Abstract

Nowadays, traditional packaging films with weak activity or single function cannot satisfy the active packaging requirements. In this paper, novel multifunctional films (TNC/GSE/AgNPs) based on TEMPO-oxidized nano-cellulose (TNC), grape seed extract (GSE) and TNC immobilized silver nanoparticles (TNC@AgNPs) are reported. The results showed that transparent TNC/GSE/AgNPs films exhibited better mechanical properties, lower water vapor permeability and oxygen permeability compared to pure TNC films. Moreover, due to the effect of TNC immobilization on AgNPs, only 5.77%, 3.62% and 3.11% of AgNPs were released from TNC/GSE/AgNPs films under the pH 4.0, 6.9 and 9.2, respectively. Nevertheless, the films had good antimicrobial activity against E. coli and S. aureus. Moreover, TNC/GSE/AgNPs films showed strong antioxidant activity which has been evaluated by DPPH (6.87 μg Vc/mg d.w.) and TRAP (82.67 μg Trolox/mg d.w.) methods. The prepared films will exhibit multifunction as food packaging to extend storage period.
