Tea is not can not be brewed in a thermos cup

No. Use a thermos cup to make tea: Ceramic pots and cups should be used to make tea, and thermos cups should not be used.

Because the tea is brewed in a thermos cup, the tea is kept at a high temperature for a long time, and a part of the aromatic oil in the tea escapes, which reduces the fragrance; Too much tannin and theophylline are leached, which has a bitter and astringent taste, so it also loses some nutrients.

It is well known that there are many benefits of drinking tea. But why do drinking tea have so many benefits? For ordinary people, they don't know why.

With the development of science, it was not until the beginning of the 19th century that the composition of tea was gradually clarified. After modern scientific separation and identification, tea contains more than 450 kinds of organic chemical components and more than 40 kinds of inorganic mineral elements. The organic chemical components and inorganic mineral elements in tea contain many nutrients and medicinal components.

Organic chemical components mainly include: tea polyphenols, plant alkalis, proteins, amino acids, vitamins, pectins, organic acids, lipopolysaccharides, sugars, enzymes, pigments, etc. The organic chemical components contained in Tieguanyin, such as tea polyphenols, catechins, and a variety of amino acids, are significantly higher than those of other teas.

Inorganic mineral elements mainly include: potassium, calcium, magnesium, cobalt, iron, manganese, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine, selenium, etc. The inorganic mineral elements contained in Tieguanyin, such as manganese, iron, fluorine, potassium, sodium, etc., are higher than those of other teas.

No. Because the air permeability of the thermos cup is poor, it is not suitable for making tea. You can choose a purple sand cup, a porcelain cup or a glass.

Soak in a thermos jar.

Tea is not scientific; Ceramic pots and cups should be used to make tea, and thermos cups should not be used. Cause.

Soak in a thermos jar.

Tea leaves, the tea water is kept at high temperature for a long time, and a part of the aromatic oil in the tea escapes, so that the fragrance is reduced; Too much tannin and theophylline are leached, which has a bitter and astringent taste, so it also loses some nutrients.

No. The inner tank of the thermos cup is the same as the inner tank of the thermos bottle The inner tank of the thermos bottle will be filled with water for a long time, and a layer of scale harmful to the human body will be raised, not to mention making tea

No, the taste of the tea brewed is all gone, and you can choose purple sand cups and porcelain cups.

No. It is best to use a professional tea set.

Scientific tea-making technology: tea dosage, tea brewing water temperature, brewing time.

It's up to you!

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.

The dangers of making tea in a thermos cup:

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.

First of all, it will definitely affect the taste. The tea is stuffed in the cup, and the tea aroma is not volatile; The tannin and theophylline in the tea are overflowed in large quantities, which also makes the tea soup too thick, the bitterness and astringency increase, and the taste will not be too good.

Secondly, tea leaves should not be steeped for a long time. Tea polyphenols, vitamins, caffeine, etc. in tea are heat-resistant substances, and soaking in hot water for a long time will cause these beneficial substances to not be well absorbed by the human body.

Moreover, there will be trace amounts of pesticide residues and other substances on the tea, and if it is soaked for a long time, it may lead to excessive heavy metals.

Again, if you don't pay attention to cleaning, it is easy to accumulate tea dirt in the thermos cup. Although the trace heavy metal substances contained in tea scale exist as precipitates and are not soluble in water, if you encounter a poor quality thermos flask? It's not good to let you drink the scum.

The thermos cup can be made into tea and drunk, but it is not recommended because the taste is not good.

Tea contains nutrients such as tannins, tea polyphenols, aromatic substances, amino acids, and a variety of vitamins. Generally, ordinary porcelain cups are used to make tea, which can not only maintain the mellow flavor of the tea, but also retain the nutrients contained in it without loss.

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.

Tea making tips. 1. Grasp the water temperature of making tea.

There are many kinds of tea on the market, different varieties of tea production process is different, some tea pieces are fresh and tender and easy to brew, such as: green tea leaves are fresh and tender, the leaves can not withstand the high temperature when brewing, and the leaves will be scalded when brewing, and the original fresh taste will be lost when brewed; Such as: oolong tea, black tea, these teas belong to fermented tea, the dryness is extremely high, not easy to brew, and the temperature of brewing tea is relatively high.

The most suitable brewing temperature for green tea is 85°C, and the brewed tea soup is refreshing and fragrant, with an excellent taste; Oolong tea and black tea are suitable for brewing with boiling water, which can better stimulate the rich aroma of tea, and the brewed tea is rich and mellow, full of charm.

2. Control the time of making tea.

If you want to brew a pot of sweet and sweet tea, it is particularly important to control the time of making tea, the brewing time is short and can not stimulate the sense of fresh fragrance, and you will feel bitter after soaking for a long time. Black tea needs to be brewed for an additional 5 seconds and 20 seconds to produce a mellow and rich feeling.

No. Do not use a thermos cup to make tea, because the water in the thermos cup will maintain a high temperature for a long time, and the water temperature required for making tea is generally about 80 degrees, if the tea leaves are soaked in water with a temperature of more than 80 degrees for a long time, it will lose its original flavor and become bitter and astringent. You can brew the tea leaves in the teapot first, and then pour the tea into the thermos cup.

A thermos cup, simply put, is a cup that can keep warm. Generally, it is a container made of ceramic or stainless steel and a vacuum layer, with a lid on the top, tightly sealed, and the vacuum insulation layer can delay the heat dissipation of liquids such as water installed inside, so as to achieve the purpose of heat preservation. It is said that magnetized water has miraculous effects.

2. Development**.

You can use a thermos cup to make tea, and a thermos cup can make lemonade. In terms of hygiene, a thermos cup is better just a form of styrofoam, while other beverages or foods are potentially harmful to health and difficult to clean. Citric acid is an acidic food, and it is very likely to corrode the stainless steel inner wall of the thermos cup by soaking lemons in a thermos cup, and it may also lead to heavy metal precipitation, which is very unfavorable to human health.

Lemon is stronger, vitamin C.

Reasons why you can't make tea in a thermos cup:

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.

3. It will cause tea scale, which is not easy to clean.

Often use the thermos cup to make tea after a period of time will accumulate a layer of dirty tea dirt, 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 layer by layer of tea dirt, it is not only unhygienic, but also shorten the life of the thermos cup.

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.

If you're still making tea in a thermos cup, stop it for the sake of your health.
