One day.
Bottled mineral water can only be stored for one day after it is opened, which is basically its best drinking time. Of course, this does not mean that the shelf life of bottled mineral water is actually only one day. What I mean here is that there are bacteria in the mouth and air, which are polluted after opening the lid and can't be drunk for a long time.
After drinking, it can usually be stored for a long time, even if the bottle cap is tightened or left idle for too long, just like the shelf life written on it.
1.5 liters of water for a few days.
1.5 liters of water can be stored at room temperature for 2-3 days after opening the bottle, and it can be stored in the refrigerator for about a week. When the lid is opened, bacteria in the air will enter the water with bubbles. There are about 5000 bacteria in one cubic meter of air. After a long time, bacteria will multiply and grow, affecting the hygiene of drinking water. Therefore, unsealed water should be drunk as soon as possible, not left for a long time.
Mineral water is unpolluted underground mineral water that naturally gushes out from deep underground or is exposed artificially. Contains a certain amount of mineral salts, trace elements or carbon dioxide gas; In general, its chemical composition, flow rate, water temperature and other dynamics are relatively stable within the natural fluctuation range. Because water contains a certain number of special chemical components, organic substances and gases, or has a high temperature, it can affect the physiological functions of the human body. Mineral water is formed in deep circulation, containing minerals and limited indicators stipulated by national standards.
How long can 5L Nongfu Spring last after opening the bottle?
1. Nongfu Spring can be drunk within 2 hours after opening the bottle. The 5L natural water from Nongfu Spring should be poured into a glass for drinking. After dumping, the remaining water should be sealed with a cover immediately to prevent air contact.
2. There are more than 1000 kinds of bacteria in human mouth. Through the contact between the mouth and the bottle mouth, the unfinished mineral water will start to breed bacteria after drinking for 3 hours in Kaifeng. The number of colonies cultured in each milliliter of mineral water can reach 10000 after 24 hours storage. This is, you see, this clean mineral water is no longer suitable for drinking. Drinking this mineral water often can cause abdominal pain, diarrhea and other symptoms, which is harmful to the body.
How long will it take to finish the bottled water?
Unopened bottled water can be stored for about three months, and the shelf life of unopened bottled water is only about 15 days. It is best to drink it within one week, so as to ensure the quality of water. Water is the source of life and an indispensable drinking product in life. Both families and companies use bottled water. The bottled water just bought is sealed, which can prevent bacteria from entering the barrel and affect the water quality. After bottled water is opened, the water comes into contact with the air, which is easy to breed bacteria during use. Due to the structural defects of bottled water, once it is opened, microorganisms and dust in the air will enter the soup from the entrance, thus causing drinking water pollution. If bottled water is left open for too long, the taste will not change, but the water inside will contain a lot of bacteria. Expired bottled water can't be drunk: after bottled water comes into contact with various microorganisms in the air, bacteria will inevitably produce and then breed in the water. After the shelf life, water is easy to deteriorate; Especially some good bottled water, because there are many nutrients, bacteria are more likely to breed. If you are exposed to the air for a long time, it will go bad more easily, and people will have diarrhea after drinking it.
Note: Many people don't finish drinking bottled water before going out, and continue to drink it after half a month or more. Some people may think it's okay, but it's actually wrong. Drinking this water is harmful to their health; In addition, there are few people in the family, and some people drink a bucket of water for a month, which is also wrong. You'd better finish drinking bottled water within half a month, otherwise you don't know why you have diarrhea.
Obviously, unopened or unsealed bottled water can't be drunk after it expires, but it's too wasteful to dump it directly, so everyone can wash it, which is cleaner than tap water; In addition, expired bottled water can also be used for cooking. High temperature will kill many bacteria in water, making it healthier and more delicious to cook.
Five liters of bottled water can last for several days.
