Eggs play a vital role in determining the texture of baked goods through several mechanisms:

Structural Contribution

Protein Coagulation: Eggs contain proteins that coagulate when heated, providing structure and stability to baked goods. This is particularly important in cakes, cookies, and pastries, where the proteins help create a matrix that holds the final product together.
Binding Agent: Eggs act as natural binders, helping to hold together the other ingredients in a recipe. This is crucial for maintaining the integrity of the baked good during and after baking.

Leavening Properties

Air Incorporation: When eggs, especially egg whites, are beaten, they trap air. This air expands during baking, contributing to a light and airy texture. This leavening effect is essential in recipes like soufflés and meringues.

Moisture and Richness

Moisture Content: Eggs are composed of a significant amount of water (about 70%-75%), which helps hydrate the dry ingredients in a batter. This moisture is key to preventing dryness and ensuring a tender crumb.
Fat in Yolks: The fat content in egg yolks adds richness and tenderness to baked goods. This richness enhances mouthfeel and flavor, contributing to a desirable texture.

Emulsification

Lecithin in Yolks: Egg yolks contain lecithin, a natural emulsifier that helps blend fats and liquids smoothly. This emulsification leads to a uniform texture, preventing separation of ingredients and resulting in a consistent crumb structure.

Tenderization

Interference with Gluten Formation: The fats in egg yolks can tenderize dough by interfering with gluten formation. This results in softer, more tender baked goods, which is particularly important for cookies and cakes.

In summary, eggs contribute significantly to the texture of baked goods by providing structure, leavening, moisture, richness, emulsification, and tenderness. Their multifunctional properties make them indispensable in baking.
