lg egg whites
Egg whites are a lean source of complete protein containing all nine essential amino acids, with approximately 3.6 grams of protein per large egg white and negligible fat and carbohydrates. They contain lysozyme, a natural antimicrobial protein, and are rich in riboflavin and selenium.
About
Egg whites are the clear, viscous albumen that surrounds the yolk of a chicken egg, comprising approximately 90% water and 10% proteins, primarily ovalbumin, ovotransferrin, ovomucoid, and lysozyme. The white consists of four distinct layers of varying density and viscosity, ranging from the thin outer layer to the thick middle layer surrounding the yolk. Large eggs typically contain approximately 30-35 grams of white per egg. Egg whites transition from translucent to opaque white when heated to approximately 60-65°C (140-149°F), undergoing protein denaturation that creates their characteristic coagulated texture.
Culinary Uses
Egg whites serve as a critical binding, leavening, and emulsifying agent across global cuisines. They are essential for meringues, soufflés, mousses, and angel food cakes where their whipping capability creates stable foam structures. In Asian cuisines, particularly Chinese cooking, egg whites are used as a velveting agent for delicate proteins and in clear broths. They bind breading mixtures, clarify stocks and consommés, and serve as a glazing agent. Nutritionally concentrated and fat-free, they are valued in health-conscious cooking and sports nutrition applications, both cooked and in raw preparations like salads and smoothies when using pasteurized eggs.
