The Effects of Citric Acid Crosslinking on Fabrication and Characterization of Gelatin/Curcumin-Based Electrospun Antioxidant Nanofibers

Nanofibers, produced through the novel method of electrospinning, have a high ratio surface area to volume, which allows them different optical, electrical, thermal, and mechanical properties than macroscale materials. In this study, it was aimed produce nanofibers with gelatin curcumin. The effects concentration crosslinking citric acid on characteristics electrospun were studied. Gelatin film containing neither nor curcumin used as control. Solutions evaluated by solution conductivity, color analysis, rheological properties. Obtained characterized morphological analysis (SEM), antioxidant activity (AA), thermal (TGA, XRD, DSC), water vapor permeability (WVP), Fourier transform infrared (FTIR) analysis. It found that functional groups not changed significantly but some degree seen, indicated changes in AA, crystallinity, etc. Improvement activities highest for films (32%). melting temperature (78 °C) WVP (2.365 × 10−10 gm−1 s−1 Pa−1) seen crosslinked 0.5% acid. 1% showed lowest crystallinity (1.56%). concluded even though might prove be stable agent protein (gelatin), contributed nature films, along These are promising candidates applied cut fruits, reduce loss oxidation hence extend their shelf lives.
