How do eggs improve the binding properties of meat mixtures and other foods?

Eggs serve as an essential functional ingredient in food preparation, particularly for their ability to act as a binding agent in meat mixtures and various other food products.12

When added to meat—such as in the preparation of meatloaf—eggs help hold the ingredients together, providing structural integrity to the mixture. This binding property is a result of the unique functional characteristics of egg proteins. As a source of high-quality protein, eggs can coagulate and form a cohesive matrix when heated, which effectively "glues" other ingredients together.21

Beyond their role as binders, eggs are highly versatile in the kitchen. They function as emulsifiers in products like mayonnaise, provide leavening in cake mixes, and contribute to the overall texture and structure of various baked goods. Because of these diverse properties, egg products are widely used by food processors in liquid, dried, or frozen forms to meet specific culinary and manufacturing needs.132
