“…Further, the storage test indicated that the smoked salmon packed with the GVE film containing 3% ZnO NPs showed the strong antibacterial activity against pathogenic bacteria and lower degree of lipid oxidation compared with control, indicating that this nanocomposite could be applied as an active food packaging material for smoked salmon. [95] Kumar et al (2019) prepared agar-ZnO nanocomposite films using solution casting method and applied as an active packaging material for extending shelf life of green grape. In this study, the ZnO NPs were synthesized using Mimusopselengi fruit extract in polyhedral shapes (mostly hexagonal) with the size of 14-48 nm (average size of 24.75 ± 0.78 nm).…”

Packaging of food products is one of the most important stages of the food supply chain. Nano-size materials for packing food substances with appropriate properties result in better packaging performance and longer food shelf-life. In this review, the application of ZnO nano-size in active packaging of foods is discussed to identify gaps in applications for food packaging and safety. First, the crystal structures and morphologies of modified ZnO nanoparticles (ZnO NPs) are presented, and their synergistic effects on antimicrobial activities are discussed. This review also provides an overview of antimicrobial packaging containing ZnO NPs with a focus on preparation methods, antimicrobial mechanisms, and recent progress in packaging applications. The generation of reactive oxygen species (ROS) is the primary antimicrobial mechanism, which can be varied depending on morphology and size. Generally, ZnO NPs can inactivate fungi or Gram-positive and Gram-negative bacteria growth, which reduce the risk of cross-contamination, thereby extending the shelf life of products. Notably, the health concerns and hazards regarding the safety and migration of ZnO NPs application are also elaborated. Unintentional migration, inhalation, skin penetration, and ingestion may result in human health hazards. Therefore, to provide safety regulations, further investigations such as case by case study are recommended.

“…The L*, a*, and b* values were examined on the standard plate (L*: 96.79, a*: -0.15, and b*: 2.00) according to the CIELAB color scale. The opacity and light transmittance (200-800 nm) of the KWS films with MLE were obtained based on the method reported by Baek and Song (2018b) using a spectrophotometer (UV-2450, Shimadzu Co., Kyoto, Japan).…”

The aim of this study was to develop and characterize the properties of khorasan wheat starch (KWS) films containing moringa leaf extract (MLE) as an antioxidative packaging material. KWS was isolated from khorasan wheat and used as a film base material. Different amounts (0, 0.4, 0.7, and 1.0%, w/v) of MLE were added to the KWS film-forming solution and the film properties were examined. Tensile strength of the KWS films decreased and elongation at break increased with increasing MLE content. In addition, the KWS films containing MLE possessed good antioxidative activities and ultraviolet light blocking ability. In particular, 2,2 0-azino-bis (3ethylbenzothiazoline-6-sulfonic acid) and 2,2-diphenyl-1picrylhydrazyl radical scavenging abilities of the KWS films with 1.0% MLE were 59.45% and 37.89%, respectively. Moreover, KWS films containing 1.0% MLE were biodegradable within 30 days. These findings indicate that the developed KWS films containing MLE can be applied as a biodegradable packaging material with antioxidative activity.

“…Because of environmental toxicity and pollution, many researchers have suggested the green synthesis route for the synthesis of ZnO NPs from cheap natural biowastes or agricultural wastes, such as leaf, flower, and seed. [2,15,16] Many studies have indicated that plant extracts could act as a reducing, capping, and stabilizing agent during the production of metallic NPs at ambient conditions due to their simplicity and costeffectiveness. [17] The agrowastes contain secondary metabolites and reduce metal ions by bioactive compounds present in them, such as enzymes, phenolic and flavonoid compounds, vitamins, and amino acids.…”

To increase the profitability and sustainability of agricultural waste, a facile green approach was established to synthesize zinc oxide nanoparticles (ZnO NPs) using saffron leaf extract as a reducing and stabilizing agent. Structural characteristics of NPs were investigated by X-ray diffraction (XRD), Fouriertransform infrared (FTIR), field emission scanning electron microscopy (FESEM), and UV-Visible (UV-Vis) spectroscopy. Characterization results revealed that ZnO NPs is highly crystalline with a hexagonal wurtzite structure and spherical particles with diameter less than 50 nm, as confirmed by XRD and FESEM techniques. UV-Vis absorption spectra depicted an absorption peak at 370 nm, which confirms the formation of ZnO NPs. FTIR spectral analysis confirmed the presence of functional groups and metal oxygen groups. The biological activities of ZnO NPs were also investigated. The antibacterial effect of ZnO NPs was investigated against selected food pathogens (Salmonella Typhimurium, Listeria monocytogenes, and Enterococcus faecalis). The study results prove that the green synthesized ZnO NPs show enhanced antibacterial activity against S. Typhimurium when compared with other strains. A dose-dependent free radical scavenging activity was observed for ZnO NPs in both 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and fluorescence recovery after photobleaching (FRAP) assays. The ZnO NPs were evaluated for their photocatalytic activity during the degradation of methylene blue (MB) dye in aqueous solutions. The maximum removal of MB achieved was 64% with an initial ZnO NP concentration of 12 mg/mL under UV light. The present study revealed that the agricultural waste (saffron leaf) provides a simple and eco-friendly option to sustainably synthesize ZnO NPs for use as a photocatalyst. In addition, this is the first report on saffron leaf-mediated synthesis of ZnO NPs.
