What Is Potassium iodate?
Potassium iodate is an iodine compound used in iodized salt programs to prevent iodine deficiency disorders and as a flour treatment agent. Iodized salt using potassium iodate is the primary public health tool for addressing iodine deficiency globally, affecting over 2 billion people. JECFA considers potassium iodate acceptable as a flour treatment agent and salt iodization compound. The WHO recommends potassium iodate as the preferred salt iodization agent for tropical climates due to greater stability than potassium iodide. Approved in many jurisdictions.
