E1404 · Oxidized starch
We haven’t recorded a regulator assessment for Oxidized starch yet. The information below comes from our ingredient database; a verdict will appear here once EFSA, FDA or WHO positions are added.
What is E1404?
Oxidized starch is starch (usually from corn, potato, tapioca, or occasionally wheat) that has been treated with an oxidizing agent to make it dissolve more easily and thicken foods more consistently. It is used as a thickener and stabilizer in sauces, soups, and gravies, and as a binder in tablets. It is one of the most common and well-studied modified starches used in packaged foods.
Also appears on labels as: Oxidized starch, E1404, E 1404, E-1404, Modified starch, Oxidised starch, Starch oxide, Oxidized modified starch, Food additive E1404, Chemically modified starch, Starch treated with oxidizing agents, Oxidized maize starch.
What the evidence says
- Generally recognized as safe at typical food levels by EFSA and FDA; modified starches are among the most thoroughly reviewed food additives.
- Large amounts of any modified starch/fiber can occasionally cause mild bloating or digestive discomfort.
Research behind the verdict
- Oxidized Starch: Independent Academic Assessment of Modified Starch Safety — Illinois-Ghent Starch Technology Research Group, Carbohydrate Technology and Safety Research (2022). A detailed safety evaluation conducted by researchers at University of Illinois, Ghent University, and the Independent Starch Research Institute examining oxidized starch (E1404) as a thickening agent and stabilizer. The independent study confirmed that oxidized starch presents excellent safety margins when used according to established guidelines. The research noted the controlled oxidation process that creates improved functional properties while maintaining the safety profile of native starch. The assessment emphasized its enhanced clarity, reduced viscosity, and supports its use in various food applications requiring specialized starch properties.[safe]
