Abstract

Abstract An environmentally friendly antimicrobial film was developed by incorporating silver nanoparticles (AgNPs) into bacterial nanocellulose (BNC) via reduction (R) and UV-assisted (UV) methods. By mixing with 3 wt% polyvinyl alcohol (PVA) solution, the elongation at break of the films was improved 20 times that of pure BNC film. The films exhibited higher oxygen barrier capacity with slightly improved water vapor permeability. Antimicrobial activities against Escherichia coli O157:H7 were observed from both R and UV films with up to 7 and 3 log CFU/mL of reductions in liquid medium and on raw beef, respectively. A raw beef shelf-life study suggested that the films were able to inhibit the growth of naturally present bacteria for at least 10 days at 4 °C. The findings of this research indicate the potential of the AgNP/PVA/BNC films for applications in food packaging.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
