Egg proteins can function as a binder in casseroles due to their ability to ____ during cooking.

• A. Coagulate
• B. Emulsify
• C. Gelatinize
• D. Bind with heat

Answer: (A)

Egg proteins function as a binder in casseroles because they coagulate when heated. When the dish is heated, the proteins unfold and then link together to form a solid or semi-solid network that traps moisture and other ingredients, giving the casserole its structure and helping it set firmly. This protein-based network is the primary way eggs hold the components together. Emulsification involves stabilizing fat droplets in a mixture, which is a different function, while gelatinization refers to starch swelling in water, not the protein-based binding you get from eggs.
