Which function of eggs acts as a binder by coagulating proteins to firm mixtures like meat loaf?

• A. Foams
• B. Binder
• C. Leavening
• D. Emulsifier

Answer: (B)

Eggs act as a binder by coagulating proteins when heated. The proteins in the egg white and yolk unfold and then link together to form a firm network that traps moisture and fat, pulling the ingredients in meat loaf into a cohesive mass. This gives shape and slices cleanly after cooking. Foams rely on air to create light textures, leavening introduces gas to make mixtures rise, and emulsifiers blend fats with liquids, but none of those create the same protein network that binds ingredients together the way coagulated egg proteins do.
