Cup of tea will make nutrition loss of insulation

People like to put a mug in the office drawer, prepare the tea at any time, work began with a mug to drink tea, drink tea after work were still warm. I'm that way. The time for work this morning, by the way to the tea shop to buy a package of tea, to the office is preparing to take tea mug, was stopped by Wang to. Cup of tea with the heat, he said the loss of nutrition. Tea is rich in protein, fat, sugar, vitamins and minerals and other nutrients, is a natural health drink, which contains polyphenols, caffeine, tannin, tea pigments, but also has a variety of pharmacological effects. If mug tea, tea, long soak in hot water, boiling like a warm fire, like polyphenols, tannins and other substances are a large number of leaching, so that the color of tea strong, with bitter taste. Also, because the water temperature remained relatively high tea in a large number of volatile aromatic oils will soon, tannin, theophylline lot of leaking, so not only reduces the nutritional value of tea, a decrease of tea, but also to more harmful substances.

In addition, vitamin C and other nutrients in the water temperature exceeds 80 ℃, will be destroyed, so the loss will be a long hot soak too much, thereby reducing the health functions of tea. If you drink hot tea, tea can be brewed or ceramic teapot, tea Well, after the cup and then poured into the insulation.
