unbeaten egg whites
Egg whites are an excellent source of high-quality, complete protein with minimal fat and no cholesterol, providing approximately 3.6 grams of protein per large egg white with only 17 calories. They contain trace amounts of selenium, magnesium, and potassium.
About
Egg whites are the clear, viscous albumen surrounding the yolk of a chicken egg (Gallus gallus domesticus), comprising approximately 60% of the egg's total weight. Chemically, they consist primarily of water (about 90%) and proteins, with trace amounts of minerals and glucose. Unbeaten egg whites retain their raw, liquid state and possess a neutral flavor with a subtle, slightly sweet undertone. The protein structure remains in its native, coagulated form until subjected to mechanical action or heat, which denatures and aligns the proteins to create foam or solid structures.
The quality and viscosity of egg whites vary with egg freshness; fresher eggs yield thicker, more cohesive whites, while aged eggs produce thinner, more runny whites. Commercial egg white products are also available as frozen, dried, or pasteurized liquid forms, though these differ slightly in functional properties from fresh unbeaten whites.
Culinary Uses
Unbeaten egg whites serve as a critical binding, coating, and coagulating agent across numerous culinary applications. In baking, they stabilize mousses, pavlovas, and meringues when whipped, and provide structure to cakes and soufflés when incorporated gently into batters. They function as a clarifying agent in stocks and consommés, and as a protective glaze for roasted meats and vegetables. In Chinese cuisine, egg whites are used raw or lightly poached in velvet marinades for silky-textured poultry and seafood. They are also employed as a traditional binder in forcemeats and terrines, and as a wash before breading or coating applications in fried foods.
