Abstract

In this study, bioactive fibers were produced using polyvinyl alcohol (PVA), gelatin and pine honey by using electrospinning method. The influence of honey content (0–15 wt%) on the infrared spectrum, morphology, average diameter, surface wettability and antioxidant activity of the electrospun fibers was evaluated. The Fourier Transform Infrared spectrum showed the successful incorporation of honey to the fibers. Electrospun PVA/gelatin/honey nanofibers were successfully obtained with average diameters ranging from 299 ± 105 nm to 494 ± 192 nm. Increasing the honey content caused an increase in the fiber diameter. The values of the water contact angles of the fibers were increased upon the addition of pine honey. Among the fibers, the 10 wt% honey-loaded fiber exhibited a high antioxidant capacity, which was monitored using DPPH radical scavenging, β-carotene-linoleic acid and cupric reducing antioxidant capacity assays. In view of these results, the PVA/gelatin/honey fibers can be potential candidates for biomedical and active food packaging applications.

摘要

在这项研究中，生物活性纤维是通过静电纺丝法使用聚乙烯醇（PVA），明胶和松树蜜制成的。评估了蜂蜜含量（0-15 wt％）对电纺纤维的红外光谱，形态，平均直径，表面润湿性和抗氧化活性的影响。傅立叶变换红外光谱显示蜂蜜已成功掺入纤维中。已成功获得电纺PVA /明胶/蜂蜜纳米纤维，平均直径范围为299±105 nm至494±192 nm。蜂蜜含量的增加导致纤维直径的增加。添加松子蜂蜜后，纤维的水接触角值增加。在这些纤维中，载有10 wt％蜂蜜的纤维表现出较高的抗氧化能力，这可以通过DPPH自由基清除剂进行监测，β-胡萝卜素-亚油酸和铜还原抗氧化能力的测定。鉴于这些结果，PVA /明胶/蜂蜜纤维可以成为生物医学和活性食品包装应用的潜在候选者。
