The present invention relates to methods for the separation of various components from eggs. More particularly, the present invention relates to methods for the separation of proteins and lipids from eggs, including technical eggs (inedible) or edible eggs, yolks or whites, which comprises cross-linking the lipids of eggs with a cross-linking reagent. In an embodiment, the method includes separating the proteins from the cross-linked lipids. In an embodiment, the method includes the separation of various components associated with the cross-linked lipids. The methods disclosed herein allow for the isolation of multiple different components from the egg in an efficient, cost-effective manner without compromising the recovery process of the components or their subsequent utility in various applications or compositions. The compositions and isolated components obtained by the methods of the invention can be used in pharmaceutical, medical, nutritional, cosmetic or health applications.
