This application relates generally to the processing of egg protein isolates for use in various food, sports nutrition and nutraceutical applications, methods of making egg protein isolates, and apparatus for making egg protein isolates. More particularly, the application relates to a method of deflavoring egg products and concentrating the protein content to greater than or equal to 92% dry basis protein. Deashing technologies can be used to produce egg protein isolates which can give egg additional tools to compete in the sports and nutrition markets dominated by whey and milk protein isolates.
