Tea leaves anywhere contain iodine.
Tea contains catechins, cholesteenone, caffeine, and inositol.
Folic acid, pantothenic acid.
and other ingredients that can improve human health. Tea Drinks Tea is known as "one of the top three beverages in the world".
The main organic chemical components are: tea polyphenols, plant alkaloids, protein and amino acids.
Vitamins, pectin, organic acids, lipopolysaccharides.
Sugars, enzymes, filials, pigments, etc.
Inorganic mineral elements.
Mainly: potassium, calcium, magnesium, cobalt, iron, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine, selenium, etc.

Your understanding that tea contains iodine is actually a wrong understanding, tea does not contain iodine, but it is radiation protection.
It is not only iodine that prevents radiation, their mechanisms and principles are different.
Iodine anti-radiation is a physical principle, the thyroid gland absorbs iodine ions, and free iodine is harmful, but iodine saturation is no longer absorbed after eating iodine.
It is a misconception that a large amount of table salt protects against radiation, and that the iodine content of table salt is very small (this protection is not recommended).
Tea contains a large number of polyphenolic compounds and lipids and polysaccharides, which can biochemically react with free radicals, and lipids protect against lead and free radical detachment.

Hairy crab, Benshan, ** Gui contains tea iodine.

When iodophor is mixed with ruined tea leaves, it will become turbid, and it will appear a purple-black liquid at this time.
Whether a reaction is chemical or not is judged by whether the reaction produces new molecules. In the reaction, it is often accompanied by luminescence, heat, color change, and precipitation.
Iodophor is an amorphous conjugate of elemental iodine and polyvinylpyrrolidone. Polyvinylpyrrolidone dissolves and disperses 9% 12% iodine.
The chemical components of tea mainly include water, proteins and amino acids, alkaloids, tea polyphenols, sugars (including starch), organic acids, lipids, pigments, aromatic substances, vitamins, enzymes, inorganic compounds, etc.

I have never heard of iodine in tea, if you want to supplement iodine, it is better to eat more kelp, seaweed, iodized salt, which is very good.

To know if there is a reaction, you must first know what the substance is.
Iodophor is an amorphous conjugate of elemental iodine and polyvinylpyrrolidone (povidone). Polyvinylpyrrolidone dissolves and disperses 9% 12% iodine, presenting itself as a purple-black liquid.
Polyvinylpyrrolidone is most distinctive and valued for its excellent solubility and physiological compatibility. It does not play a practical role in iodophor, but is optimistic about its biocompatibility dissolved iodine. So the reaction of iodophor is the reaction of iodine.
Tea is relatively complex, with as many as 500 kinds of chemical components, including more than 450 kinds of organic compounds and about 30 kinds of inorganic compounds. There are mainly water, proteins and amino acids, alkaloids, tea polyphenols, sugars (including starch), organic acids, lipids, pigments, aromatic substances, vitamins, enzymes, inorganic compounds, etc.
The reaction is that iodine turns blue when it meets starch (iodine goes into the voids of starch); electrophilic displacement with aromatic compounds to form aryl iodide; Oxidizing vitamins (iodine is oxidizing, while vitamins such as vitamin C are reductive). I couldn't do anything else.
Generally speaking, it should be said that the starch turns blue.
Tea has so many effects! It can refresh, cleanse the intestines, brighten the eyes, and fight cancer! It can also prevent oral problems!
