Many people like to drink tea, will tea scale cause harm to the body? How to easily remove tea dirt?

The thick layer of tea dirt accumulated on the inner wall of the old teapot over the years is known as the tea mountain in tea culture. The traditional belief is that it is this kind of brown tea stain that looks like the best that is the secret to brewing flavorful tea, so the family is not allowed to clean the tea stains on the teapot and teacup. Tea stains, also known as tea stains, refer to the sediment left on the wall of the cup after the chemical components in the tea are oxidized after contact with the air.

It contains heavy metals such as mercury, lead, etc. Long-term ingestion can accumulate in the body, increasing the risk of nervous system dysfunction and hindering the body's digestion and absorption function.

Tea scale is a water-insoluble stone substance formed by the combination of polyphenol oxides in tea and minerals in water (calcium ions, magnesium ions, etc.). Tea utensils that have not been cleaned for a long time are prone to mold growth in a humid environment. Tea scale itself is harmless to the human body, but long-term consumption of tea containing mold is harmful to the human body, so the tea set should be cleaned after each tea drink; Some people think that tea dirt is easy to breed bacteria.

There is nothing wrong with this understanding, as the attachment of tea stains to the cup undoubtedly provides a breeding platform for some external bacteria. Therefore, if limescale is not treated in time, it may have certain effects on the body, both positive and negative.

Tea scale is caused by the oxidation reaction of tea polyphenols and metal substances in tea rust in the air. The dirt on the teacup is yellow, and the composition of the dirt is the precipitation of alkaline substances in the tea. If you want to remove these alkaline dirt, you need to add acidic substances, such as edible vinegar, acetic acid, etc., to neutralize the alkaline dirt and acidic substances, and then rinse with water to remove the dirt.

The main ingredient of rust is calcium carbonate, because it is insoluble in water, so it will form on the walls of the bottle, and there is acetic acid in vinegar, which can react with calcium carbonate to produce salts, so it can be washed off.

If there is a little dirt, you can wash it with warm water. If your cup is likely to use it for a long time to make tea, the dirt left behind will be more stubborn. If the steeping time is too long, many tea sets are brown and cannot be washed off with water.

At this time, you can squeeze a small amount of toothpaste on the tea set and apply it evenly to the surface of the tea set with your hands or a cotton swab. After about a minute, wash these tea sets with water so that the tea dirt on the tea sets is easy to clean.

Checking and transferring accounts will cause certain harm to the body, which will lead to serious gastrointestinal digestive problems, and will lead to serious symptoms of three highs, high blood pressure, high blood lipids, and high blood sugar. After each cup of tea, be sure to soak your cup in boiling water and wash it with a special detergent to remove the tea stains.

Tea scale will cause harm to the body, because if the tea scale is not cleaned for a long time, it will breed a lot of bacteria, which can easily lead to gastroenteritis or diarrhea. You can apply some toothpaste to the tea stain, you can soak it in white vinegar for 20 minutes, or soak it in table salt for 20 minutes and gently wipe it with a steel wool ball.

Many people who love tea are worried that tea stains will cause harm to the body, but this concern is superfluous, and Cha Bu will be excreted from the body by itself through the digestive system. Even if there is a small amount left, some materials will not cause harm to the body in the body.

Elemental analysis showed that most of the components of tea scale were carbon and oxygen, from polyphenol polymers, and a small amount of potassium, calcium, magnesium, aluminum, zinc, selenium and other elements. Metal elements are mainly in the form of carbonates or hydroxides that are insoluble in water, of which calcium is the main promoter of the formation of tea scales, mainly from the water in which tea is made.

The surface of the overnight tea soup often has a "film of oil" with a metallic luster, which makes people mistakenly think that there is some kind of heavy metal in it. However, the release of heavy metals into the tea soup by the tea dirt deposited in the tea soup is not logical in itself. In fact, there is no obvious difference between the composition of this film and the tea scale on the cup wall, and it is also dominated by tea polyphenol polymers.

Heavy metal pollutants such as lead, arsenic, cadmium, and mercury are not the main metal elements of tea scale, so tea scale is not harmful to the human body.

Harmful, tea scale is produced due to the oxidation reaction of tea polyphenols in tea and metal substances in tea rust in the air, in which cadmium, lead, iron, arsenic, mercury and other metals and nitrite and other substances harmful to the body will adhere to the smooth surface of the teacup. Tea stains enter the body with tea drinking, combine with nutrients such as proteins, fats and vitamins in food, and form insoluble precipitates, hindering the absorption of nutrients. At the same time, these oxides can also cause neurological and digestive system pathologies and dysfunction when they enter the body, and even cause premature aging of the human body.

There are a lot of harmful metal substances in tea scale, and some even contain carcinogens such as nitrite, which are harmful to the body. How to clean tea dirt? Let's take a closer look!

Drinking water contains some inorganic minerals, calcium, manganese and harmful heavy metal ions, such as cadmium, mercury, arsenic, etc. When the water is heated, with the increase of water temperature, the solubility of some calcium and magnesium ions decreases, and the concentration of insoluble salts continues to increase.

Tea stains are harmful to the body.

Tea scale contains cadmium, mercury, arsenic and other harmful heavy metal substances, some tea scale even contains nitrite and other carcinogens, long-term do not clean the tea cup, drink water containing tea scale, is harmful to the body.

Tea scale enters the digestive system and is easily combined with proteins, fatty acids and vitamins in food to form a variety of harmful substances, which will not only hinder the absorption and digestion of nutrients in food by the human body, but also damage multiple organs, such as neurological, digestive, urinary and hematopoietic system lesions, and even cause premature aging of the human body.

Tips:

After the tea has been left for a long time, a layer of tea dirt will be attached to the tea set, which can be quickly removed by scrubbing with salt or vinegar. People who love tea should wash the tea utensils frequently, so that the tea can play a better health care role.

Salt to remove tea scale Salt has a good stain removal effect. Pour a little salt into the tea set, scrub it carefully with your hands or brush, and then wash it with water, repeating twice to remove the tea dirt attached to the tea set.

Vinegar to remove tea scale Vinegar is acidic and can chemically react with tea scale to form a substance soluble in water, which plays a role in removing stains. Pour a little vinegar into the tea set, let it stand for five minutes, and then scrub it with a brush, which can easily wash off the tea dirt in the tea set.

Edible alkali to remove tea scale Edible alkali has a good ability to remove stains, especially for oil stains, and can also remove tea scale. Pour a little edible alkali into the tea set, add a little water, moisten it slightly, and then scrub it with a brush until the tea dirt is removed.

Potato peel to remove tea dirt Put the potato skin into the tea set, pour boiling water, cover and simmer for 5-10 minutes, and shake it a few times to easily remove the tea scale. Because the potato skin is rich in starch and has a strong adsorption power, it is easy to remove the tea dirt that adheres to the tea set.

Toothpaste to remove tea scale In addition to cleaning teeth, toothpaste also has a good effect on removing tea scale. Squeezing an appropriate amount of toothpaste on the brush and carefully brushing along the inner wall of the tea set can also effectively remove the tea dirt in the tea set.
