Oat hull fibre is a fine powder generated via mechanical processing from the hulls of oat kernels. The fibre is added to increase overall dietary fibre of dough, which is largely absent from white wheat flour, help retain moisture and extend shelf life, and increase dough yield due to its water-retaining properties.

Health considerations

Oat hull fibre is considered an insoluble fibre, and thus its health benefits are primarily increasing bowel transit time by increasing bulk of stool. See: Insoluble fiber.
