Abstract

Straw-derived biosilica nanoparticles (SiNPs) loaded with oak fruit extract (OE@SiNP) were incorporated into quince seed mucilage/alginate (QSM/Alg) films to create eco-friendly active packaging materials. The structural and functional properties of the prepared particles, along with the effects of different concentrations of OE@SiNP on the physicochemical and functional properties of the films, were evaluated. The nanocomposite films containing 5 wt% OE@SiNP exhibited 100.0 % ABTS and 40.9 ± 0.8 % DPPH scavenging activities, in addition to UV-blocking capabilities of 96.5 ± 0.4 % for UV-A and 99.7 ± 0.1 % for UV-B. The addition of OE@SiNP enhanced the flexibility and hydrophobicity of the films. Moreover, the proposed QSM/Alg/OE@SiNP exhibited potent antibacterial activity, eradicating S. aureus, with the bacteria eliminated within 12 hours. As a result, minced pork was packaged with the manufactured film and stored at 4 ℃ for 20 days, during which quality changes were investigated. The experimental results demonstrated the effective preservation performance of the QSM/Alg/OE@SiNP film for packaged meat. Therefore, the developed multifunctional nanocomposite film shows significant potential for active food packaging applications. © 2025 Elsevier Ltd
