  • Title: Development of a nanoparticle delivery system based on zein/polysaccharide complexes.
    Author: Li M, Yu M.
    Journal: J Food Sci; 2020 Dec; 85(12):4108-4117. PubMed ID: 33249573.
    Abstract:
    Zein, an alcohol-soluble protein in corn, can self-assemble into spherical nanoparticles, which makes it an ideal carrier material for the encapsulation of hydrophobic bioactive molecules. However, zein nanoparticles easily aggregate in water and are sensitive to enzymatic degradation in the digestive system. A strategy to overcome their limitations is the incorporation of polysaccharides as a second polymer layer that provides stability to zein nanoparticles. This review introduces the characteristics of zein as they relate to understanding the formation of zein/polysaccharide nanoparticles. Particular attention is paid to the preparation methods for the zein/polysaccharide nanoparticles, as well as to the morphological observation methods and detection mechanism. Moreover, the properties and applications of zein/polysaccharide nanoparticles are highlighted.
