The term SEED HUSK is composed of two words, ARIL and BRAN. An ARIL is a fleshy or papery covering that surrounds the seed of some plants, such as pomegranates and yews. BRAN is the hard outer layer of cereal grains, such as wheat, oats, and barley. It is removed during the milling process to make white flour, but it is often added back into whole grain products. Together, these two words refer to the protective outer layers of a seed, which are important for protecting the seed from damage and helping it to germinate.
