“…This can be attributed to the increase in the electrical conductivity of the Gt solution with the TA integration. 23 As compared to this, incorporation of HPO and VAP to the solution resulted in a rise in the mean fiber diameter (p < 0.05). This might be related to the action of HPO and VAP on reducing the electrical conductivity of Gt solutions, which increased the size of the fibers.…”

“…With the addition of TA in the Gt nanofibers, their size was significantly decreased ( p < 0.05). This can be attributed to the increase in the electrical conductivity of the Gt solution with the TA integration .

“…7,39 TA causes the death of bacteria by attacking the bacterial cell membranes through hydrophobic−hydrophobic interactions, which result in the breakdown of the membrane and the release of essential components from the bacterial cells. 23 The inhibition zones around the Gt−TA, Gt−TA−HPO, and Gt− TA−HPO−VAP nanofibers were not significantly different against E. coli and S. aureus (p < 0.5).…”

Recent studies in wound dressing applications offer new therapies to promote the wound healing process. The main strategy of this study is to combine the traditional perspective of using medicinal oils with polymeric scaffolds manufactured by an engineering approach to fabricate a potential tissue engineering product that provides both new tissue formation and wound healing. Thus, Hypericum perforatum oil (HPO) and vitamin A palmitate (VAP) incorporated gelatin (Gt) nanofibrous scaffolds were successfully prepared by the electrospinning method. Tannic acid (TA) was used as the cross-linking agent. The amounts of VAP and HPO loaded in the base Gt solution [15% w/v in 4:6 v/v acetic acid/deionized water] were 5 and 50 wt % (based on the weight of Gt), respectively. The obtained scaffolds were studied regarding their microstructure, chemical structure, thermal stability, antibacterial activity, in vitro release study, and cellular proliferation assay. In the light of these studies, it was determined that VAP and HPO were incorporated successfully in Gt nanofibers cross-linked with TA. Release kinetic tests confirmed that the patterns of TA and VAP release were consistent with the Higuchi model, whereas HPO release was consistent with the first-order kinetic model. In addition, this membrane was biocompatible with L929 fibroblast cells and had antibacterial activity and thermal stability. This preliminary study suggests potential applicability of the proposed dressing to treat skin wounds in clinics.

“…The increase in ber diameter observed in response to elevated concentrations of cotton linters is attributed to the higher cellulose content and increasing viscosity. Elevated viscosity levels generally result in an augmentation of ber diameter (Angel et al 2022;Gulzar et al 2022). This is achieved by implementing higher polymer concentrations within the solution or utilizing polymers with larger molecular weights.…”

The production of nanofibers based on cellulose has attracted considerable interest due to their remarkable biocompatibility and thermal and mechanical characteristics, rendering them increasingly popular for numerous biomass-based fibrous applications. The current research describes the electrospinning process of cellulose utilizing cuprammonium solutions. Polyethylene oxide (PEO) is also introduced to improve electrospinning and end material characteristics. The impact of the cellulose source, cellulose concentration, PEO molecular weight, and PEO concentration on spinnability and fiber morphology was systematically investigated. The analysis of membrane morphology and other associated characteristics was conducted through scanning electron microscopy with X-ray diffractometer and X-ray photoelectron spectroscopy techniques. A direct relationship exists between cellulose concentration and PEO molecular weight, resulting in an observed enhancement in fiber diameter. The nanofiber membranes demonstrate notable antibacterial characteristics for Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) owing to copper nanoparticles due to cuprammonium solution. Hence, the nanofiber membranes exhibit promising potential for utilization in several domains, such as water treatment, food packaging, medical, and separation.

“…In addition, consumers are now eager to support food products that are aware of the sustainable living lifestyle [ 2 ]. Therefore, biocomposite packaging films have been widely applied on several food product types, using various biopolymers [ 3 ], rice [ 1 ], corn [ 4 ], soy protein isolate [ 5 ], gelatin [ 6 ], chitosan [ 7 ], polylactic acid [ 8 ], etc. However, the application of bio-based food packaging must ensure the safety and quality of food products [ 9 , 10 ].…”

Dragon Fruit Peel Extract Enriched-Biocomposite Wrapping Film: Characterization and Application on Coconut Milk Candy

Bio-based film is an eco-friendly alternative to petroleum-based packaging film. The effects of biocomposite wrapping film enhanced with dragon fruit peel extract (0, 2% w/v, respectively) and currently used commercial packaging film (polypropylene; PP) on coconut milk caramels during storage (30 °C, 75% RH, nine days) were studied. Both 0% and 2% DPE-enriched biocomposite films were thicker and had higher water vapor permeability and solubility than the PP film but poorer mechanical characteristics. In addition, the 2% film possessed antioxidants and antioxidant ability. A FESEM micrograph revealed the rough surface and porous path of the biocomposite films. Over the storage time, the moisture content, water activity, and springiness of the coconut milk caramel candy wrapped in the PP and all DPE-enriched biocomposite films were not significantly altered. However, the lipid oxidation as the thiobarbituric acid reactive substance (TBARS) and hardness of all coconut caramels were significantly (p < 0.05) increased during storage. Furthermore, the hardness of coconut candy covered in the control (0% DPE) biocomposite film was more pronounced on day nine of storage. However, the changes in quality characteristics of the coconut candy wrapped in each film type need to be better established. The investigating factors influencing the quality deterioration of coconut milk candy should be further identified to mitigate their effects and extend the shelf-life of the coconut candy.
