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 photocatalytic properties of ZnO may vary with particle size, morphology, and crystallinity of the materials. Modifications such as thermal treatment and/or doping the materials with other metals ions could enhance photocatalytic activity through limiting the recombination of electron-hole pairs and improving the absorption of light [41][42][43][44][45][46][47]. Under the current scenario of water pollution [48][49][50][51][52][53][54][55], there is need to prepare and utilized catalysts active under solar light to enhanced the cost effectiveness of catalytic process [56].…”

In view of enhanced bioactivity and photocatalytic applications, the doped material has gained much attention and present study was focused on the preparation of Zn doped WO 3 (Zn-d-WO 3 ) via precipitation method. The prepared Zn-d-WO 3 was characterized by Scanning Electron Microscopy (SEM), x-ray diffraction (XRD), Energy-dispersive x-ray (EDX). The effect of Zn concentration was studied on antibacterial, antifungal and photocatalytic activities along with structural and morphological variation. The Zn-d-WO 3 was triclinic, spherical and rod shaped and particle size was decreased as the Zn concentration increased. The antimicrobial activity of Zn-d-WO 3 was evaluated against a panel of bacterial strains (Escherichia coli, Pasturellamu ltocida, Bacillus subtilis, Staphylococcus aureus) and fungal strain (Aspergillus niger, Aspergillus flavus, Penicillium notatum). The Zn-d-WO 3 showed promising antibacterial activity with minimum inhibitory concentration (MIC) values in the range of 211-387 (μg ml −1 ), whereas the antifungal activity was less than the standard (Fluconazole), which revealed that the Zn-d-WO 3 are highly active against bacterial strains since activity was comparable with standard drug (Rifampicin). The photocatalytic activity (PCA) was evaluated by degrading methylene blue (MB) dye in an aqueous solution and dye degradation of 78% and 92% was achieved in 120 min under visible and UV irradiation, respectively. Results revealed that the Zn-d-WO 3 could possibly be used as photocatalyst for the degradation of dyes in wastewater.

In recent years, the nanotechnology has gained much attention since the nanoparticles (NPs) have applications in every field of life. The hetero-structured are of special interest due to their higher photocatalytic activity. In present investigation, Zinc vanadate NPs were synthesized from vanadium and zinc salts by microwave assisted precipitation method. The Zinc vanadate NPs were characterized by x-ray Powder Diffraction (XRD), Energy-dispersive x-ray spectroscopy (EDX), Scanning electron microscope (SEM) and UV-visible techniques. The photocatalytic activity (PCA) was evaluated by degrading the methylene blue (MB) dye and process variables were optimized. The Zinc vanadate size was <100 nm and particles were in aggregates form. The MB dye degradation was performed at different conditions of process variables and it was observed that MB dye was significantly degraded using Zinc vanadate NPs under UV light irradiation. The reaction time, catalyst dose and dye initial concentration showed variable effect on dye degradation. Based on results, it can be concluded that the microwave irradiation is viable for the synthesis of Zinc vanadate NPs for photocatalytic activity. In view of promising efficiency of Zinc vanadate NPs, it can be used for the dye degradation and for the remediation of textile effluents.
