Tag: Iodine stability

According to the Morton Salt company, iodized salt contains approximately 0.04 percent dextrose, a small but essential addition. This minuscule amount of sugar is present for a very important reason, answering the common question of why do salt packets have dextrose and other sugar-related additives.

According to a 2023 study published by the National Institutes of Health, salt's iodine concentration is dramatically reduced by exposure to heat and light. This confirms that iodized salt does lose iodine, a process affected by environmental factors and the specific chemical compound used for fortification. Understanding how and why this occurs is vital for preserving its nutritional value.
