Homemade egg-white powder: drying is not a verified safety process

Removing moisture from raw egg whites does not by itself demonstrate that Salmonella has been controlled. A powder intended for an uncooked shake needs an appropriate food-safety basis.

Food safety depends on more than texture

FDA advises thorough cooking of eggs and use of treated shell eggs or pasteurized egg products when a recipe will be served raw or undercooked. A dry appearance is not evidence that a home process delivered an effective pathogen-control step. [1]

The cited guidance does not validate a particular home dehydration temperature, time or storage life for egg-white powder. It therefore cannot support a promise that a homemade batch is safe for an uncooked smoothie. [1]

Use an appropriate product for the intended preparation

For a preparation that will not be thoroughly cooked, choose an appropriately pasteurized egg product and follow its storage and use instructions. Do not assume a homemade substitute has the same treatment history as a commercial product. [1]

A protein calculation and a microbiological safety assessment are different tasks. Even an accurate estimate of protein per spoonful cannot establish that pathogens were removed. [1]

Powdered does not mean pasteurized

Imagine raw whites are dried until brittle and ground into powder. The change in form alone does not document Salmonella control or establish how long the powder may safely be stored.
