A novel formulation of active hexagonal‐compact nano packed composite system using emerging technology for food packaging applications

Abstract

We report the nanoformulation of the active hexagonal‐compact nano‐packed composite system with iron oxide nanoparticles and glossy glutinous chitosan‐tapioca starch biopolymer solution (CTS‐S) for improved potential benefit in food packaging applications. The high pressure processing (HPP) treatment at various pressure level ranging from 100 to 500 MPa at constant time 120 s and optimized the formation of hexagonal nano‐packed system at 500 MPa. The UV–vis spectrophotometer (UV), Fourier transform infrared spectroscopy (FTIR), x‐ray diffraction (XRD) and Zeta potential analysis suggested uniform dispersion of iron oxide nanoparticles and formulated an effective stable nano‐packed composite structure. The XRD analysis of HPP treated sample confirmed the enhancement in material properties with high degree of crystallinity nature. Further studies on antimicrobial effects for HPP treated nano‐packed composite solution exhibited an excellent antimicrobial property and examined over a period of 1 month against microbial deterioration. The study revealed that the novel nano‐packed composite solution could be used as an antimicrobial food packaging material. Practical application The research focused to the development of novel formulation of active hexagonal nano‐packed composite system using non‐thermal high pressure pascalization (HPP) technology. For the first time the design of compact nano structural pattern from the composite solution was developed which expresses an anti‐microbial characteristic even after exposed to environmental condition for a month. The experimental results revealed the practical application of formulated nano‐packed composite system with improvement bio‐physical properties and material characteristics has created an interest toward the food‐borne microbial barrier coating material which can be used in food packaging applications as well as promoting longer shelf life of food products with fabrication of nano‐packaging material as a commercial beneficial aspect in food packaging industries.
