E1403 – Bleached starch
ThickenerDescription
Modified starch derived from various sources (corn, potato, wheat, tapioca) treated with bleaching agents like chlorine, sodium hypochlorite, or hydrogen peroxide to alter its properties (viscosity, texture, stability).
Notes
Bleached starch begins as regular starch from corn, potatoes, wheat, or other plants, but it undergoes a bleaching process using chlorine, sodium hypochlorite (similar to household bleach), or hydrogen peroxide. This treatment removes the natural color from the starch, making it whiter and also changing some of its functional properties. The bleaching agents are removed or neutralized during processing, leaving behind a modified starch that behaves differently than the original. This ingredient serves as a thickener, stabilizer, and binding agent in foods, similar to regular starch but often with improved performance in certain applications. You'll commonly find E1403 in baked goods, confectionery, processed meats, and various packaged foods where a clean, white appearance and specific texture are desired. It's particularly popular in products where manufacturers want to avoid any off-white or yellowish tint that natural starches might contribute. Although it starts from natural plant sources, the chemical treatment makes this a processed ingredient rather than a natural one. It's typically suitable for vegetarian and vegan diets, but those with celiac disease should verify the source if they need to avoid gluten. The bleaching process is regulated and considered safe by food authorities, with strict limits on any chemical residues that might remain.
