It is an important means to improve the solubility, stability and bioavailability of nutrients by the design and construction of nanoparticles using protein and polysaccharides. So far, the problem of low loading rate, burst release and unclear release mechanism is not conducive to the effective delivery and utilization of nutrients. Base on the particular structure and self-assembly characteristics of zein, the construction of hollow zein/chitosan nanoparticle was put forward, in which the hollow structure could improve the loading rate and slow release of the guest molecules. First of all, hollow zein/chitosan nanoparticles were prepared by sacrifice template method and nonsolvent induce phase separation method. Secondly, solid zein/chitosan nanoparticles as control, the characterization and properties of hollow zein/chitosan nanoparticles were analyzed. The properties of the delivery system were studied and the assembly mechanism was elucidated. Finally, curcumin was used as a model to study the loading rate and elucidate the mechanism of the release of nutrients from the hollow zein/chitosan nanoparticle. This project provides a theoretical basis for enriching nano nutrient delivery system, and has important guiding significance for the application of nanotechnology in food science.
