wheat bran

Wheat bran is the hard outer layer of the wheat kernel (Triticum aestivum), consisting of the pericarp, testa, and aleurone layer. It is produced as a byproduct of grain milling when the bran and germ are mechanically separated from the starchy endosperm during refinement to white flour. The resulting product is coarse, fibrous, and tan to brown in color, with a slightly nutty, earthy flavor and a texture ranging from flaky to powdery depending on particle size. Wheat bran comprises roughly 14-15% of the whole grain by weight and is rich in dietary fiber, B vitamins, minerals, and phytonutrients concentrated in the outer protective layers of the kernel.

Nutritionally and functionally distinct from whole wheat flour, wheat bran is primarily valued as a concentrated source of insoluble fiber and is often recombined with refined flour or used independently in various food products.

Wheat bran is primarily used to increase dietary fiber content and nutritional density in breads, cereals, muffins, and baked goods. It is commonly incorporated into whole grain and multi-grain formulations, breakfast cereals, granola bars, and health-conscious baked products. In home baking, wheat bran is added to bread doughs, quick breads, and pancake batters at ratios of 5-20% by weight, though excessive amounts can result in dense, dry products due to the bran's water-absorbing properties. Beyond baking, it appears in smoothie bowls, yogurt toppings, meat loaves, and as a breading component. Wheat bran requires hydration for optimal incorporation and should be adjusted for in liquid ratios to prevent textural problems in finished products.
