To make oat bran at home, pulse quick or rolled oats in a food processor. If rolled oats are unavailable, use whole grain oats, and sift after milling to separate the bran.
Oat bran is the outer husk of the oat grain, and it is high in nutritional value and rich in fiber. The bran is an integral part of the oat grain and is different from the chaff or shell that covers the grain. To make oat bran at home, choose whole grain oats that still have the bran on them. Empty the oats into a blender, and blend it until it forms a coarse flour. Sift the flour if required to separate the bran from the flour, and store it in an air-tight container to prevent it from rotting.
Oat bran is a healthy alternative to breadcrumbs as long as a crunchy finish isn't required. Use it in place of cornstarch as a thickening agent or as an alternative to regular flour. Oatmeal muffins and oatcakes taste delicious when made with oat bran. Add it to thicken soupy oatmeal or in place of oatmeal, or use it along with breakfast cereals for balanced nutritional value and dietary fiber.
