In recent years, development of biopolymeric nanofibers as an active biodegradable packaging system has attracted specific attention. The objective of this research was to develop zein-based electrospun nanofibers (NFs) incorporated with geraniol-loaded nanoliposomes (G-loaded NLPs). Geraniol was encapsulated into NLPs with an efficiency of 79.23%. The particle size and zeta potential of G-loaded NLPs were 121.50 nm and -38.30 mV, respectively. The successful loading of geraniol in the NLPs was approved by Fourier transform infrared (FT-IR) spectroscopy. The liposomal vesicles showed spherical shapes. G-loaded NLPs were added in the zein-based electrospun NFs at three different concentrations (0.25, 0.5, and 1%w/v). All NFs samples exhibited fibrillar structure. The increase of NLPs concentration enhanced the thermal stability of the NFs. However, the crystalline structure of zein NFs did not change by the addition of G-loaded NLPs. The highest surface hydrophobicity was related to the NFs containing 1% G-loaded NLPs. The mechanical parameters of NFs depend on the concentration of NLPs. The NFs incorporated with G-loaded NLPs showed inhibition activity against four foodborne pathogenic bacteria (, , , and ) with an inhibition zone of 4.5-22 mm. Moreover, the α-diphenyl-β-picrylhydrazyl (DPPH) scavenging activity of NFs samples was located at the range of 20%-48%. These findings represent the Efficiency of the G-loaded NLPs for use as bioactive compound in the zein-based NFs as an active packaging material.
近年来，生物聚合物纳米纤维作为一种活性可生物降解包装系统的发展引起了特别关注。本研究的目的是开发含有负载香叶醇的纳米脂质体（G-负载NLP）的玉米醇溶蛋白基电纺纳米纤维（NFs）。香叶醇被封装到NLP中的效率为79.23%。G-负载NLP的粒径和zeta电位分别为121.50 nm和-38.30 mV。通过傅里叶变换红外（FT-IR）光谱证实了香叶醇在NLP中的成功负载。脂质体囊泡呈球形。将G-负载NLP以三种不同浓度（0.25、0.5和1%w/v）添加到玉米醇溶蛋白基电纺NFs中。所有NFs样品均呈现纤维状结构。NLP浓度的增加提高了NFs的热稳定性。然而，添加G-负载NLP并没有改变玉米醇溶蛋白NFs的晶体结构。最高的表面疏水性与含有1%G-负载NLP的NFs有关。NFs的机械参数取决于NLP的浓度。含有G-负载NLP的NFs对四种食源性病原体（、、和）表现出抑制活性，抑制圈为4.5-22 mm。此外，NFs样品的α-二苯基-β-苦味酰基肼（DPPH）清除活性在20%-48%的范围内。这些发现表明G-负载NLP作为活性包装材料在玉米醇溶蛋白基NFs中用作生物活性化合物的有效性。
