Eggs are natural foods with high nutritional benefits providing an inexpensive and low calorie source of high quality protein and several important nutrients. Among various components, ovalbumin from the egg white and IgY antibodies from the egg yolk have a high applicative potential.

The opportunity exists to use the egg white as a source of several valuable proteins, the yolk as a source of proteins and lipids, and the shell as a source of calcium and collagen
