The effectiveness of tannic acid as antimicrobial and wound healing for burns have been shown for a century; however, uncontrolled target dosage may result in undesirable side-effects. Remarkably, tannic acid polyphenols compounds crosslinked with polymeric materials produce a strong composite containing the beneficial properties of this tannin. However, investigation of the crosslink structure and its antibacterial and regenerative properties are still unknown when using nanocellulose by mechanical defibrillation; additionally, due to the potential crosslink structure with chitosan, its structure can be complex. Therefore, this work uses bleach kraft nanocellulose in order to investigate the effect on the physical and regenerative properties when incorporated with chitosan and tannic acid. This film results in increased rigidity with a lamellar structure when incorporated with tannic acid due to its strong hydrogen bonding. The release of tannic acid varied depending on the structure it was synthesised with, whereas with chitosan it presented good release model compared to pure cellulose. In addition, exhibiting similar thermal stability as pure cellulose films with antibacterial properties tested against S. aureus and E. coli with good metabolic cellular viability while also inhibiting NF-κB activity, a characteristic of tannic acid.

“…Polymer intermolecular crosslinking improves a film’s mechanical and hydrophobic properties and creates integrated complex networks by forming chemical bonds (intramolecular or intermolecular) with molecular polymer chains [ 21 , 22 , 23 ]. As a low-toxic natural crosslinking agent for both chitosan and gelatin, genipin could be an ideal choice for making crosslinked chitosan/gelatin-based films [ 24 , 25 ].…”

Functional food packaging films were prepared using a binary mixture of chitosan and gelatin through crosslinking with genipin and hybridization with rosemary essential oil and quercetin. The mixture of chitosan and gelatin produced the compatible film, and the added fillers also showed good compatibility. The physical properties of the chitosan/gelatin film were not greatly affected by crosslinking with genipin, and the functionality of the composite film was increased by the addition of rosemary essential oil and quercetin. The bioactive additives did not significantly affect the hydrophobicity and water vapor barrier properties of the chitosan/gelatin film but significantly changed the color, while the mechanical and thermal properties were slightly affected. The addition of these functional fillers significantly improved the UV protection, antioxidant, and antibacterial properties of the chitosan/gelatin film. Therefore, the novel chitosan/gelatin film with genipin crosslinking and the integration of rosemary essential oil and quercetin is considered to have high potential for applications in active food packaging.

“…FC-C films showed the highest DPPH and ABTS activity because of curcumin and the active antioxidant biopolymer, chitosan. The hydroxyl and amino groups of chitosan interacted with free radicals and exhibited the radical scavenging activity (Roy et al, 2021). In addition to this, antioxidant activity of curcumin was originated from phenolic hydroxyl group and methylene group of β-diketone moiety (Priyadarsini et al, 2003).…”

The effects of crosslinking agents on faba bean flour–chitosan‐curcumin films and their characterization

Although glutaraldehyde (GLU) has been frequently preferred to improve some characteristics of bio-degradable food packages, it is regarded as a hazardous chemical.Therefore, in this study, the possibility of replacement GLU with citric acid (CA) a non-toxic compound was questioned in a film formation. Different ratios of GLU and CA on faba bean flour, chitosan, and curcumin film were examined. To determine the most favorable film composition, water solubility (WS), swelling degree (SD), water contact angle (WCA), water vapor permeability (WVP), and mechanical properties of the films were examined. In addition, the effects of crosslinking agent and their ratios on crystallinity (XRD), thermal properties (DSC and TGA), and antioxidant activity (DPPH and ABTS) were also studied. Time Domain Nuclear Magnetic Resonance (TD-NMR) relaxometry was also employed to explain distribution and mobility of the protons in faba bean flour, chitosan, and curcumin films. At the end of the analysis, it was concluded that CA and GLU reduced SD by 75% and 13% compared to the films without cross-linker, respectively. Incorporation of crosslinking agent increased the WCA from 77.22 to 99.41 and caused formation of more hydrophobic surfaces.Increasing both crosslinking ratios restricted the permeance drastically which was more than 110%. Furthermore, the lowest WVP was measured for the films containing CA at 1.5% w/v ratio (FC-1.5C). While GLU improved the tensile strength (TS) of the film, lower elongation of the films caused formation of brittle character which limited the utilization of the films. At the end of the analysis, it was concluded that FC-1.5 had more feasible character with respect to the other films and CA was suggested as a crosslinking agent instead of GLU for faba bean-chitosan films.
