Synthesis Of Ecofriendly Nanogranular Films In Food Packaging Using Medicinal Plants And Nanoparticles

Abstract

Food borne diarrhea is becoming a major public health problem with higher morbidity and newlinemortality rate among the people and food safety is becoming a worldwide issue due to the presence of newlinepathogenic bacteria in foods. The findings of the study are among the four medicinal plans, it was newlineobserved that Glycyrrhiza glabra AgNP showed a smaller particle size of 34.7 nm with highest newlinesuspension stability of -28.9 mV, compared to other AgNP of plant extracts. The highest antioxidant newlinecontent of Glycyrrhiza glabra could be due to presence of phyto constituents in the plant extract. The newlineFTIR confirmed the presence of phenols, which showed a narrow and sharper peak at 578.06 cm-1, newlinewhich could be one of the reason for its maximum antioxidant potential. Greater interaction of water newlinewith silver could be the reason for OH stretching at 3410.10 cm-1 involved in capping of AgNP. It newlinewas observed that the DNA fragmentation increased on exposure to Glycyrrhiza glabra AgNP. newlineHence, 30 and#956;l of Glycyrrhiza glabra nanoparticles was selected as the best colloidal solution for newlinecoating onto the food packaging material such as PET, infant feeding bottles (Poly Propylene) and newlineZip lock covers (Poly Ethylene). In the present study, an increase in crystallinity of these Ag newlinenanoparticle impregnated film of 0.01 and 0.05 per cent may be due to the OH groups of amylose in newlinetapioca starch, which improved the interaction with nanoparticles and glycerol. Therefore, both the newlinenanocoating and edible film are more potent against the diarrheal species which could be due to newlinesynergisitc action of both the antioxidant and antimicrobial property of Glycyrrhiza glabra silver newlinenanoparticles. It also increases the shelf life of foods against diarrheal pathogens ensure total food newlinesafety and are ecofriendly in nature. newlinei) Major objectives : newline1. Develop food containers with longer inhibition for diarrhea causing bacteria employing newlineplants extracted with silver nanoparticles newline2. Design food packaging containers for sustained sterility over longer duration using silver
