and harmful substances from the glass container do not fall into the water, even if the bottle is heated. The shortcomings of glass are obvious - it is heavy and fragile.

In second place in safety - polycarbonate. This is the perfect packaging for large 18-19 liter bottles - the glasses is easier and is much stronger.

The most unsafe for the health of the water container - polyethylene terephthalate and polyvinyl chloride. These materials are missing light and air, and plastic bottles when heated can be released toxic substances into water, they are not recommended reused.

How to choose safe and high-quality bottled water?

Andrei Mosov, Head of the expert direction of NP "Roskontrol", doctor:

"Bottled water is the same product as everyone else, and it has a shelf life and should be stored under certain conditions. Read the label and follow the instructions. Regardless of the container, the water should not be stored in the sun. Especially dangerous sun rays and raising the temperature for water in plastic bottles - Toxic substances can fall into water. Choose water made recently. The longer the water was stored, the more harmful substances from the plastic in it had time to get. "
