Many of the powdered Egg Substitutes are egg-free and are produced from ingredients such as starch, yeast extract, soy flour, wheat gluten, gum, artificial flavorings, and coloring that simulate the texture and flavor of eggs. They can be prepared by simply adding water to the powdered mixture. It is common to use a ratio of mixing 1 tablespoon of the Egg Substitute with 3 tablespoons of water for each egg to be replaced.
Liquid Egg Substitutes are packaged and sold as refrigerated or frozen food items and can often be prepared right from the package. Both the liquid and powdered substitutes are used in cooking and some are suitable for scrambling and for preparing omelets as well as other egg dishes. Like all other uncooked egg products, both the liquid and powdered Egg Substitutes are pasteurized.
