Many people use thermos cups as ordinary cups. They drink hot water, make tea and even take drinks without changing cups. But the material of the thermos cup is different from that of the ordinary cup after all. If you don't pay attention to their use, it will affect your health.
I remember a thermos cup exploded in the news before. The party soaked red dates in a thermos cup, but always forgot to drink them. After more than ten days of driving, the eyeball was injured by the lid of the cup. It's really scary.
After investigating the cause of the explosion, it was learned that jujube soaked in water led to fungus reproduction. If it is stored in a sealed thermos cup for a long time, it will ferment to produce inflation gas, which will increase the air pressure in the cup and make it easy to explode if it is suddenly unscrewed. Therefore, not everything can be put in a thermos. Let's talk about the matters needing attention in the use of thermos cups.
Hot water bottles are not suitable for these three drinks:
1, not suitable for milk.
A cup of hot milk in the morning and evening is essential for the health of many friends, but it is better to drink milk directly in an ordinary cup. Don't pour it into the thermos cup, otherwise the microorganisms in the milk will multiply rapidly at a suitable temperature, which will lead to the deterioration of the milk and cause stomach pain. Hot milk should be finished as soon as possible.
2, it is not appropriate to make tea
Many people are used to making tea in thermos cups, but they don't know that the longer they soak, the less healthy they drink. Tea is suitable for brewing with about 80% water. If you use a thermos cup to make tea, it is easy to ferment under the condition of high temperature and constant temperature, and vitamins are destroyed in large quantities, which not only increases harmful substances, but also destroys the nutritional value of tea and affects the taste of tea.
3. Acidic drinks
We all know that stainless steel has poor corrosion resistance and is afraid of strong acid. If you hold acidic drinks for a long time, it may damage human health and its liner. In the same way, a large number of acidic substances are dissolved in the fried Chinese medicine, which is not suitable for putting a thermos cup.
In addition, fruit juice is not suitable for high temperature storage. The thermos cup is well sealed, and the juice with high sweetness is easy to breed a large number of microorganisms in the cup, leading to deterioration.
How to choose a qualified thermos cup;
Under normal circumstances, as long as you buy a regular brand of vacuum flask, the probability of problems is extremely low, so how should you choose a vacuum flask?
1, look at the liner. First of all, let's see if it is 304 stainless steel, which is recognized as food-grade stainless steel by the state. Then see if there are scratches on the surface of the inner container and feel whether the inside and outside of the cup are smooth or rough.
2. Look at this lid. All qualified inner covers are made of new food-grade materials, and there is no peculiar smell. Unscrew the lid of the cup. If unscrewing is better, the quality will pass. If you can't twist it from the beginning, or make a harsh sound, the lid of this thermos cup is easy to break, and there will be deflation and water leakage, and the insulation effect is not good.
3, see the manufacturer, adopt production standards, use precautions, and make sure it is not "three no products" before you can rest assured.
How to use the thermos correctly;
1. Before the new thermos cup is used, it must be disinfected with boiling water at high temperature.
2. Before using the thermos cup, it is recommended to scald it with hot water, and then continue to use it after pouring it out. This can improve the thermal insulation performance, and at the same time avoid the sudden increase of air pressure and the scalding of hot water caused by excessive temperature difference.
3. Avoid collision and collision during use, which will affect the thermal insulation effect.
4. After using the thermos cup every day, it should be thoroughly cleaned, and then the water stains in the cup should be fully dried, and then the cup cover should be covered to prevent the growth of bacteria.
Finally, Xiao Tian reminds everyone that in order to avoid burns, it is best to cool the boiling water before pouring it into the thermos cup.
