Oat Hull Fiber

Oat hull fiber is a type of dietary fiber derived from the outer layer of oats. It is produced by milling and separating the hulls from the oat groats, often using mechanical processes. The resulting material is a concentrated source of insoluble fiber.

Oat hull fiber is added to foods as a source of dietary fiber, contributing to texture and bulk. It is commonly found in baked goods like breads and muffins, as well as cereals and cookies. Manufacturers use it to increase the fiber content of products without significantly altering taste or appearance.

Oat hull fiber is generally recognized as safe (GRAS) by the FDA for use in food. As a source of insoluble fiber, it can contribute to digestive regularity when consumed as part of a balanced diet. International bodies like JECFA have evaluated dietary fibers, but specific evaluations for oat hull fiber alone are not always detailed. Evidence generally supports the role of dietary fiber in digestive health.
