While Egg protein is generally considered nutritious, when powdered it is typically manufactured through spray drying. Though the eggs are typically pasteurized, egg protein powder is best served cooked to ensure that the avidin, a type of protein, has been deactivated. Avidin binds to biotin, a crucial B-vitamin. When this happens, biotin deficiency may occur and symptoms such as hair loss, skin problems, as well as neurological symptoms in adults like depression, may present.
Powdered egg protein powder can contain dangerous pathogens like Salmonella, too. This is especially true if the eggs were sourced from factory farms. Chickens in concentrated animal feeding operations often live in toxic and polluted environments so it’s no surprise these animals, and consequently their eggs too, end up carrying diseases and infections.
Traces of antibiotics, hormones and other pharmaceuticals may be present in the egg protein powder if the raw material utilized was sourced from factory-farmed eggs as well. Antibiotics in factory-farmed eggs are particularly a concern as it has been found to cause antibiotics-resistance in humans. These dangers are the reason scrutinizing where the eggs for the protein powder were sourced is crucial.
