The investigation of novel nanoparticles with antimicrobial activity has grown in recent years due to the increased incidence nosocomial infections occurring during hospitalization and food poisoning derived from foodborne pathogens. Antimicrobial agents are necessary various fields which biological contamination occurs. For example, packaging they used control by microbes, medical field microbial important for reducing risk invasive routine interventions, textile industry, can limit growth microorganisms sweat. combination nanotechnology materials that have an intrinsic result development substances. Specifically, metal-based attracted much interest their broad effectiveness against pathogenic high surface area reactivity. aim this review was explore state-of-the-art nanoparticles, focusing on synthesis methods, types, action. Different techniques synthesize were discussed, including chemical physical methods “green synthesis” free agents. Although most studied properties metallic or metal-oxide other types such as superparamagnetic iron-oxide silica-releasing systems also exhibit properties. Finally, since quantification understanding action key topics, several evaluating vitro common mechanisms (e.g., cell damage changes expression metabolic genes) discussed review.

Applications of Inorganic Nanoparticles in Food Packaging: A Comprehensive Review

Polymers, Journal Year: 2022, Volume and Issue: 14(3), P. 521 - 521

Published: Jan. 27, 2022

Nanoparticles (NPs) have acquired significance in technological breakthroughs due to their unique properties, such as size, shape, chemical composition, physiochemical stability, crystal structure, and larger surface area. There is a huge demand for packaging materials that can keep food fresher extended periods of time. The incorporation nanoscale fillers the polymer matrix would assists alleviation material challenges while also improving functional qualities. Increased barrier thermal properties like melting point glass transition temperatures, changed functionalities wettability hydrophobicity are all features these polymers containing nanocomposites. Inorganic nanoparticles potential reduce growth bacteria within packaging.
