Which condition is considered acceptable for grain kernel storage in terms of the part that contains most starch and protein?

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

Answer: (B)

The endosperm is the central tissue of a grain kernel that stores most of the starch and protein. It’s the large, energy-rich portion that becomes the bulk of flour when milled and provides the main source of carbohydrate and gluten-forming proteins in wheat. The hull, bran, and germ have other roles—outer protection, fiber, and fats/vitamins—so they aren’t where the majority of starch and protein reside. So when thinking about storage quality related to the starch and protein content, the endosperm’s condition is the key factor, making it the best focus.
