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.

The present invention provides a soybean oligopeptide with low allergenicity and little bitterness and its preparation method and application. The preparation method includes the following steps: 1) mixing a soybean protein powder with water to obtain a soybean protein solution, and then performing thermal denaturation on the soybean protein solution, to prepare a denatured protein solution; 2) adjusting pH value of the denatured protein solution to 6-9, and then adding a neutral protease and papain to conduct a first enzymolysis, to obtain a first enzymatic hydrolysate; 3) adding an alkaline protease and a flavor protease into the first enzymatic hydrolysate to conduct a second enzymolysis, and after performing enzyme inactivation, to obtain a second enzymatic hydrolysate; and 4) centrifuging the second enzymatic hydrolysate, and performing membrane filtration on centrifuged supernatant liquid, to obtain the soybean oligopeptide with low allergenicity and little bitterness.
