摘要： Hydrogen peroxide (H2O2) was used to modify a natural polymer, sesbania gum (SG), to prepare oxidized sesbania gum (OSG) with the aim of investigating the physicochemical properties, antimicrobial activity of polyethylene oxide (PEO), OSG, and epsilon-poly(lysine) (epsilon-PL) composite fibre membranes and their applications in freshcut mango preservation. The PEO/OSG/epsilon-PL composite fibre membranes were successfully prepared via solution blow spinning (SBS) technology. The results of a series of characterizations revealed that epsilon-PL was successfully loaded into the fibrous membranes, exhibited good biocompatibility, and epsilon-PL was better encapsulated, with the membranes. The hydrophilicity, thermal stability, mechanical properties, and flexibility of the fibrous membranes were improved, and the water vapour transmission rate was reduced with the epsilon-PL content. In vitro bacterial inhibition experiments revealed that PEO/OSG/epsilon-PL fibre membranes with more than 2 wt% added epsilon-PL effectively inhibited the growth of E. coli and S. aureus. Fruit preservation experiments showed that PEO/ OSG/epsilon-PL fibre membrane could reduce weight loss, inhibit microbial growth, and delay quality deterioration of fresh-cut mango. In addition, the PEO/OSG/epsilon-PL fibre membrane showed high biodegradability. These results show that the PEO/OSG/epsilon-PL composite fibre membrane prepared by SBS has application potential as an active packaging material.
