Liquid egg whites are the clear, viscous part of an egg that surrounds the yolk. They are primarily composed of water and proteins, making them a popular choice for those looking to increase their protein intake without the added fat and cholesterol found in egg yolks. Liquid egg whites are often sold in cartons and can be used in various recipes, including omelets, meringues, and protein shakes. These egg whites are pasteurized, which means they have been heated to kill any harmful bacteria, making them safe to consume raw. They are a convenient option for cooking and baking, as they eliminate the need to separate the yolk from the white.
