Oxidation causes spoilage and the inedibility of the fruit. However, traditional packaging films without antimicrobial or antioxidant activities do not satisfy the active packaging requirements. Films with antimicrobial and antioxidant activities are urgently required. In this study, silver nanoparticles (AgNPs) were synthesized from fruit waste grape seed extracts (GSE). The antimicrobial and antioxidant activities of GSE-silver nanoparticles (GSE-AgNPs) and AgNPs (average size 20 nm) stabilized by polyvinyl pyrrolidone (PVP-AgNPs) were evaluated in vitro. The effect of chitosan (CS)-coated GSE-AgNPs and PVP-AgNPs on the postharvest quality of grape was studied during storage at 20 °C for 5 days. The results confirmed that grapes treated with CS and GSE-AgNPs showed significantly reduced decay percentage, weight loss, and maintained titratable acidity at high levels compared with those of untreated fruit and fruit treated with PVP-AgNPs. Moreover, CS and GSE-AgNPs significantly inhibited the total mold count during storage. Our results suggest that CS coating enriched with GSE-AgNPs has the potential to preserve the quality and extend the shelf life of grapes.
