Water in a plastic bottle should be stored at room temperature, in a dark place. A closed water bottle can be stored for up to a year, and an open one for no more than ten days. The plastic of the bottle must comply with the PET class.
Pick your recipe
Today on the shelves you can see more and more plastic water bottles, and at the porches there are many announcements about the delivery of bottled water. Distribution networks are happy to take water in plastic containers for sale, as it has a long shelf life.
Under normal conditions, water begins to change under the influence of light and heat, and after some time, bacteria that have fallen into the water give it an unpleasant smell and taste. But how is water stored in supermarkets? The fact is that manufacturers preserve all water in plastic bottles.
There are several ways to preserve:
• Adding an antibiotic;
• carbonation;
• Ozonation.
Water preserved in the first way can be stored for a very long time. But having antibiotics can harm your health and lower your immunity.
Carbonation and ozonation are harmless preservation methods, but such water will be stored until the bottle is opened. Therefore, after you unpack the bottle, you need to drink this water for several days.
How to store water in a plastic bottle
If you buy bottled water, for its storage you need to allocate a dark place in the kitchen or in the pantry. The optimum temperature for storing water is 15-30 degrees Celsius. Keep that water which was recently bottled and produced in your area - it stores more nutrients. Pay special attention to the plastic from which the bottle for storing water is made.
In which plastic bottle do you need to store water
The container in which water is stored must be made of food-grade plastic. The package must have a PET mark, such bottles are made from a substance called polyethylene terephthalate, it does not react with water and is safe for human health. Never store water in a bottle labeled with PVC. The material from which it is made has toxic properties. Do not store bottled water from melamine.
If there is no information on the bottle, then there is an easy way to check which class it belongs to. You need to press a nail on one of the sections of the bottle. A whitish “scar” will appear on PVC plastic, and PET containers will remain unchanged. You can recognize the melamine container by tapping it lightly - the sound will be dull.
