E916 – Calcium iodate
Flour bleaching agentDescription
White or almost white, crystalline powder or granules
Notes
Calcium iodate is a white, crystalline powder that's created by combining calcium (a mineral) with iodate (a form of iodine that's been combined with oxygen). This compound is manufactured through chemical processes that ensure the iodine is in a stable form that won't easily break down during food storage and processing, making it more reliable than some other forms of iodine for food applications. This additive serves as a flour improver, which means it helps make bread and other baked goods better in several ways. When added to flour, calcium iodate strengthens the gluten network (the protein structure that gives bread its texture), resulting in better rising, improved texture, and more consistent baking results. You'll find it used in commercial bread production, flour milling, and other baked goods manufacturing where consistent, high-quality results are important. Calcium iodate is a synthetic additive that's suitable for vegetarians and vegans since it contains no animal-derived ingredients. An important benefit is that it also serves as a source of iodine, an essential nutrient that many people don't get enough of in their diets. It's approved for use in many countries and is considered safe when used in the small amounts typical for flour improvement. Some regions have specific regulations about iodine fortification in flour, making this additive particularly valuable for public health nutrition programs.
