Why can t you drink tea in a thermos cup?

Tea contains tea polyphenols, tannic acid, aromatic substances, amino acids and a variety of vitamins, when boiling water in the teapot or ordinary cup of tea, a large number of beneficial ingredients are dissolved in the water, while tea polyphenols and tannic acid and other components are slightly dissolved in water, so that the color of the tea soup is heavy, there is a bitter taste, which not only reduces the nutritional value of tea, reduces the tea fragrance, but also increases harmful substances. Vitamins are also destroyed because they are not resistant to high temperatures, thus reducing the health care function of tea, so it is not advisable to use a thermos cup to make tea.

At the same time, due to the high water temperature, the aromatic oil in the tea will volatilize a lot, and a large amount of tannic acid and theophylline will exude, which not only reduces the nutritional value of tea, reduces the aroma of tea, but also increases harmful substances.

In addition, nutrients such as vitamin C will be destroyed when the water temperature exceeds 80, and long-term high-temperature soaking will cause it to lose too much, thus reducing the health function of tea.

1. It affects the taste of tea itself and loses its health care effect.

Because the temperature of the thermos cup is generally relatively high, although the tea can be quickly distributed, but it also reduces the fragrance of the tea, and the tea that has been scalded at high temperature will lose the nutrients it contains, thus losing the health care effect of the tea, so it is not suitable to use the thermos cup for tea.

2. It will be harmful to health.

I believe that most of the people who use a thermos cup to make tea are office people, in fact, the tea itself has many beneficial effects on the human body, but if it is scalded by the thermos cup at high temperature, it will lose a lot of nutrients, leaving only the astringency of the tea, and most of the people in the office are because the tea can refresh themselves, so they will definitely drink two or three cups or even more a day, too much drinking the tea made in the thermos cup will lead to insomnia, dreams and other symptoms, so now friends who are still using the thermos cup to make tea should pay attention.

Since vitamins are not resistant to high temperatures, long-term high-temperature soaking will destroy them in large quantities, reducing the nutritional value of tea. Moreover, long-term high-temperature soaking will increase the harmful substances in the tea, if you drink this tea for a long time, it is easy to cause a variety of diseases in the digestive system, cardiovascular system, nervous system and hematopoietic system, etc., and endanger health. Therefore, it is not advisable to use a thermos cup to make tea.

I can make tea with a thermos cup.

If you use a thermos cup to make tea, you can also drink it, but because the thermos cup can maintain a high temperature, it is easy to volatilize the aromatic substances in the tea quickly, thereby reducing the tea aroma. In addition, high temperature can also make tannins, tea polyphenols, etc. exud too much, making the taste of tea bitter, and vitamins are not resistant to high temperature, so if you soak tea at high temperature for a long time, it will destroy a lot of vitamins, resulting in the loss of nutrients.

Therefore, if you use a thermos cup to make tea, it is recommended to drink it in time and not to brew it for too long, so as not to affect the taste and lose nutrients.

You need to pay attention to making tea:

1) Throw away the brewed tea leaves: Most people throw away the used tea leaves after brewing the tea. In fact, this is uneconomical, and the tea should be chewed and swallowed, because tea contains more carotene, crude fiber and other nutrients.

2) Brewing tea with boiling water: Brewing tea with boiling water will destroy a lot of nutrients. For example, vitamins C, P, etc., will be destroyed when the water temperature exceeds 80, and it is easy to dissolve too much tannin and other substances, making the tea bitter and astringent.

Therefore, the water temperature of making tea should generally be mastered at 70 -80. Especially for green tea, if the temperature is too high, the tea leaves are ripe and turn into black tea, which will lose the original fragrance and cool taste of green tea.

3) Tea brewing time is too long: Tea leaves are best drunk after soaking for 4-6 minutes. As a result, 80% of the caffeine and 60% of the other soluble substances have been soaked.

If it takes too long, the tea will have a bitter taste. Tea that has been boiled for a long time on a thermos or stovetop is prone to chemical changes and should not be consumed again.

Because if the tea leaves are soaked in high-temperature water for a long time, just like warm decoction, tea polyphenols, tannins and other substances will be leached out in large quantities, making the tea rich in color and bitter and astringent.

At the same time, the high water temperature will also make the aromatic oil in the tea volatilize rapidly, reducing the fragrance of the tea. In addition, nutrients such as vitamin C can also be destroyed when the water temperature exceeds 80, and the health value is greatly reduced. Therefore, it is not advisable to use a thermos cup to make tea.

1. Induce disease.

Doing so not only does not maintain health, but will destroy the nutrients in the tea, leach a large amount of tannic acid and theophylline, and increase harmful substances. Long-term consumption will harm health and lead to a variety of diseases of the digestive, cardiovascular, nervous and hematopoietic systems.

2. Affect the taste of tea.

The temperature of the thermos cup is relatively high, if the tea leaves are soaked at this temperature for a long time, the nutrients of the tea itself will disappear, and the tea polyphenols, tannins and other substances contained in the tea will leach out in large quantities, making the tea heavy in color and bitter and astringent, so it is not suitable to use the thermos cup for making tea.

3. Reduce the health care function of tea.

If the tea is soaked in a high temperature state for a long time, the aromatic oil in the tea will quickly volatilize, reducing the fragrance of the tea, and the vitamin C contained in the tea will also be destroyed, so as to lose the health care function of the tea.

4. It is easy to generate tea scales and is not easy to clean.

Tea brewed in the cup for a long time will accumulate a layer of dirty tea scale, often use a thermos cup to brew tea after a period of time will accumulate a layer of dirty tea scale, and it is not easy to clean, originally with a high temperature cup of tea there is no fragrance, if the long-term accumulation of a layer of tea scale, it is not only unhygienic, but also will shorten the life of the thermos cup.
