1, bottle cap

The cover of the gourmet mug is frosted outside, so don't worry about dropping it on your hand. Some fake gourmet thermos cups have no frosting on the outside of the bottle cap, which is sticky and soft to the touch.

Step 2: Bottle bottom

The gourmet thermos cup not only has a qualified inspection certificate, but also has an English logo stamped on it, which looks neat and three-dimensional. Moreover, some fakes are easily overlooked at the bottom of the bottle, and the English logo can't be found at all.

Can a gourmet mug make tea? Thermos flask can make tea, not only ordinary black tea, green tea and scented tea, but also all kinds of tea bags, but it is not recommended to keep them in thermos flask for a long time.

Some people think that tea can keep the temperature of the thermos cup, which is a wrong idea. When the substances in tea remain unchanged in time and temperature, too much tea polyphenols will invade tea, which is not good in color or taste. Therefore, for people who like to drink tea, prepare a tea pot so that the tea can be heated when it is cold.

At the same time, it is also because tea is rich in various nutrients, such as vitamins and minerals, as well as tea polyphenols, caffeine, tannins and other components with reasonable functions. Because these nutrients are afraid of continuous high temperature, tea leaves are soaked in high temperature water for a long time, and the tea leaves are thicker and bitter. Aromatic substances will accelerate volatilization, and tea soup will lose its proper aroma. Tannic acid and theophylline are easy to seep out in large quantities, reducing their nutritional value. However, when the temperature exceeds 80℃, a large amount of vitamin C will be lost, and the health care function of tea will be reduced accordingly.

The above is about how to cook the thermos cup, how to identify the authenticity of the thermos cup, and whether the thermos cup can make tea. I hope it will help everyone!
