The invention discloses a method for preparing egg yolk lecithin by adopting a two-step subcritical extraction technology, and belongs to the technical field of subcritical fluid extraction. According to the method, frozen egg yolk gel is used as a raw material, egg yolk powder is obtained through dilution, homogenization, centrifugation and spray drying, then the two-step subcritical extraction technology is adopted for preparing the egg yolk lecithin, solvent residues are avoided, the yield of lecithin in the obtained product is as high as 92.7%, the purity is as high as 95.8%, and the egg yolk lecithin can be directly used for medicines, food and health care products. According to the method, the extraction temperature and pressure are mild, protection of high-value components such as DHA, carotenoid and folic acid in a by-product egg oil is facilitated, and the application potential in medicine and food industries is huge; and meanwhile, another obtained by-product natural antibody egg yolk immune globulin has high helicobacter pylori resisting activity, and can effectively treat diseases such as gastric ulcer. Therefore, egg yolk resources can be fully utilized, and the comprehensive utilization value of the egg yolk is improved.
