“…This slight increase in the fiber diameters can be related to the relatively high amount of CDs that aggregated during electrospinning and resulted in destabilization of the electrified jet. The present results agree with the reports of (Topuz & Uyar, 2019), concluding that at low hydroxypropyl-β-CD/Laponite the fibers do not present any significant change in diameter and shape while at high concentrations the nanocomposite nanofibers from a non-polymeric system diameter decreases and also generates aggregates. Furthermore, changes in the solution properties such as viscosity or conductivity may cause variations in the electrospun morphologies.…”

Oregano essential oil (OEO) has good antioxidant and antimicrobial activity and its incorporation into food packaging is challenging because of its intense flavor, high volatility and instability, and insolubility in aqueous systems. Additionally, the sensory perception of EO can be changed as a consequence of oxidation, heating, volatilization or chemical interactions. Cyclodextrins (CDs) can be used to avoid these inconveniences because they are able, due to their peculiar chemical structure, to encapsulate hydrophobic molecules such as OEO improving its aqueous solubility and reducing its volatility. In this work, kneading (KM) and freeze-drying (FDM) methods were evaluated to encapsulate OEO in two cyclodextrins types (α-CD and γ-CD). After, the α-CD:OEO and γ-CD:OEO inclusion complexes (ICs) were included in poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) electrospun fibers by electrospinning and annealed for film formation. Results showed that the encapsulation efficiency of oregano essential oil is influenced by both the encapsulation methods and the cyclodextrin type. The antimicrobial and antioxidant activity of the α-CD:OEO and γ-CD:OEO inclusion complexes were higher compared with pure OEO. The optimal concentration of α-CD:OEO inclusion complexes and γ-CD:OEO inclusion complexes for homogeneous and continues films formation was 15 and 25 wt%, respectively. At these concentrations, the films showed a strong antimicrobial and antioxidant activity, up to 15 days. In addition, the mechanical properties of the films were also improved (Young's modulus + 35%). In conclusion, this work shows that the encapsulation of CD:OEO inclusion complexes by electrospinning into PHBV polymeric matrix opens a new path in the development of bioactive packaging materials using EOs.

“…In general, the electrospinning process involves a polymer that generates the carrier matrix consisting of continuous nanofibres, in which the presence of a network of high molecular weight facilitates the formation of a stable jet during electrospinning. However, in the last decade research has been made on electrospinning of polymer-free materials with functional molecules for other new applications, such as phospholipids [6], ammonium gemini surfactant [7], cyclodextrin derivatives [8] and tannic acid [9].…”

This research aimed to obtain biocompatible and antimicrobial nanofibres based on concentrated collagen hydrolysate loaded with thyme or oregano essential oils as a natural alternative to synthesis products. The essential oils were successfully incorporated using electrospinning process into collagen resulting nanofibres with diameter from 471 nm to 580 nm and porous structure. The presence of essential oils in collagen nanofibre mats was confirmed by Attenuated Total Reflectance -Fourier Transform Infrared Spectroscopy (ATR-FTIR), Ultraviolet–visible spectroscopy (UV–VIS) and antimicrobial activity. Scanning Electron Microscopy with Energy Dispersive Spectroscopy analyses allowed evaluating the morphology and constituent elements of the nanofibre networks. Microbiological tests performed against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Candida albicans showed that the presence of essential oils supplemented the new collagen nanofibres with antimicrobial properties. The biocompatibility of collagen and collagen with essential oils was assessed by in vitro cultivation with NCTC clone 929 of fibroblastic cells and cell viability measurement. The results showed that the collagen and thyme or oregano oil composites have no cytotoxicity up to concentrations of 1000 μg·mL−1 and 500 μg mL−1, respectively. Optimization of electrospinning parameters has led to the obtaining of new collagen electrospun nanofibre mats loaded with essential oils with potential use for wound dressings, tissue engineering or protective clothing.

“…The precise scanning electron microscope images in Figure 9 indicated that the CEO increased the nanofiber diameter when β-CD was available in the structure. The CPVA/CEO (1.5 mL)/β-CD nanofibrous films had a water-contact angle of ≈90°, thus increasing their hydrophilicity, as shown in Figure 10 [ 139 , 140 , 141 ]. Moreover, Figure 11 shows that when β-CD was added to the PVA/CEO solution, the fibers showed the zone of inhibition against Escherichia coli and Staphylococcus aureus .…”

Essential oils prevent superbug formation, which is mainly caused by the continuous use of synthetic drugs. This is a significant threat to health, the environment, and food safety. Plant extracts in the form of essential oils are good enough to destroy pests and fight bacterial infections in animals and humans. In this review article, different essential oils containing polymeric nanofibers fabricated by electrospinning are reviewed. These nanofibers containing essential oils have shown applications in biomedical applications and as food-packaging materials. This approach of delivering essential oils in nanoformulations has attracted considerable attention in the scientific community due to its low price, a considerable ratio of surface area to volume, versatility, and high yield. It is observed that the resulting nanofibers possess antimicrobial, anti-inflammatory, and antioxidant properties. Therefore, they can reduce the use of toxic synthetic drugs that are utilized in the cosmetics, medicine, and food industries. These nanofibers increase barrier properties against light, oxygen, and heat, thereby protecting and preserving the food from oxidative damage. Moreover, the nanofibers discussed are introduced with naturally derived chemical compounds in a controlled manner, which simultaneously prevents their degradation. The nanofibers loaded with different essential oils demonstrate an ability to increase the shelf-life of various food products while using them as active packaging materials.
