Oat dietary fiber is a kind of ripe dietary fiber powder made by our company through modern wall breaking technology of oat bran. After activation treatment, the molecular structure of oat bran is reorganized, insoluble dietary fiber in cell wall is transformed into soluble dietary fiber, and other trace elements are released to the maximum extent. It has the characteristics of good taste and easy to temper. Oat bran contains the most dietary fiber, especially the most abundant -glucan known as the "noble dietary fiber". More than 95% of the water-soluble fiber in oat is distributed in oat bran after endosperm removal.
