Oat Fiber

What is Oat Fiber?

Soluble fiber extracted from oat hulls.


Oats are mainly grown in the northern Midwest states in the United States.


Used to increase fiber in a product to obtain a high fiber claim. Oat fiber is usually chosen because it is label friendly. Oat fiber can absorb up to seven times its weight in water, so the product must be formulated to allow enough water for hydration of all ingredients. Oat fiber can be especially useful in lowering water activity for extended shelf-life products.


90% insoluble fiber, less than 5% soluble fiber. A high percentage of oat fiber are beta glucans.


Add fiber to increase moisture retention for longer shelf-life in baked goods. Usage level range is between 0.5 – 2% flour weight, and would normally alter the viscosity of the product. More water may be needed in the product.


Good source of beta-glucan fiber. May reduce the risk of heart disease.
