tion from egg yolk with ethanol followed by hexane deoiling and acetone precipitation at 160℃ for 10 min. The purity of the extracted egg yolk PL was 95.2±3.0％ 4) . Nielsen reported solid-phase extraction of PL from heatcoagulated egg yolk by acetone-ethanol organic solvents. The yield and purity of PL were 15％ and 85％, respectively 5) . Wang and coworkers developed a simultaneous texturization and organic solvent extraction technique to extract PL from liquid egg yolk using butanol and ethanol solvents. A total PL yield of 78％ was obtained using 95％ ethanol solvent 6) . Su and co-workers used only ethanol to effectively separate phospholipids, triacylglycerol, and cholesterol from fresh egg yolk. The purity of the PL was 51.47％ 7) . Xie and co-worker investigated the profiling of egg yolk lipids obtained by an ultrasound-assisted isopropanol extraction method; a total PL content of 28％ was extracted from egg
