Common Desserts and Baked Goods
Egg whites are a foundational ingredient in many classic desserts and baked goods, prized for their ability to create volume, structure, and a light, airy texture. This is primarily achieved by whipping the whites into a foam that traps air.
Meringues and Macarons
- Meringue: These light, crisp confections are made by whisking egg whites and sugar until they form stiff, glossy peaks. They can be baked into nests for fillings or used as toppings for pies, like the classic lemon meringue pie.
- Macarons: The delicate shells of these popular French confections are made from an almond flour and egg white meringue base.
Cakes, Cookies, and Frostings
- Angel Food Cake: This famously light and fluffy cake is made with only egg whites and no egg yolks or butter, relying entirely on the whipped whites for its signature volume.
- Royal Icing: Often used for decorating cookies and cakes, this hard-drying icing is made with egg whites or meringue powder.
- Marshmallows: Some homemade and commercial marshmallows use egg whites to achieve their fluffy, light texture.
Unexpected Processed and Savory Foods
Egg whites aren't just for sweets; they serve many functional roles in processed and savory foods, often acting as a binder, leavening agent, or clarifying agent. These can be tricky to spot without carefully reading the ingredient list.
Sauces and Dressings
- Mayonnaise and Salad Dressings: While traditional mayonnaise uses egg yolks, some dressings and spreads, including some fat-free versions or egg white-only mayos, may incorporate egg whites as an emulsifier. Always check the label on creamy dressings like Caesar or tartar sauce.
- Foamy Cocktails: Many classic sour cocktails, like a whiskey or pisco sour, use an egg white to create a distinctively creamy foam top.
Processed Meats and Imitation Products
- Meatballs and Meatloaf: Egg whites can be used as a binder to hold the ground meat and other ingredients together, ensuring the final product doesn't fall apart during cooking.
- Imitation Meats and Surimi: Vegetarian meat substitutes, such as those that mimic chicken or crab, frequently use egg white as a binding and texturizing agent. Surimi, a fish paste found in imitation crab meat, often contains it as well.
Clarifying Agents and Finishes
Egg whites' ability to coagulate and capture impurities makes them useful as a clarifying agent in various beverages and broths.
- Consommés and Soups: A classic technique for creating a perfectly clear broth or consommé involves stirring in beaten egg whites, which form a raft that solidifies and collects impurities.
- Wine: Some winemakers use egg whites as a 'fining' agent to remove unwanted particles and clarify the wine.
- Breads and Pastries: An egg wash, often made with egg whites or whole eggs, is brushed on baked goods like bagels and burger buns to create a shiny, golden-brown glaze and help seeds stick.
Egg White vs. Plant-Based Alternatives
For those with egg allergies or following a vegan diet, understanding the functional differences between egg whites and common plant-based alternatives is key. The right substitute depends on the specific role the egg white plays in the recipe—binding, leavening, or moisture.
| Food Function | Egg White Use | Plant-Based Alternative | Notes on Substitution |
|---|---|---|---|
| Binding | Meatloaf, veggie burgers | Ground flaxseed mixed with water (flax egg) | Flax eggs add a nutty flavor and are best for dense dishes. |
| Foaming | Meringues, cocktails | Aquafaba (chickpea brine) | Aquafaba whips up similarly to egg whites for meringues and cocktails. |
| Leavening | Angel food cake, soufflés | Baking soda and vinegar mix | This substitution creates air bubbles for a light, fluffy texture. |
| Moisture | Some waffles, cakes | Mashed banana, unsweetened applesauce | Fruit purees add moisture but can also impart their own flavor. |
A Concluding Perspective on Egg Whites
Whether you have an allergy or simply wish to avoid them, egg whites are a prevalent ingredient in the modern food supply. Their functional properties, from foaming and gelling to binding and clarifying, make them invaluable to both home cooks and the industrial food sector. As many food allergy awareness groups point out, it is crucial to learn the different names of egg products on food labels to avoid exposure. Hidden sources are common, requiring vigilance when consuming pre-made and processed items. With the increasing availability of effective plant-based alternatives, navigating a diet free of egg whites is more manageable than ever before. Knowing the role the ingredient plays in a dish is the first step toward finding the perfect replacement.

Flavorings and Powders
- Artificial and Natural Flavorings: Sometimes, egg derivatives are used as stabilizers or carriers in artificial or natural flavorings. This means checking the ingredient list is necessary even for products where you wouldn't expect egg to be present.
- Baking Mixes: Many commercial baking mixes for cakes, pancakes, and brownies include powdered eggs to simplify the preparation process.
- Protein Powders: Some protein supplements and shakes, particularly those not labeled as vegan, use egg white powder as a protein source.
Other Surprising Products
- Coffee Drinks: Certain specialty coffee drinks with foamy toppings, like some cappuccinos, may contain egg whites or egg white powder to create the foam.
- Marzipan: Traditional recipes for marzipan, a sweet almond paste, sometimes incorporate egg whites.
- Candies: Some candies, including lollipops and nougat, can use egg whites as a binding agent.
Reading labels for egg whites
To ensure you are avoiding all forms of egg whites, it's essential to recognize the different ways they can be listed on an ingredient label. The FDA requires the term "egg" to appear on the label for regulated products, but manufacturers may list specific egg components or derivatives.
Ingredient Names Indicating Egg White:
- Albumen: Another name for egg white.
- Lysozyme: An enzyme found in egg white, used as a preservative.
- Ovalbumin, Ovomucin, Ovotransferrin: These are specific proteins found in egg whites.
- Globulin: A component of egg white protein.
- Surimi: A fish paste that can contain egg white.
- Avidin: A protein in egg white that can bind to biotin.
