“…Figure 8 confirms the presence of À OH groups, and À NH2 groups giving room for chemical modifications resulting in different, new, and improved materials. [39] The degree of treatment influences the physical and chemical properties of chitosan extending the range of applications. The film-forming abilities of chitosan are recognized due to the hydrogen-bonds network formation, making its hydrophilic character and antimicrobial properties especially desired for the production of new biomaterials.…”

Membrane separation has been an upgrade in our quest for eco-friendly processes because of its minimal energy usage and lesser waste generation. However, the most widely used membranes are polymeric membranes. Most of these membranes are non-biodegradable and are replaced after deterioration/fouling and then discarded. Dumping without treatment on a large scale is a significant environmental problem. Green polymers only make up a limited percentage of all the new materials that are reported every year. We require more research in developing renewable, inexpensive membranes from waste materials to ensure progress with the least toll on the environment. Several reported green methods can partially achieve green synthesis. This ensures the least use of nonbiodegradable polymers in membranes. This review will emphasize the exploration of more natural materials given the target is to fabricate membranes in a way, where both raw material and membrane preparation are green.

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.
