Environmental awareness, many people are accustomed to have a warm cup, which serves coffee in the morning and tea in the afternoon to refresh themselves. However, is it safe to pack tea and coffee in a warm cup? Zhang Ruiting, Department of Bedology and Bedroom at Xinguang Hospital, said that the stainless steel material has a high stability, and as long as it is not equipped with high acidity, there will be no metal dissolution. However, if you are accustomed to decorating the beverage, you should clean it regularly to reduce the distortion of the smell.
There are many materials for commercially available temperature-saving cups. Currently, the common 18/8 stainless steel temperature-saving cups are highly heat-resistant and stable. They will not be safe when used to hold coffee, tea, etc., but they are easy to accumulate tea stains, coffee, etc. for a long time. They must be cleaned regularly to avoid the smell. In addition, if you soak the tea leaves directly, when the tea leaves are soaked in hot water for a long time, the tea and lenticular acid will be continuously released, which will easily affect the flavor of the tea.
Some people will use stainless steel warm cups to pack milk for drinking. Although metallic substances will not be dissolved, the milk needs to be stored at a low temperature. Although the temperature is slowly increasing in the warm cup, bacteria may grow and cause acidity, which may cause abdominal problems after drinking.
However, Dr. Zhang Ruiting reminds that it is recommended not to use a warm cup to hold bubbles and carbonated beverages, so as not to spray out when the pressure is too high when it is opened. In addition, it is best to avoid using a steel brush or vegetable cloth when cleaning the warm cup to avoid scratches in the bottle and causing the drink pigment or strange smell to adhere to it, thereby reducing the service life of the warm cup.
