copper nanoparticles in food packaging

Food Packaging: A Review Cornelia Vasile ... biocides, active packaging, silver nanoparticles as antimicrobial agents, nutrition and nutraceuticals, ... copper and copper oxides, starch nanocrystals, cellulose nanofibres and nanowhiskers, chitosan and chitin whiskers and others. Among the various metal nanoparticles, silver (Ag), copper (Cu), and zinc (Zn) nanoparticles are preferentially used as antimicrobial agents. Metal nanoparticles have been synthesised by means of laser ablation, a rising and easy … The synthesis of metal nanoparticles using plant extracts is a very promising method in green synthesis. Food crop production can be increased by the development of drought- and insect-pest-resistant crop varieties and microorganisms. These nanoparticles have been applied to packaging system using different ways. A new type of nanomaterial has been developed as antibacterial additive for food packaging applications. This chapter aims to give an overview about the use of nanoparticles for food packaging and introduce the nanoclay and metallic nanoparticle types. Silver nanoparticles in food packages U.S. Food and Drug Administration as generally recognized as safe (GRAS) materials (Emamifar et al., 2012), there is a concern about the potential health effects associated with high intake levels caused by migration of these particles from the packaging The important fields in which nanotechnology has demonstrated prominent applications include smart food packaging, food manufacturing, processing, and food preservations , , . The medicinal value of Moringa oleifera leaves and the antimicrobial activity of metallic copper were combined in the present study to synthesize copper nanoparticles having a desirable added-value inorganic material. This nanocomposite is composed of copper nanoparticles embedded in polylactic acid, combining the antibacterial properties of copper nanoparticles with the biodegradability of the polymer matrix. Recent developments on active packaging produced by the use of nanoparticles are summarized. Various metal nanoparticles may be applied for the development of novel nanoantimicrobials, which can be used as an effective tool for the management of plant diseases. Crop losses mainly occur due to biotic factors, which include soil-borne phytopathogens, i
