egg white powder means: You can use it in almost all recipes that require egg white. This produces a stable, high-volume egg white foam that can be used in angel food cakes and chiffon pie, as well as divinity. You can use egg white powder to make uncooked food such as buttercream frosting and marzipan, or for foods that are light cooked pie meringues. It is heat-treated so it meets USDA salmonella standards. (in Cooking Dictionary)
