Is e917 vegan?

E917 is the E-number for potassium iodate, an inorganic chemical compound used in the food industry primarily as a flour treatment agent and dough conditioner. It also appears in fortified products, such as iodized table salt, where it serves as a stable source of iodine. In commercial baking, manufacturers add potassium iodate to wheat flour to oxidize the dough, which strengthens gluten structures, enhances gas retention, and improves the final rise and crumb texture of baked goods like breads and rolls.

This additive is produced synthetically on an industrial scale. It is commonly prepared by reacting potassium compounds, such as potassium hydroxide, with iodine or iodic acid derived from natural mineral brine or caliche ore deposits. The entire manufacturing process utilizes purely mineral and inorganic chemical reagents, with no animal tissues, animal byproducts, or animal-derived processing aids involved at any stage. Consequently, E917 is vegan.
