The invention provides a two-step decolorization method for phospholipid. The method comprises the following steps of: dissolving the phospholipid by using n-hexane as a solvent, adding a proper amount of hydrogen peroxide into the mixed phospholipid for oxidation and decolorization, and removing most pigment; and performing vacuum heating to remove un-reacted hydrogen peroxide and solvent, adding n-hexane to dissolve the phospholipid in a certain ratio, adding chromatography silica gel in a certain ratio, reacting with stirring, adsorbing peroxide, impurities and partial pigment in the phospholipid, filtering, desolventizing, and thus obtaining decolorized phospholipid. By adopting two-step decolorization, on the premise that the decolorization effect is ensured, the consumption of the hydrogen peroxide is reduced by over 30 percent, and the oxidation degree of the phospholipid in the decolorization process is effectively reduced; and by the adsorption effect of the silica gel, the acid value and the peroxide value of the phospholipid are further reduced, the transparency of the phospholipid is improved, and the quality of the product is effectively improved.
