Sep 20, 2019

It is not recommended to drink green tea in a thermos.

The composition of tea is very complicated, containing a variety of substances that the human body needs, such as vitamins, amino acids, carbohydrates, etc., but the vitamins in the tea are not heat-resistant, and the water is too hot to destroy the vitamins.

Tea pots and cups should be used for tea. It is not advisable to use a thermos cup. Because the tea leaves are kept in a thermos cup, the tea stays at a high temperature for a long time, and a part of the aromatic oil in the tea leaves, and the flavor is reduced. At the same time, tea contains citric acid, soaking tea with a thermos cup. Generally, the water is too large, the water temperature is too high, so the leaching of citric acid and theophylline is too much, the tea will have a bitter taste, and the citric acid can make the bacterial protein coagulate. It also loses some of the nutrients of the tea.

Tea is not only important for tea, but also has a requirement for water temperature. It is generally suitable for 80 ° C (before boiling and then cooling), so that the tea soup is bright and green, and the taste is fresh and refreshing. At high temperatures, tea soup tends to turn yellow and tastes bitter. As usual, water temperature is high and it is easy to "hot" tea.
