Preparation of Fish Skin Gelatin-Based Nanofibers Incorporating Cinnamaldehyde by Solution Blow Spinning

Abstract

Cinnamaldehyde, a natural preservative that can non-specifically deactivate foodborne showed antibacterial activity by direct diffusion and vapor release against Escherichia coli O157:H7, 26Salmonella typhimurium, and Listeria monocytogenes. Inhibition zones increased as cinnamaldehyde 27 ratio increased. Nanofibers showed larger inhibition effects than films prepared by casting method 28 when S. typhimurium was exposed to the released cinnamaldehyde vapor, although films had higher 29 remaining cinnamaldehyde than nanofibers after preparation. Lower temperature was favorable for 30 cinnamaldehyde retention, and nanofibers added with 10% cinnamaldehyde ratio showed the 31 highest retention over eight-weeks of storage. Results suggest that FSG nanofibers can be prepared 32 by SBS as carriers for antimicrobials. 33

Molecular Encapsulation of Cinnamaldehyde within Cyclodextrin Inclusion Complex Electrospun Nanofibers: Fast-Dissolution, Enhanced Water Solubility, High Temperature Stability, and Antibacterial Activity of Cinnamaldehyde

“…30 In the study of Liu et al, antibacterial fish skin gelatin-based NF incorporating cinnamaldehyde was fabricated to be used in controlled-release applications. 31 In another study, electrospun chitosan/poly-(ethylene oxide) mats including cinnamaldehyde having antibacterial activity against pseudomonas bacteria was engineered in order to be potentially used for alleviating nosocomial infections. 32 In a very recent study, electrospun fibrous film was developed to be used in food industry from the pea protein isolate-polyvinyl alcohol with cinnamaldehyde cooperation to obtain a material showing antibacterial activity against both Gram-positive and -negative bacteria.…”

Porous, Aligned, and Biomimetic Fibers of Regenerated Silk Fibroin Produced by Solution Blow Spinning

“…Analysis of the viscoelastic properties of RSF formulations is of interest since solution viscosity determines whether a droplet spray or continuous fibers are obtained, as it affects initial droplet shape and stability of the jet trajectory during SBS. 47 The viscosity measurements of RSF formulations of formic acid and the aqueous system at increasing concentrations are shown in Figure 1a,b. Both systems exhibited slightly different rheologies over the range of concentrations tested.…”

Antifungal and physicochemical properties of Ocimum essential oil loaded in poly(lactic acid) nanofibers

“…2015; Liu et al . 2018b). Previous reports have shown that the viscosity of the polymeric solution increases as a result of the incorporation of the constituents of the essential oil, and the fibre diameter is affected (Liu et al .…”

“…Mori et al (2015) showed that the addition of essential oil from candeia to the polymeric solution resulted in an increase in the average diameter of the nanofibres obtained; this fact corroborates the results obtained in this study. Studies suggest that the viscosity and surface tension of the solution are key parameters during the formation of the nanofibres, and the increase in the viscosity of the solutions is the result of the increase in the diameter of the nanofibres (Silva et al 2015;Liu et al 2018b). Previous reports have shown that the viscosity of the polymeric solution increases as a result of the incorporation of the constituents of the essential oil, and the fibre diameter is affected (Liu et al 2018a(Liu et al , 2018b, similarly to what was reported in this work.…”
