The preparation method of a starch-based double-loaded functional nanoparticle includes: performing restrictive hydrolysis treatment on egg high-density lipoprotein using proteases to obtain the polypeptide; performing self-assembling on a mixed system containing the polypeptide and quercetin under the alkaline condition to form a micelle nanoparticle; performing covalent grafting reaction on a mixed system containing the micelle nanoparticle and anthocyanin under the alkaline condition to form a graft; and electrostatically compounding carboxymethyl dextrin with the graft to obtain the starch-based double-loaded functional nanoparticle. In the preparation method, raw materials derived from natural sources are used, and the self-assembled colloid nanoparticle with good properties can be obtained by adjusting the pH without any organic reagents. The obtained product has a nanoparticle size, has high antioxidant activity and stability against environmental stress, and can be widely applied to the fields of delivery of nutrients, stabilization of biologically active substances and the like.
