Into the summer, the temperature continues to rise, insulated bottles have become a must-have product for many people. But friends who like to use insulated bottles should pay attention, because if you are not careful, they may turn into “bombs” in your hand!
Good bottles, why do dried fruits explode after being soaked in hot water? Which drinks are not suitable to put in the bottles? How should we choose qualified and healthy insulated bottles? Today Gladerlife is here to talk to you about the insulated bottles.
- Why does soaking dried fruit in insulated bottles cause an explosion?
- The explosion of insulated bottles: most of them are caused by microorganisms
In fact, the explosion occurred when the dried fruit was soaked in hot water in the insulated bottles, which was caused by excessive gas production by microbial fermentation.
Ordinary bottles have many hygienic corners. For example, there may be a lot of bacteria hidden in the liner and the gaps in the bottle cap. Dried fruits are rich in nutrients, and the sugar and other components in them are dissolved after soaking in water, making them easier to be used by microorganisms. Therefore, in an environment with suitable temperature and sufficient nutrients, these microorganisms will ferment and produce a large amount of carbon dioxide and other gases, and the longer the time, the more gas will be produced; the air pressure in the airtight thermos cup will continue to increase. It may cause hot water to gush out and cause an “explosion” to hurt people.
- In addition to dried fruits, these foods also have the risk of explosion
After the above analysis, we can know that the food that is rich in nutrients and suitable for microbial reproduction is an important factor that causes the explosion if it is placed in the thermos cup for a long time. Therefore, in addition to dried fruits, high-sugar and high-nutrition foods such as fruit juice and milk tea, it is best to drink them immediately instead of keeping them in a thermos for a long time.
In addition, when drugs such as effervescent tablets come into contact with water, they will release a large amount of carbon dioxide quickly, and carbonated drinks themselves contain a lot of gas. This kind of food will cause the air pressure in the cup to increase. If it is shaken, it may cause the cup to burst, so it is best not to use insulated bottles for brewing or storage.
【Tips
(1) When using insulated bottles and other bottles with good airtightness, it is best to preheat them with hot water first, then pour them out, and then add hot water, so as not to cause a sudden increase in air pressure due to excessive temperature difference, causing hot water to “spout”.
(2) No matter what kind of hot drink is brewed with insulated bottles, it should not be kept for a long time; it is best not to unscrew the lid of the cup before drinking, and the gas can be released by carefully opening and closing the lid repeatedly, and the mouth of the cup should not face people when opening , to prevent injury. 】
- It is best not to put these drinks in insulated bottles!
Since insulated bottles have outstanding heat preservation function and good airtightness, many people not only use them to hold ice water, but also use them to make tea and hold milk and soy milk. Is this possible?
Using insulated bottles to pack these two types of drinks, although there is no risk of explosion, may affect the nutrition and taste of the drinks, and even shorten the service life of the insulated bottles!
- Insulated bottles to make tea: loss of nutrients
Tea contains nutrients such as tea polyphenols, tea polysaccharides, and caffeine, which have strong health care effects. When hot water is used to make tea in a teapot or an ordinary glass, the active substances and flavor substances in the tea will dissolve quickly, making the tea fragrant and sweet.
However, if you use a thermos cup to make tea, it is equivalent to continuously decocting tea leaves with high-temperature water, which will destroy the active substances and aromatic substances in the tea leaves due to overheating, resulting in nutrient loss, thick tea soup, dark color, and bitter taste.
- Milk and soy milk in a thermos cup: easy to go rancid
High-protein drinks such as milk and soy milk are best stored in a sterilized or low-temperature environment. If it is placed in a thermos cup for a long time after heating, the microorganisms in it will easily multiply, causing milk and soy milk to become rancid, and even produce flocs. After drinking, it is easy to cause abdominal pain, diarrhea and other gastrointestinal symptoms.
In addition, milk contains acidic substances such as lactose, amino acids, and fatty acids. If it is stored in a thermos cup for a long time, it may chemically react with the inner wall of the thermos cup and cause some alloying elements to dissolve.
【Tips:
Try not to use thermos cups to hold hot milk, soy milk and other drinks, and don’t leave them for too long, and it’s best to drink them within 3 hours. 】
