half one egg white
Egg whites are protein-rich (approximately 3.6 grams per large egg white) and fat-free, containing all nine essential amino acids. They are also a source of B vitamins, particularly riboflavin and selenium.
About
Egg white, also known as albumen, is the clear, viscous liquid component of a chicken egg that surrounds the yolk. Composed primarily of water (approximately 90%) and proteins, egg white lacks fat and cholesterol, making it distinct from the yolk. A half egg white represents a portion measurement equal to approximately 15 grams or one tablespoon. Egg whites coagulate when heated, transitioning from transparent to opaque, and can be whipped to form stable foam structures due to their protein content, particularly ovalbumin, ovotransferrin, and lysozyme.
Culinary Uses
Egg whites are utilized across culinary applications for their binding, leavening, and emulsifying properties. In baking, they create volume and structure in cakes, meringues, and mousses through mechanical aeration. Smaller portions, such as a half egg white, serve specific functions: as a binder in meat preparations and forcemeats, as a clarifying agent in consommés, or as an adhesive for breading. They are also employed in cocktails to create silky mouthfeel and foam. The protein denaturation during cooking makes egg whites valuable for creating custards, glazes, and protein-enriched preparations.
