Abstract
New antimicrobial nancomposites based Zr(MoO4)2·3H2O was developed through the sonication impregnation with natural polymers (chitosan and alginate). These materials were physiochemical characterized using X-ray powder diffraction technique (XRD), SEM, FTIR spectra and DTA/TG thermal analysis. The XRD results confirmed the amorphous properties of Zr(MoO4)2 which hold semicrystalline nature after impregnation with the polysaccharides. The data have shown that these composites reveal high thermal and chemical stabilities and microstructure surface coated with nanoscale units. Doping of such nanoparticles ((Zr(MoO4)2, Zr(MoO4)2/chitosan and Zr(MoO4)2/alginate)) into fresh mango juice in 0.01% compared to sodium benzoate additive and control sample demonstrate a superior antimicrobial properties. The data revealed that the best treatment in retardation of the microbial load (total bacterial, psychrophilic bacteria, spore-forming bacteria, total molds, and yeasts counts) was detected in fresh mango juice samples prepared using 0.01% additives are in the following order; ZrMo/chitosan > ZrMo/alg > ZrMo ≫ sodium benzoate additive. It was observed no any undesirable changes in biological characters (body weight, relative organs weigh, serum cholesterol, triglycerides, HDL, LDL, urea, creatinine, GPT and GOT) of albino rats received a fresh meal of mango juice doped with these nanoparticles. This result confirmed the safe application and positive impact of the modified nanoparticles in fresh mango juice to extend shelf life keeping the quality of their sensory properties.
