Summary:A method for extracting IgY (γ-livetin) from yolk is disclosed, which comprises the following steps: (A) providing a buffer solution, a yolk sample, and an inorganic salt solution; (B) diluting the yolk sample with the buffer solution to obtain a mixture, stirring the mixture for a predetermined time, and performing a centrifugation on the mixture to obtain a supernatant; and (C) adding the inorganic salt solution into the supernatant to salt out IgY, wherein a pH value of the buffer solution is in a range from 4.6 to 5.4, a salt concentration of the buffer solution is in a range from 0.05 M to 0.15 M, and a saturation degree of the inorganic salt solution is in a range from 30% to 60%.
