According to the invention, the problems of complex preparation process, low embedding transmission efficiency, poor dissolution and dispersibility of xanthophyll, low absorption and utilization rate and the like of the xanthophyll embedding carrier are solved. The preparation method of the Maillard reaction modified corn peptide loaded xanthophyll nanoparticles comprises the following steps: 1, preparing a chitosan oligosaccharide solution and a corn peptide solution; 2, adjusting the pH value of the solution; 3, preparing glycosylated corn peptide through Maillard reaction; 4, carrying out load combination on the glycosylated corn peptide and the xanthophyll; and 5, preparing the xanthophyll nanoparticles. The method has the advantages that 1, the embedding rate and the solubility of the lutein are effectively improved; 2, the stability and the dispersity of the xanthophyll nanoparticles are improved; the absorption and utilization rate is good, the nutritive value is high, and large-scale production is easy. The preparation method of the xanthophyll nanoparticles is simple in process and good in xanthophyll controlled release effect and has a targeted absorption function.

The application discloses praseodymium-neodymium oxide and a preparation method thereof. The preparation method comprises the following steps: 1) adding a praseodymium-neodymium chloride solution and ammonia water into an ammonium acetate solution in a parallel flow mode, performing solid-liquid separation after the reaction is completed, and obtaining a praseodymium-neodymium oxide precursor; 2) performing calcination on the praseodymium-neodymium oxide precursor, and obtaining praseodymium-neodymium oxide. The praseodymium-neodymium oxide has a porous sheet structure. The praseodymium-neodymium oxide with the porous sheet structure can be obtained by using the preparation method.
