Mineral water is common in daily life, with a wide variety of types and varying prices. Many people choose it not only because it is hygienic and clean, but also because it is rich in minerals, which is beneficial to the body. So, can you drink mineral water that has been left in the sun?
Mineral water that has been left in the sun can be drunk.
Mineral water contains various mineral salts and trace elements. After being exposed to the sun, it will not produce harmful substances and is safe to drink. Even if the mineral water itself is heated by the sun and becomes hot, its quality will not change, and it can still be drunk. Mineral water bottles are now made of PVC and PET materials. After long-term exposure to the sun, these materials will release some organic substances that mix into the water, but they are not harmful to the human body. Therefore, mineral water that has been left in the sun can be continued to be consumed.
Why does mineral water left in the sun taste different?
PVC, or polyvinyl chloride, decomposes and produces hydrogen chloride when exposed to temperatures above 100°C or for long periods of sunlight. It easily dissolves in water, significantly increasing the water's acidity and changing its taste, but it does not affect the water's drinkability.
How long can mineral water left in the sun be stored?
Careful people all know that mineral water, although it is water, has a shelf life. Due to the softening of the bottle during exposure to the sun, some air and bacteria can enter the bottle, which will significantly shorten the shelf life of the mineral water. Therefore, mineral water that has been left in the sun is best consumed on the same day.
How to store mineral water in hot weather?
Indoors, mineral water can be stored in the refrigerator's refrigerator compartment. It is not only hygienic but can also be appropriately chilled to a suitable drinking temperature. Outdoors, due to the relatively high temperature, it is best to place mineral water in places where the sun cannot shine directly, such as under a tree or in a corner of a house, to avoid the softening of the mineral water bottle and to reduce the health and safety risks of the water.
Does mineral water need to be boiled?
Mineral water does not need to be boiled.
The main value of mineral water is to provide the drinker with a large amount of minerals. During the heating and boiling process, many oxidation and displacement reactions occur in the water. Especially the mineral elements in mineral water, such as selenium and zinc, which have oxidizing properties, are significantly reduced, which will significantly reduce the nutritional value of the mineral water. Therefore, it is not recommended to drink boiled mineral water.
