Millet bran is rich in fats, and not removing it might reduce shelf life, as it could become rancid faster. De-branning will also reduce cooking time, making the grain softer and less chewy.
As it contains high levels of fibre and Vitamin B, bran is used as a dietary supplement and added to breads and breakfast cereals. It is also used in soups, fish stews, pastry, and cakes.
