Oat Gum
The short version
An β-glucan-rich gum from oat hulls — a clean-label thickener with documented cholesterol-lowering effects.
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Where it comes from
Extracted from oat-grain endosperm by aqueous milling and purification — concentrates the (1→3)-(1→4)-β-D-glucan polymer naturally responsible for oat porridge's characteristic viscosity. The same molecule that drives the FDA-approved oat-fiber cholesterol-lowering claim at 3 g/day.
How it's used
Used in oat-milk products for body and creaminess (natural inclusion rather than added thickener), in clean-label cereal coatings, ready meals, and supplements. Marketed alongside the cholesterol-lowering health claim where regulatory frameworks allow.
Safety profile
ADI not specified — considered safe (treated as a soluble-fiber food rather than an additive in many jurisdictions). The EU re-evaluation moved E411 out of the active additives list — it is now usually labeled simply as 'oat fiber' or 'oat β-glucan'.
Physical & chemical properties
Off-white to cream-colored powder. Forms viscous solutions in water. Heat-stable in typical food applications.
Regulation worldwide
Largely transitioned from additive to ingredient status in the EU (no longer required to carry the E-number). Permitted globally as a natural-fiber ingredient.
