egg whites 2
Egg whites are an excellent source of high-quality, complete protein with minimal calories (approximately 17 calories per large egg white) and contain no fat or cholesterol. They also provide selenium, riboflavin, and other B vitamins.
About
Egg whites are the translucent, viscous albumen portion of a chicken egg, comprising approximately 90% water and 10% proteins, primarily ovalbumin. This component is separated from the yolk and used independently in cooking and baking. Egg whites contain no fat or cholesterol, distinguishing them from whole eggs, and are valued for their ability to form stable foams when whipped, a property resulting from the denaturation and reorganization of protein molecules at the air-liquid interface.
In their raw state, egg whites are clear and nearly colorless, becoming opaque and white upon cooking through protein coagulation. The texture transitions from liquid to solid or semi-solid depending on heat application and duration.
Culinary Uses
Egg whites serve as a versatile baking and cooking ingredient across global cuisines. In pastry work, whipped egg whites create meringues, soufflés, angel food cakes, and mousses through their foam-forming capacity. In Asian cuisines, particularly Chinese and French culinary traditions, they are used in batters for deep frying to create light, crispy coatings. Egg whites are also employed as binding agents in forcemeats and terrines, as a clarifying agent in consommés, and in cocktails such as sours and flips. Poached or soft-cooked egg whites serve as a protein-rich breakfast component.
