multifunctional betanin nanoliposomes incorporated gelatin chitosan nanofiber zno nanoparticles Nanocomposite Film for fresh beef preservation
Meat Science, 2020Co-Authors: Sajed Amjadi, Maryam Nazari, Safar Ali Alizadeh, Hamed HamishehkarAbstract:Abstract The objective of this study was to fabricate betanin nanoliposomes incorporated gelatin/chitosan nanofiber/ZnO nanoparticles bioNanocomposite Film (G/CH NF/ZnO NPs/B NLPs) and investigate its effects on the preservation of fresh beef. The scanning electron microscopy image of Nanocomposite Film displayed a good inter-connective porous morphology. Fourier transform infrared and X-ray diffraction analysis confirmed the formation of new hydrogen bonds and enhanced crystallinity through the addition of CH NF, ZnO NPs, and B NLPs. The G/CH NF/ZnO NPs/B NLPs Film exhibited satisfactory mechanical properties and high surface hydrophobicity (water contact angle = 92.49 ± 3.71°). The incorporation of ZnO NPs and B NLPs in the Nanocomposite Film provided high antibacterial activity and DPPH inhibition activity (53.02 ± 3.26%). The growth of inoculated bacteria, lipid oxidation, and the changes in the pH and color quality of the beef samples were controlled by packaging with the fabricated Film. In conclusion, the G/CH NF/ZnO NPs/B NLPs Nanocomposite has a high potential for meat preservation.

application of reinforced zno nanoparticle incorporated gelatin bioNanocomposite Film with chitosan nanofiber for packaging of chicken fillet and cheese as food models
Food and Bioprocess Technology, 2019Co-Authors: Sajed Amjadi, Maryam Nazari, Sana Emaminia, Shabnam Heyat Davudian, Leila Roufegarinejad, Hamed HamishehkarAbstract:The food packaging industry has shown increasing attention toward biodegradable active packaging because of consumer demand for the extended shelf life of food products, as well as environmental concerns. In this study, the gelatin-based Nanocomposite containing chitosan nanofiber (CHINF) and ZnO nanoparticles (ZnONPs) were fabricated and characterized by SEM analysis. The fabricated Nanocomposite Film revealed high antibacterial activity against foodborne pathogenic bacteria. To assess the efficiency of this bioNanocomposite Film for food packaging, chicken fillet and cheese was selected as food models. The results showed that the wrapping with Nanocomposite Film significantly (p < 0.05) decreased the growth of inoculation bacteria in chicken fillet and cheese samples. The changes in pH values and color parameters in chicken fillet and cheese samples were controlled by wrapping with Nanocomposite Film during storage time. At the end of 12-day storage, the weight loss of the wrapped chicken fillet and cheese samples with Nanocomposite were 18.91 ± 1.96 and 36.11 ± 3.74%, respectively. In addition, the organoleptic characteristics of wrapped chicken fillet and cheese samples with Nanocomposite Film were acceptable until the end of storage. In conclusion, the fabricated Nanocomposite can be suggested as a suitable packaging material for poultry meat and cheese to improve their shelf life and quality.

physicochemical and antifungal properties of bio Nanocomposite Film based on gelatin chitin nanoparticles
International Journal of Biological Macromolecules, 2017Co-Authors: Samar Sahraee, Jafar Mohammadzadeh Milani, Babak Ghanbarzadeh, Hamed HamishehkarAbstract:The gelatin-based Nanocomposite Films containing chitin nanoparticles (N-chitin) with concentrations of 0, 3, 5 and 10% were prepared and their physical, thermal and anti-microbial properties were investigated. Scanning electron microscopy (SEM) micrographs showed that N-chitin size distribution was around 60-70nm which dispersed appropriately at low concentration in gelatin matrix. The results showed that incorporation of N-chitin significantly influenced apparent color and transparency of the gelatin Films. The reduced water vapor permeability (WVP) and solubility and higher surface hydrophobicity of the Nanocomposite Films were obtained by enhancing N-chitin concentration in Film formulation. The use of N-chitin up to 5% concentration in the gelatin based Nanocomposite Film led to improved mechanical properties. Also, the results of differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) confirmed improved stability of Nanocomposite Films against melting and degradation at high temperatures in comparison to neat gelatin Film. The well compatibility of chitin nanoparticles with gelatin polymer was concluded from Fourier transform infrared (FTIR) spectra and X-ray diffraction (XRD) plots. Finally, the gelatin based Nanocomposite Films had anti-fungal properties against Aspergillus niger in the contact surface zone. Increasing the concentration of N-chitin up to 5% enlarged inhibition zone diameter, but the Nanocomposite Film containing 10% N-chitin showed smaller inhibition zone.

differential pulse voltammetric determination of methyl parathion based on multiwalled carbon nanotubes poly acrylamide Nanocomposite Film modified electrode
Journal of Hazardous Materials, 2012Co-Authors: Yanbo Zeng, Yanyan Yu, Dajun Yu, Tianshu ZhouAbstract:Abstract A sensitive electrochemical differential pulse voltammetry method was developed for detecting methyl parathion based on multiwalled carbon nanotubes–poly(acrylamide) (MWCNTs–PAAM) Nanocomposite Film modified glassy carbon electrode. The novel MWCNTs–PAAM Nanocomposite, containing high content of amide groups, was synthesized by PAAM polymerizing at the vinyl group functionalized MWCNTs surface using free radical polymerization. The MWCNTs–PAAM Nanocomposite was characterized by Fourier transform infrared spectroscopy, thermal gravimetric analysis and scanning electron microscopy. Electrochemical behavior and interference studies of MWCNTs–PAAM/GCE for methyl parathion were investigated. The experimental results demonstrated that the MWCNTs–PAAM/GCE exhibited a high adsorption and strong affinity toward methyl parathion compared with some metal ions and nitroaromatic compounds, which exist in environmental samples. The adsorbed amount of methyl parathion on the MWCNTs–PAAM/GCE approached the equilibrium value upon 5 min adsorption time. A linear calibration curve for methyl parathion was obtained in the concentration range from 5.0 × 10−9 to 1.0 × 10−5 mol L−1, with a detection limit of 2.0 × 10−9 mol L−1. The MWCNTs–PAAM/GCE was proved to be a suitable sensing tool for the fast, sensitive and selective determination of methyl parathion in environmental water samples.
