Can stainless steel water bottles be filled with saline?

In this cold winter, whether it is a student party, an office worker, or an uncle or aunt walking in the park, they will carry a thermos cup with them. It can preserve the temperature of hot drinks, allowing us to drink hot water anytime and anywhere, giving us Bring warmth. However, many people’s thermos cups are not only used to hold boiled water, but also other drinks, such as tea, wolfberry tea, chrysanthemum tea, and even various beverages. But actually do you know? Not all drinks can be filled in thermos cups, otherwise they may be harmful to health. Today I will share with you 5 kinds of drinks that are not suitable for filling in thermos cups. Let’s learn about them together!

The first one: milk.

Milk is a nutritious drink that is deeply loved by people. Many friends have the habit of drinking milk every day. In order to prevent the heated milk from getting cold, they pour it into a thermos cup for easy drinking at any time. But in fact, this approach is not good, because milk contains a lot of microorganisms. If we put the milk into a thermos cup, the long-term warm environment will cause these microorganisms to multiply rapidly, resulting in deterioration. Drinking such milk is not only nutritious, but also can cause symptoms such as diarrhea and abdominal pain if the gastrointestinal condition is not good. Therefore, it is best not to store our milk in a thermos cup. Even if it is stored in a thermos cup, try to drink it within an hour to avoid deterioration.

The second type: salty water.

Water with salt content is not suitable for use in thermos cups, because the inner tank of the thermos cup has been sandblasted and electrolyzed. The electrolyzed inner tank can avoid direct contact between water and stainless steel and physical reactions. However, table salt is corrosive. If we use a thermos cup to hold salt water, it will corrode the inner tank wall. This will not only affect the service life of the thermos cup, but also cause the insulation effect to decrease. Even salt water will corrode the coating inside the thermos cup and release some heavy metals, posing a potential threat to our health. Therefore, drinks containing salt are not suitable for use in thermos cups for long periods of time.

The third type: tea tea.

Many people use thermos cups to brew tea and drink it, especially older male friends. The thermos cups are basically filled with brewed tea. But in fact, this approach is not good. Tea contains a large amount of tannins, theophylline, aromatic oils and other nutrients. These ingredients will be destroyed if they are exposed to high temperatures. Tea leaves that have had their nutrients destroyed will not only lose their aroma, but will also taste slightly bitter. In addition, using a thermos cup to brew tea for a long time will leave a lot of tea stains on the surface of the inner pot, which is difficult to remove, and the water cup will look black. Therefore, we try not to use a thermos cup to brew tea for a long time.

The fourth type: acidic drinks.

Some friends also use thermos cups to carry juice or carbonated drinks, many of which are acidic. But in fact, acidic drinks are not suitable for use in thermos cups. Because the stainless steel material in the thermos cup will be corroded when it encounters acidic items, causing damage to the coating of the liner and releasing the heavy metals inside, drinking such water will also cause harm to the human body. Therefore, it is best not to use a thermos cup to store some acidic drinks. We should try to use glass or ceramic containers.

The fifth type: traditional Chinese medicine.

Traditional Chinese medicine is also a drink that is not recommended to be filled in a thermos cup. Some friends may need to drink traditional Chinese medicine frequently due to physical reasons. For convenience, I will choose to use a thermos cup to hold Chinese medicine, which is very convenient to carry. However, the acidity and alkalinity of traditional Chinese medicine vary. When we put it in a thermos cup, the ingredients inside may react with the inner wall of the stainless steel and dissolve into the decoction. This will not only affect the efficacy of the medicine, but may even cause adverse effects on the body. substance. It would be better for our Chinese medicine to be packaged in glass or ceramic cups.
