Abstract: The development trend on research and exploitation of the bioactive substances in eggs was analyzed. The higheffective extraction technologies and biological active products exploitation techniques were then reviewed. The majorcontents and technologies were introduced in the paper as well. Many products such as egg yolk lecithin, egg white lysozyme,high F value oligopeptide, IgY as well as biological Calicium were extracted by supercritical fluid extraction, membraneultrafiltration, chromatography, enzyme and supermicro techniques. The natural substances could be used not only to providematerials, additives and functional factors for the third generation functional food, but also to enhance eggs value and toaccelerate the development of egg industry in China.
