Put it in a thermos cup, from health to poison! These 4 types of drinks cannot be filled with thermos cups! Hurry up and tell your parents~
For the Chinese, the vacuum flask is one of the indispensable “artifacts” in life. Whether it is an elderly grandparent or a young child, especially in winter, they can take it wherever they like.
However, if the thermos cup is not used well, it will not only fail to maintain health, but also bury hidden dangers for your health! Before you understand this truth, you must know the material and working principle of the thermos cup. The inner tank of the thermos cup is generally made of stainless steel, and some chromium, nickel, manganese and other elements are added during the production process to improve the performance of the steel and make it less likely to rust.
The reason why the thermos cup can maintain temperature is because of its special structure: the middle is a double-layer bottle liner, and the middle is evacuated into a vacuum state. Without a transfer medium, the air will not circulate, thereby inhibiting the occurrence of heat conduction to a certain extent.
However, not all drinks can be put into a thermos cup. For the following 4 drinks, it is not suitable to use a thermos cup. The state of being evacuated. Without a transfer medium, the air will not circulate, thereby inhibiting the occurrence of heat conduction to a certain extent.
However, not all drinks can be put into a thermos cup, and the following 4 drinks are not suitable for a thermos cup.
1. It is not suitable to make tea
Tea leaves are rich in proteins, lipids and other substances, as well as tea polyphenols and tannins. If you use a thermos cup to make tea, it will cause the tea leaves to be in high-temperature water for a long time, which will cause a large amount of tea polyphenols and tannins to flow out, and the taste will also become very bitter.
Secondly, the temperature of the water in the thermos cup is generally relatively high, and the nutrients of the tea soaked at high temperature will be lost in a large amount, which will reduce the efficacy of the tea.
In addition, the color of the thermos cup will change when it keeps hot tea for a long time. It is recommended to use tea bags to brew it when going out.
2. It is not suitable to hold milk
Some people put hot milk in a thermos cup for easy drinking. However, this method allows the microorganisms in the milk to multiply rapidly at a suitable temperature, leading to spoilage and easily causing diarrhea and abdominal pain.
Because milk is in a high temperature environment, nutrients such as vitamins will be destroyed, and the acidic substances in milk will also chemically react with the inner wall of the thermos cup, which will affect human health.
Under normal circumstances, there is no problem if the milk in the thermos is drunk in time, but due to long-term storage, it will cause a large number of bacteria to grow, and the quality of the milk will also be reduced or even deteriorated. Including soy milk, it is not suitable to use a thermos cup.
3. It is not suitable to hold acidic drinks
The liner material of the thermos cup is not afraid of high temperature, but it is most afraid of strong acid. If it is filled with acidic drinks for a long time, it is likely to damage the liner.
In addition, in order to avoid the destruction of nutrients, fruit juice is not suitable for high temperature storage. The thermos cup is well sealed, and drinks with high sweetness are prone to breed a large number of microorganisms and cause deterioration.
4. It is not suitable to install traditional Chinese medicine
Some people also like to soak Chinese medicine in a thermos cup, which is convenient for carrying and drinking. However, the fried traditional Chinese medicine generally dissolves a large amount of acidic substances, which easily react with the chemical substances contained in the inner wall of the thermos cup and dissolve into the decoction, causing adverse effects on the human body.
Regarding how to use the vacuum flask correctly, science must be respected. Don’t let the “artifact” that was supposed to bring convenience to life become a burden that blocks your heart!
