| Abstract_FL | In this study,zein-quercetin(Zein-Q)nanoparticles were prepared and the effects of sophorolipids(SL)on the structure of Zein-Q nanoparticles were evaluated based on the combination of scanning electron microscopy,Fourier infrared spectroscopy and fluorescence spectroscopy.Their antioxidant and antibacterial properties were analyzed as well.The results showed that Zein-Q nanoparticles were spherical with an average particle size of 128 nm,the encapsulation efficiency and loading capacity were separately 25.8％±1.28％and 3.98％±0.24％,respectively,and its scavenging ability on DPPH and ABTS+.were 76.8％±0.9％and 65.4％±1.2％.The addition of sophorolipids resulted in forming nanoparticles with good dispersion.The structural characteration results showed that sophorolipids were coated with the outer layer of zein-quercetin nanoparticles driven by the interaction of hydrogen bonding and electrostatic interaction,forming a spherical core-cell structure with a larger particle size.At Zein-Q∶SL=3∶4,the encapsulation efficiency and loading capacity of composite Zein-Q-SL nanoparticles were increased to 73.6％±1.80％and 7.98％±0.41％,respectively.The antioxidant activity of zein-quercetin nanoparticles was enhanced,which showed that the scavenging ability of composite Zein-Q-SL nanoparticles on DPPH and ABTS+·reached 88.8％±1.0％and 78.6％±1.5％,respectively.In addition,the composite Zein-Q-SL nanoparticles showed a good inhibitory activity against Escherichia coli and Staphylococcus aureus.Thus,it can be concluded that biosurfactant sophorolipids have potential to be excellent modifier for enhancing the structural stability and activity of zein-quercetin nanoparticles. |
