Furthermore, its unique texture and nutty flavor profile make it a versatile ingredient that adds depth to various dishes. Embrace the humble bran by experimenting with different types such as wheat bran, rice bran, and oat bran to enhance both the flavor and nutritional value of your meals.
How is the bran layers removed?
The bran layers are typically removed through a process called milling, which involves several steps to separate the bran from the endosperm and germ of the grain. In this process, the grains are first cleaned to remove any debris or impurities, and then passed through a series of roller mills that gradually break down the grain into smaller particles. As the grain is milled, the bran layers are progressively removed, resulting in a refined flour that is mostly composed of the starchy endosperm. The removal of the bran layers can be achieved through various milling techniques, including pearling, where the grain is subjected to abrasion to remove the outer layers, or through the use of specialized milling equipment that uses a combination of rollers and sieves to separate the bran from the other components of the grain, resulting in a range of flours with varying levels of bran content, from whole grain flours that retain most of the bran, to refined flours that have most of the bran removed.
What happens to the removed bran layers?
When flour is refined, millers is separated from the starch-rich endosperm to produce refined flour. But what happens to the removed bran layers? Typically, the bran is sold separately as a nutritious additive for baked goods, cereals, and animal feed. Rich in fiber, vitamins, and minerals, it’s a valuable byproduct that can enhance the nutritional profile of various products. In some cases, bran is also used to produce bran oil, a healthy alternative to traditional vegetable oils.
