“…It was found that the average fiber diameter decreased with an increase of nisin content. The decrease of viscosity with the addition of nisin improves the molecular entanglement among the components and the stretching properties of the solution, resulting in a decrease of the electrospun fibers diameter (Neo et al 2013b). It is interesting to note that the diameters of the fibers obtained in this study were lower than those reported by Ahire and Dicks (2014), who obtained PDLA and PEO electrospun fibers loaded with nisin with diameters between 400 and 450 nm.…”

Most of antimicrobial peptides interact with food components decreasing their activity, which limit their successful incorporation into packaging material, functional foods and edible films. The aim of this work was to develop a nisin carrier. Nanofibers of amaranth protein and pullulan (50:50) loaded with nisin were obtained by electrospinning. The nanofibers morphology was determined by scanning electron microscopy and fluorescent microscopy. The molecular interactions were characterized by infrared spectroscopy, X-ray diffraction, differential scanning calorimetry, and thermogravimetric analysis. The nisin loading efficiency as well as the antimicrobial activity against Leuconostoc mesenteroides were evaluated. The micrographs of the obtained materials exhibited smooth and continuous fibers with no defects characterized by diameters between 124 and 173 nm. The FTIR analysis showed intermolecular interactions mainly by hydrogen bonding. The electrospinning process improved the thermal properties of the polymeric mixture displacing the Tm peak to higher temperatures and increasing crystallinity. The antimicrobial activity of nisin in broth and agar against L. mesenteroides was maintained after incorporation into fibers. The results presented an outlook for the potential use of protein amaranth nanofibers when incorporating antimicrobials as a food preservation strategy.

“…Among various approaches for preparation of nano-materials, electrospinning is one of the most attractive methods for its continuous fabricating capability and facile operating process (Kayaci & Uyar, 2012). Particularly, the electrospun fibers exhibit a large surface area to volume ratio due to the high porosity and nano to sub-micron structure, which is favorable for the sustained release of antimicrobial agent from the packaging film to the food surface (Neo et al, 2013). In the past few years, electrospinning has been well established in the fields of tissue engineering (Li, Laurencin, Caterson, Tuan, & Ko, 2002), wound dressing (Thakur, Florek, Kohn, & Michniak, 2008), enzyme immobilization (El-Aassar, 2013), and electrode materials (Dong, Wang, Hu, Yang, Qian, Ling, et al, 2013), etc.…”

“…GA and its derivatives including tannins and catechin are especially found in berries, citrus fruits, cereals, tea, wine and herbs [2]. Since it has antioxidant and antimicrobial activity, it is used as an additive in food, cosmetics and pharmaceutical industry [3][4][5][6]. However, it might easily oxidize which further leads to degradation.…”

Cyclodextrin-inclusion complexes (CD-ICs) possess great prominence in food and pharmaceutical industries due to their enhanced ability for stabilization of active compounds during processing, storage and usage. Here, CD-IC of gallic acid (GA) with hydroxypropyl-beta-cyclodextrin (GA/HPβCD-IC) was prepared and then incorporated into polylactic acid (PLA) nanofibers (PLA/GA/HPβCD-IC-NF) using electrospinning technique to observe the effect of CD-ICs in the release behavior of GA into three different mediums (water, 10% ethanol and 95% ethanol). The GA incorporated PLA nanofibers (PLA/GA-NFs) were served as control. Phase solubility studies showed an enhanced solubility of GA with increasing amount of HPβCD. The detailed characterization techniques (XRD, TGA and 1 H-NMR) confirmed the formation of inclusion complex between GA and HPβCD. Computational modeling studies indicated that the GA made an efficient complex with HPβCD at 1:1 either in vacuum or aqueous system. SEM images revealed the bead-free and uniform morphology of PLA/GA/HPβCD-IC-NF. The release studies of GA from PLA/GA/HPβCD-IC-NF and PLA/GA-NF were carried out in water, 10% ethanol and 95% ethanol, and the findings revealed that PLA/GA/HPβCD-IC-NF has released much more amount of GA in water and 10% ethanol system when compared to PLA/GA-NF. In addition, GA was released slowly from PLA/GA/HPβCD-IC-NF into 95% ethanol when compared to PLA/GA-NF. It was also observed that electrospinning process had no negative effect on the antioxidant activity of GA when GA was incorporated in PLA nanofibers.
