“…Different types of mechanical mills such as planetary, vibratory, rod, tumbler, and so on are commonly used. Some of the materials such as Co, Cr, W, Ni–Ti, Al–Fe, and Ag–Fe are made nanocrystalline using a ball mill (Satyanarayana & Reddy, 2018). Some of these nanoparticles provide antimicrobial, antifungal, antiyeast, and antiviral activities that can be used for active food packaging (Carbone, Donia, Sabbatella, & Antiochia, 2016).…”

“…If copper is used as a metal wire, then copper nanoparticles will be formed. Nitride, metal, and oxide nanoparticles are reported to be produced by using PWD (Satyanarayana & Reddy, 2018). The copper nanoparticle (CuNPs) produced from this method can be used for increasing shelf life of tomato by increasing its firmness.…”

“…The nanoparticles are formed at the electrode–electrolyte interface, where the electricity is the driving or controlling force. No vacuum system, low costs, simple operation, high flexibility, less contamination (pure product), and environment‐friendly process (eco‐friendly) are the advantages of this method (Satyanarayana & Reddy, 2018). The electrochemical method can produce silver nanoparticles of size less than or equal to 20 nm with the help of 0.01 mM concentration of silver nitrate solution along with glassy carbon electrode as working electrode and silver metal as counter electrode (Nakamura et al., 2019).…”

“…Also their high specific surface area makes them more reactive compared to larger particles of the same materials [6]. Generally, the synthesis of nanomaterials can be classified into two categories: bottom up and top-down [7]. Chemical vapor synthesis, sol-gel technique, electrodeposition, sputtering, mechanical attrition, chemical precipitation, colloidal chemistry are certain of the synthesis techniques [8].…”

Plant extracts were produced from Camellia sinesis (Green Tea) and Punica granatum (pomegranate), and the total concentration of polyphenols was measured in terms of equivalent concentration of Gallic acid by using the Folin-Ciocalteu method. Zero Valent Iron nanoparticles (nZVIs) were synthesized in a semi-batch reactor by mixing a pre-specified volume of plant extract or Gallic Acid solution with an aqueous solution of iron sulfate heptahydrate (FeSO4·7H2O). To monitor the kinetics of nZVI synthesis, the transient responses of solution pH and redox potential (Eh) were recorded with two probes adequately connected with a data acquisition card. The nanoparticles were characterized by a variety of techniques: Dynamic Light Scattering (DLS), ζ-potential, Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy, Transmission Electron Microscopy (TEM). A kinetic parametric model, based on two parallel single electron transfer (SET) and hydrogen atom transfer (HAT) reactions, was suggested to quantify the dynamics of ferrous ions reduction to zero valence, and its parameters were estimated for each experimental system by matching the transient response of pH. The temporal changes of redox potential during nZVI synthesis were indicative of the reaction progress and agreed with the numerical predictions in semi-quantitative basis. The numerical model enabled us to track the temporal variation of the concentration of iron and polyphenol species, and calculate the yield of ZVI synthesis. The reactivity of nZVIs was assessed by measuring their capacity to reduce hexavalent chromium Cr (VI) in aqueous solutions prepared from potassium dichromate (K2Cr2O7).

and methods. Nanoparticles are thought to be the smallest objects that may operate as a single entity, displaying novel behaviors and characteristics. [2] Since nanoparticles have a larger surface area and mass transfer rates than big particles (of the same composition), they seem to have higher biological and chemical activity, penetrability, catalytic behavior, enzymatic reactivity, and quantum characteristics. [3] The dimensions, construction, and properties of nanomaterials are used to classify them into several categories. Nanomaterials with a high surface-area-to-volume ratio (SA:V) have the potential to exhibit desirable physiochemical characteristics, including those related to diffusivity, solubility, color, thermodynamics, optics, and magnetization. [4] Nowadays, the food market is growing day by day. In 2023, the food market will generate $9.43 trillion in revenue. The market is expected to grow by 6.21% yearly. With a market volume of US$1.64 trillion in 2023, Confectionery & Snacks will be the market's largest sector. According to population estimates, US$1228.00 in income is expected per person in 2023. By 2023, internet sales in the food industry will account for 8.5% of total revenue. In 2023, it is estimated that the Food market would have a volume per person of 340.87 kg. Today, the market of food needs innovations that can make food that is easy to use, real, and delicious so that it can keep Over the course of the last several decades, nanotechnology has garnered a growing amount of attention as a potentially valuable technology that has significantly impacted the food industry. Nanotechnology helps in enhancing the properties of materials and structures that are used in various fields such as agriculture, food, pharmacy, and so on. Applications of nanotechnology in the food market have included the encapsulation and distribution of materials to specific locations, the improvement of flavor, the introduction of antibacterial nanoparticles into food, the betterment of prolonged storage, the detection of pollutants, enhanced storage facilities, locating, identifying, as well as consumer awareness. Labeling food goods with nano barcodes helps ensure their security and may also be used to track their distribution.
