Which kernel component is primarily used to produce refined flour?

• A. Endosperm
• B. Bran
• C. Germ
• D. Hull

Answer: (A)

Refined flour comes from the starch-rich inner portion of the grain called the endosperm. In milling, the bran (the fiber-rich outer layers) and the germ (the oil-rich embryo) are removed, leaving mostly endosperm, which is ground into the fine white flour most people know. Bran adds texture and fiber, germ adds fats and vitamins, and the hull or husk is an outer layer that's typically left out. So the endosperm is the best choice because it’s the part that remains and becomes refined flour. Some refined flours are later enriched to restore lost nutrients, but the primary component used to make refined flour is the endosperm.
