Published: May 1, 2025

ABSTRACT This study investigates the properties of a biocomposite film made from gelatin and sustainably sourced keratin incorporating chitosan‐functionalized silver nanoparticles. Varied concentrations chitosan solution (i.e., 0.4%, 0.6%, 0.8%, 1% w/v) were used in synthesis nanoparticles, their particle size, distribution, antibacterial antifungal activities evaluated against foodborne pathogens ( Escherichia coli , Staphylococcus aureus Rhizopus stolonifer Aspergillus niger ). The addition enhanced film's tensile strength to 16.64 MPa, 403% increase compared film. However, 2% functionalized nanoparticles reduced 9.07 MPa Gelatin‐Keratin distribution interaction between polymer chains analyzed using scanning electron microscopy Fourier transform infrared spectroscopy. composite films also exhibited significant UV blocking efficiency, achieving 99% blockage ultraviolet A 100% B. biocompatibility was tested with MG63 cell lines, showing that nanoparticle (0.3%–2%) improved viability 87% after 96 h incubation. These findings reveal bionanocomposite exhibit strong properties, along excellent biocompatibility, making them ideal materials for wound healing tissue engineering applications.

Published: July 2, 2024

ABSTRACT In this study, dragon fruit peels were subjected to different times (5, 10, 15, 20 and 25 min) of ultrasound pretreatment (4.870 W m −2 /25°C) then freeze‐drying (FD) (−56°C/48 h) obtain powder particles, which underwent physical–chemical, functional structural characterisation. Additionally, the extraction total phenolic compound (TPC) was evaluated through ultrasound‐assisted kinetics mechanical agitation. Finally, films based on black rice starch developed with addition (0.5, 1.5 2.5%) peel their physical, barrier, antioxidant, properties evaluated. The results obtained showed that all particles had low water content (4.21%–6.58%) high solubility (84.62%–88.73%) a reduction in particle size (23.21–39.32 μm). TPC, synergistic effect tested conditions increased efficiency, reaching 686.66 mg GAE/100 g for pretreated (25 180 min extraction. Furthermore, type ‘A’ crystallinity structure did not change significantly pretreatment, but there peak area, reflecting relative crystallinity, maximum decrease 29.04%. starch‐based produced 2.5% (28.72%) vapour permeability (5.03 × 10 −8 mm s −1 2 Pa), however, they contained higher levels TPC (31.78 film) antioxidant activity (8.17 μmol TE/g easily migrated aqueous medium. also presented values tensile strength at break (3.41 MPa) Young's modulus (4.18 MPa), as well value elongation (45.82%). our highlight potential FD peels, paving way development food packaging.
