Wash the chicken under cold water and pat dry with paper towels. Place chicken in a food processor until finely chopped. Add the salt.
Lightly beat the egg whites in a small bowl until foamy. Fold the white into the mince.
Bring chicken stock to boil add the creamed corn. Dissolve the corn flour in a little water and add to the soup, stirring until mixture thickens.
Reduce heat and add the chicken mixture, breaking it up with a whisk. Allow to heat through, without boiling, for about 3 minutes. Season with soy sauce. Serve immediately.
