Powdered eggs are particularly popular amongst campers, hikers, survivalists and preppers. But what exactly are powdered eggs? Well, to put it simply, powdered eggs are eggs that have been dehydrated and turned into an easy-to-store powder. Fresh eggs, which are obviously very tasty and also rich in protein, need to be refrigerated properly and quickly in order to prevent them from spoiling. If you’re in an emergency situation or if you’re camping somewhere fairly remote, then it’s entirely impractical to consider adding fresh eggs to your diet.

However, by dehydrating the eggs, you can eliminate any concerns regarding spoilage. Since they’re dehydrated, they can last for an incredibly long stretch of time—in fact, if stored in a cool, dry environment within a properly sealed container, powdered eggs can actually last a decade or more. Also, by making the eggs into a powder, they become easier to transport (say in backpack) and they’re also even easier to mix in with other foods or liquids—for instance, you can add milk, salt and water to powdered eggs to make some fast-and-easy scrambled eggs.

There are many different varieties of powdered eggs, which are designed to cater to particular tastes and diets. For example, some brands offer powdered eggs that are made from both yolk and egg whites, while others feature only egg whites or the yolks. In fact, many restaurants prefer to use powdered eggs over fresh eggs, mainly because when compared to buying fresh eggs in bulk, powdered eggs are far cheaper and have a much longer shelf life.

Like fresh eggs, powdered eggs are protein-rich, and they can also be used for just about any dish that calls for eggs (such as pies or meringues). Some brands also add extra flavoring to the powdered eggs to really ratchet up the taste factor. All in all, because powdered eggs are easy to transport, have an extended shelf life and they’re rich in protein, it’s no wonder why preppers and campers have been using powdered eggs for years. In fact, powdered eggs were especially popular during World War II, when the U.S. government needed to deliver large quantities of eggs to troops around the world, and they needed to ensure that the eggs could be transported quickly in bulk and could last during both storage and transit. In short, if you’re in need of a food item for your camping or emergency kit that’s packed with protein and will last for a decade or more, then consider picking up a container of powdered eggs.
