“…Figure 6 shows a comparison between the AO activity of PEO/AVE fibres and pure AVE fractions. Similar AO values were obtained for DPPH, ABTS and FRAP assays, indicating that the AO activity of AVE was maintained in a very high extent after the electrospinning process, ensuring the chemical integrity of AVE. Analogous results were obtained by Amna et al [121] for the encapsulation of capsaicin into polyurethane-based electrospun fibres. Sarkar et al [122] found a decrease in AO activity of honey components, compared to the non-encapsulated active sample after the production of PVA/honey electrospun fiber membranes.…”

Aloe Vera is an ancient medicinal plant especially known for its beneficial properties for human health, due to its bioactive compounds. In this study, nanofibers with antioxidant activity were successfully obtained by electrospinning technique with the addition of a natural Aloe Vera skin extract (AVE) (at 0, 5, 10 and 20 wt% loadings) in poly(ethylene oxide) (PEO) solutions. The successful incorporation of AVE into PEO was evidenced by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetric analysis (TGA) and antioxidant activity by 2,2-diphenyl-1-picrylhydrazyl radical scavenging (DPPH), 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging (ABTS) and ferric reducing power (FRAP) assays. The incorporation of AVE introduced some changes in the PEO/AVE nanofibers morphology showing bimodal diameter distributions for AVE contents in the range 10-20 wt%. Some decrease in thermal stability with AVE addition, in terms of decomposition onset temperature, was also observed and it was more evident at high loading AVE contents (10 and 20 wt%). High encapsulation efficiencies of 92%, 76% and 105% according to DPPH, FRAP and ABTS assays, respectively, were obtained at 5 wt% AVE content, retaining AVE its antioxidant capacity in the PEO/AVE electrospun nanofibers. The results suggested that the obtained nanofibers could be promising materials for their application in active food packaging to decrease oxidation of packaged food during storage.

“…62 Also a group of researchers determined that the antioxidant activity of capsaicin containing electrospun nanofibers (78%) was higher than that of capsaicin (70%). 63 In our study, the antioxidant activity of extract-loaded 5% CE P/WF (50:50) nanofibers had significantly higher antioxidant activity than others (p < 0.05). However, clove extract free nanofibers did not have any antioxidant activity.…”

In this study, clove extract loaded nanofibers consisting of pullulan and whey protein were produced by electrospinning method in order to improve antibacterial and antioxidant activity. Diameters of the produced nanofibers varied between 215.7 and 536.8 nm. Fourier Transform Infrared Spectroscopy (FTIR), X‐ray diffraction (XRD) and differential scanning calorimeter (DSC) results showed that there was a close interaction between the obtained nanofibers and clove extract. Although the antioxidant activity of the nanofibers varied between 1535 and 4174 μmol TE/g dm, the antioxidant activity of the clove extract loaded nanofibers tended to increase when compared to their polymer solutions. The total phenolic content of the nanofiber samples varied between 4.93 and 45.05 mg GAE/g dm. It has been determined that clove extract loaded nanofibers showed antibacterial activity against Staphylococcus aureus (ATCC29113) and Micrococcus luteus (NCIMB). As a result, it was seen that the addition of clove extract improved the antioxidant and antibacterial properties of the fibers and these fibers could be a potential coating and packaging material that could have a potential use in food preservation.

“…Capsaicin is an herbal active secondary metabolite from the alkaloid group with good antioxidant activity [62]. In a previous study, a significant increase was observed in the antioxidant activities of the films obtained by adding capsaicin to the polyurethane film [63]. In another study, the inhibition rate of DPPH increased from 31.72% in the control group to 94.40% by adding different amounts of capsaicin to chitosanbased films [64].…”

In the literature, the produced β-chitin samples are in powder or flake forms but there is no natural β-chitin based film. Also, the commercially available transdermal patches are produced from synthetic polymers. In this regard, we produced natural β-chitin-protein complex (CPC) film from the waste shells of Ensis spp. The obtained natural film was characterized by FTIR, TGA and SEM. Additionally, swelling, thickness, contact angle and antioxidant tests were done to learn more about the films. After production and characterization of the film, capsaicin, which is commonly used for pain relief was loaded into the film. The loading capacity was recorded as 5.79%. The kinetic models were studied in three different pH, then the results were fitted with Higuchi model with high correlation at pH 7.4. After considering all the obtained results, the capsaicin loaded CPC film may be an alternative candidate for transdermal patch instead of the synthetic ones.
