The term 'Husk of Grain' refers to the outer layers of a grain, such as wheat or rice. The husk is composed of two parts: BRAN (4 letters) and CHAFF (5 letters). BRAN is the outermost layer of the grain and is rich in fiber, vitamins, and minerals. CHAFF is the innermost layer of the grain and is composed of the seed coat and small pieces of straw. Both BRAN and CHAFF are removed during the milling process to produce white flour.
