ZnO nanoparticles (ZnO‐NPs) are nanoscale representatives of ZnO, which is an approved food additive. ZnO‐NPs are used as fillers for food packaging, however, the migration of ZnO‐NPs from film to food is a real concern. The current study was oriented toward the migration of ZnO‐NPs from packaging material into food. ZnO‐NPs were synthesized in the lab with or without capping material and characterized using SEM and TEM, FTIR, and XRD to study morphology, functional group, and size of the nanoparticle, respectively. Rod‐shaped and flake‐shaped ZnO‐NPs were formed depending upon precursor. Bio‐nanocomposite films were prepared by incorporating these ZnO‐NPs into the gelatin matrix. The migration study was conducted using AAS considering variations in time, temperature, and composition. It was found that migration level increased with increasing concentration of ZnO‐NPs, temperature, and time. Concentration had the highest significance as compared to the other two parameters. Toxicity was also evaluated and it was found to be safe for human consumption. Novelty impact statement Quantification of migrated nanoparticles was done, with the variation in time, and temperature of storage along with the concentration of nanoparticles. A migration study was conducted from bio‐nanocomposite packaging film to the food instead of food simulants/buffer solutions. Toxicity evaluation of migrated nanoparticles was investigated.

Photocatalysis is the most environmentally benign and efficient method for degrading organic dyes in water purification. Herein, the synthesis of ZnO nanoparticles was achieved by simple homogeneous chemical precipitation via the support of adipic acid and followed the calcination process at elevated temperatures. Based on the physical and morphological characterization analysis, the high crystallinity hexagonal structure with uniform granular shape morphology of the ZnO nanoparticles was formed with a band gap of 3.2 eV. The photocatalytic performance of the ZnO nanoparticles was investigated with the degradation of methylene blue (M.B.) dye as a model compound in an aqueous medium under UV light irradiation. The optimal ZnO‐700 nanoparticles demonstrated the highest photocatalytic activity thanks to their large surface area and numerous oxygen vacancies. More importantly, a small amount of photocatalyst (0.4 g/L) successfully degraded M.B. dye from an aqueous solution with 100 % efficiency within just 11 minutes of irradiation time under UV light with protective photocatalytic activity 4 sequential cycles. Besides, in‐depth photocatalysis experiments present that via a facile two‐step synthesis method, the as‐prepared ZnO photocatalysts depict enhanced chemical stability in a harsh environment and efficient photodegradation.

“…Dyes are considered seriously hazardous for the environment because dyes are highly soluble in water [1,2]. Commonly, methyl orange, methylene blue, rhodamine B, Congo red, and orange G are used in several industries including pharmaceutical, textile, and food [3,4]. Numerous oxidants agents are used for degrading organic contaminants [5].…”

In recent years, nanoparticles synthesis by green synthesis has gained extensive attention as a facile, inexpensive, and environmentally friendly method compared with chemical and physical synthesis methods. This review covered the biosynthesis of zinc oxide nanoparticles (ZnO NPs), including the procedure and mechanism. Factors affecting the formation of ZnO NPs are discussed. The presence of active bioorganic molecules in plant extract played a vital role in the formation of ZnO NPs as a natural green medium in the metallic ion reduction processes. ZnO NPs exhibit attractive photocatalysis properties due to electrochemical stability, high electron mobility, and large surface area. In this review, the procedure and mechanism of the ZnO photocatalysis process are studied. The effects of dyes amount, catalysts, and light on photodegradation efficiency are also considered. This review provides useful information for researchers who are dealing with green synthesis of ZnO NPs. Moreover, it can provide investigators with different perceptions towards the efficiency of biosynthesized ZnO NPs on dyes degradation and its restrictions.
