It has been traditionally used for the treatment of diseases such as pharyngeal disorder, common cold, colic ulcer, and diarrhea. The aim of the present study was to evaluate the physico-mechanical and antimicrobial properties of quince seed mucilage supplemented with titanium dioxide (TiO2) and silicon oxide (SiO2) nanoparticles. Methods: The antimicrobial property of designated QSM against Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Listeria monocytogenes, Salmonella typhimurium, and Escherichia coli O157:H7 was determined using agar disk diffusion and broth micro-dilution assays. Thickness, tensile strength (TS), puncture force (PF), puncture deformation (PD), swelling index (SI), and color of active QSMs were evaluated using analytical instruments. Results: The films containing TiO2 and SiO2 nanoparticles exhibited good antimicrobial effects against S. aureus, B. subtilis, B. cereus, L. monocytogenes, S. typhimurium, and E. coli O157:H7 ranged 0.82-6.88 mm and -2.78 - -0.28 log differences in population (DP) regarding agar disk diffusion and broth micro-dilution assays, respectively. The presented values, including TS, PF, and PD of QSM films, were in the ranges of 22.45-35.81 MPa, 10.42-15.49 N, and 15.53-18.45 mm, respectively. Conclusions: Application of TiO2 and SiO2 nanoparticles greatly improved the antimicrobial and physico-mechanical properties of the prepared films.
