I found that as soon as winter comes, the use of thermos cups increases exponentially, because when the weather is cold, ordinary cups can be filled with water too quickly, and now young people pay attention to health preservation, the stem of "soaking wolfberries in thermos cups", It's not just talking.
Many people use thermos mugs as ordinary cups. They do not change the cups for drinking hot water, making tea or even holding beverages. However, the material of thermos mugs is different from ordinary mugs. If they are not used carefully, they will affect their health.
I remember that there was an explosion of a vacuum flask in the news before. The party used a vacuum flask to soak red dates, but I forgot to drink it. It took more than ten days to open it. The lid of the glass suddenly hurt my eyeballs. Terrible.
checked the cause of the explosion, and found that the red jujube soaked in water caused fungi to multiply. If stored in a sealed thermos cup for a long time, it will ferment and produce swelling gas, which will increase the air pressure in the cup. It is easy to unscrew it suddenly. explosion occurs. Therefore, not everything can be installed in a vacuum flask. Let me tell you what you need to pay attention to when using the vacuum flask.
The thermos cup is not suitable for these three kinds of drinks:
1, not suitable for milk
A cup of hot milk in the morning and evening is a health essential for many friends, but it is good to drink the milk directly or in an ordinary cup, do not pour it into a thermos. Otherwise, the microorganisms in the milk will multiply rapidly at a suitable temperature, causing the milk to deteriorate, causing stomach pain, etc. The sooner the heated milk is consumed, the better.
2, not suitable for making tea
Many people are used to making tea in a thermos, but they don’t know that the longer they make it, the more unhealthy they are to drink. Tea is suitable for brewing with water at around 80℃. If you use a thermos cup to make tea, the tea will be easy to ferment under the conditions of high temperature and constant temperature. Vitamins will be destroyed in a large amount. Not only will harmful substances increase, the nutritional value of tea will be damaged, but also Affect the taste of tea.
3. Acidic drinks
We all know that stainless steel has poor corrosion resistance and is afraid of strong acids. If you hold strong acid drinks for a long time, it may damage human health and also damage its inner tank. In the same way, a large amount of acidic substances are dissolved in the fried Chinese medicine, so it is not suitable to put a vacuum flask.
In addition, juice is not suitable for high temperature storage. The thermos cup has very good airtightness, and the juice with high sweetness can easily breed a large number of microorganisms in the cup, leading to deterioration.
How to choose a qualified vacuum flask:
Under normal circumstances, as long as we buy a regular brand vacuum flask, the probability of problems is extremely low, then how should we choose a vacuum flask?
1, look at the inner tank. First, see if it is 304 stainless steel , which is a nationally recognized food-grade stainless steel. Then see if there are scratches on the surface of the inner tank, and feel whether the inside and outside of the cup body is smooth and the workmanship is rough.
2, look at the lid. Qualified inner lids are made of new food-grade materials and smell no peculiar smell. Twist the lid of the cup, if it is easier to unscrew it, it means the quality is good. If you can't twist it at the beginning, or make a harsh sound, the lid of such a thermos cup will easily break, causing air leakage and water leakage, and the insulation effect will not be good.
3. Look at the manufacturer, adopt the production standard, use precautions, and be assured that it is not a "three-no product".
How to use the thermos cup correctly:
1. Before using the new thermos cup, it must be sterilized with boiling water at high temperature.
2. Before using the thermos cup, it is recommended to scald it with hot water and discard it before continuing to use it. This can improve the thermal insulation performance and avoid the sudden increase in air pressure and due to excessive temperature differences and hot water sprays.
3. Avoid collisions and impacts during use, which will affect the heat preservation 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 lid should be covered to prevent the growth of bacteria.
Finally, Xiao Tian reminds everyone that in order to avoid scalding , it is best to let the boiled water cool down and pour it into a thermos cup.
