聚己内酯-槲皮素纳米纤维膜的制备及其抗菌性能研究
Preparation and Antibacterial Properties of Polycaprolactone-Quercetin Nanofiber Membrane
摘要
Abstract
To extend the post-harvest shelf life of fruits and vegetables and prevent them from spoilage and deterioration due to microbial invasion,polycaprolactone-quercetin nanofiber membranes were prepared using electrospinning technology.The results showed that the nanofiber membranes exhibited excellent mechanical properties and antioxidant activity.The tensile strength,elongation at break,and DPPH radical scavenging rate of the membranes were(3.65±0.51)MPa,(131.13±5.04)%,and(80.13±0.23)%,respectively.When the addition amount of quercetin reached 6%,the antibacterial rate against Escherichia coli and the antibacterial rate against Staphylococcus aureus reached 99.63%and 99.64%,respectively.The practical application of the nanofiber membranes was evaluated by the storage experiment with millennium cherry toma-toes.Compared with commercially available polyethylene(PE)films,the membrances could significantly extend the storage period of millennium cherry tomatoes by 6 days.This indicates that the degradable polycaprolactone-quercetin nanofiber membranes can effectively inhibit the growth of foodborne pathogenic bacteria and can be used as food packaging materials to extend the shelf life of tomatoes.关键词
