Will tea stain be harmful to your health? Teach you to easily remove the tea stain in the cup

now many people like to drink tea. They like to drink a cup of warm tea on a cool morning to make a beautiful start to the day. Whether it’s ceramic, glass or enamel vessels, there will be tea stains in the cup after one or two times of use, but over time, it has become the biggest flaw that destroys the good atmosphere. What can we do to get rid of these annoying traces? Let’s have a look with you.

The main component of tea scale is tea polyphenols, and a small amount of metal ions also participate in the formation of tea scale. Because green tea has more polyphenols, it is easier to form tea scale, while black tea and black tea after deep fermentation have less tea scale.

of course, the components of tea scale formed by different types of tea are basically similar. Tea scale is a polymer produced by the oxidation of tea polyphenols in air, so it is mainly formed near the water line and attached to the inner wall of the container.

showed that the molecular weight of the polymer in tea scale increased gradually with the extension of time, which means that the polymerization of polyphenols is still slow. Therefore, it makes sense that the longer the tea scale lasts, the harder it is to remove it.

Heavy metals are not the main metal elements in the tea stains; Oil film;, People mistakenly think that there is some heavy metal in it.

in fact, elemental analysis shows that most of the components of tea scale are carbon and oxygen, which come from polyphenol polymer, and a small amount of potassium, calcium, magnesium, aluminum, zinc, selenium and other elements. Metal elements mainly exist in the form of carbonates or hydroxides insoluble in water, and calcium is the main promoting factor for the formation of tea scale, mainly from the water of tea making.

lead, arsenic, cadmium, mercury and other heavy metal pollutants are not the main metal elements of tea scale, so there is no need to worry when drinking tea.
