Although the winter has passed, there are still many people who use the thermos cup to drink water. Especially, soaking wolfberry in the thermos cup is a manifestation of health preservation. So can any liquid in the stainless steel thermos cup be installed? Actually, this is not the case. Friends, please keep in mind that the following four kinds of liquids should not be used with thermos cups.

For the sake of health, these four kinds of liquids must not be put in stainless steel thermos cups

1. Chinese medicine

A large amount of acidic substances are dissolved in the fried traditional Chinese medicine, which can react with the chemical substances contained in the inner wall of the thermos cup and dissolve into the decoction.

And Chinese medicinal materials such as wolfberry and angelica will also have similar reactions. Therefore, don't use thermos cups to soak wolfberry anymore, ceramic cups and glass cups are good choices.

2. Acidic drinks

Some vacuum flasks use high-manganese and low-nickel steel liner, which has poor corrosion resistance, and heavy metals are easy to precipitate in acidic media. Therefore, acidic drinks, fruit juice, coffee, carbonated drinks, etc. should not be packed in thermos cups.

3. Milk

Storing milk in a vacuum flask can easily cause microorganisms to multiply rapidly, leading to corruption and gastrointestinal discomfort.

4. Tea

Tea leaves are easily fermented under the conditions of high temperature and constant temperature in thermos cups, vitamins are destroyed in large quantities, aromatic oils are volatilized, and tannins and theophylline are leached in large quantities, which not only reduces the nutritional value of tea, but also makes tea taste bitter and harmful substances increase.
