Potassium iodate is an oxidizing agent and can therefore cause a fire in contact with combustible materials or reducing agents. Potassium iodate is obtained by reacting potassium base with iodic acid. Potassium iodate is the main chemical compound used for the iodization of common edible salts. It is also used to precipitate thorium, especially to extract it from rare earths. Potassium iodate is also used in the iodination of table salt, in the analysis of arsenic and zinc tests, in iodometry in drug production, as a maturator and dough softener in foods, and as a reagent and feed additive.
Potassium iodate is produced by the reaction of potassium hydroxide with iodine or by the reaction of potassium hydroxide with iodine. This second reaction produces both iodide and iodate. Potassium iodate is an oxidizing agent and may cause fires when in contact with combustible materials or reducing agents. Usually, table salt is produced in an iodized form, which means it contains small amounts of potassium iodide or sodium iodide. The purpose of iodized salt is to provide the needed trace amount of the chemical element iodine, which is essential for the proper functioning of the thyroid gland.
It meets the requirements of the Food Chemicals Codex for the production of high quality potassium iodate, food ingredients and additives and processing aids. It is an effective oxidizing agent and has applications in food production, such as accelerating fermentation reactions in bread dough that make bread rise during baking.
Potassium iodate also has good stability and is approved as an iodine supplement. Iodine is essential for health and is necessary for effective thyroid gland functioning, affecting the body's metabolic and immune functions. In the case of radiation exposure, potassium iodate is also used as a thyroid blocking agent to prevent uptake of radioactive iodine.
Potassium iodate is also used as a basimetric standard for the standardization of strong acids.
On the other hand, potassium iodate is a food ingredient that oxidizes and strengthens the gluten-protein bonds in bread dough immediately after mixing. It accelerates the reactions that make the bread rise during baking.
Our organization also provides potassium iodate analysis services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
