Functionalization of sugarcane bagasse–based paper with amla pomace/titanium dioxide nanoparticles providing antimicrobial protection for food safety

The non-wood pulp fibers in the paper and printing industry have been in demand for economic and environmental necessity. In this communication, the agro-processing waste sugarcane bagasse (SCB) and amla pomace was used to develop a packaging application paper. The physical and mechanical properties of non-wood pulp remain an issue for further application. The synergistic effect of nanoparticle TiO2and amla pomace addition into the SCB was investigated. The developed SCB paper evaluated the physical, mechanical, and barriers to moisture. The molecular interaction between the constituents of paper was investigated with FTIR. The paper’s morphological crystallinity and surface topology behavior were observed in FESEM, XRD, and AFM analysis. The analysis results indicate that the SCB utilization approach could bring a sustainable solution for non-wood pulp. The mechanical properties of the paper have not been considerably affected by the addition of TiO2. The water vapor barrier quality improved as compared to the control bagasse paper. The microstructural topology of the paper is well elaborated through FESEM and AFM. The crystallinity of the paper has been significantly affected by the addition of TiO2. The EDX analysis confirms the elemental composition of cellulose and TiO2particles in the paper sheets. In conclusion, the results may not have significantly affected the paper’s performance. The antibacterial effectiveness of paper was determined by analyzing its ability to inhibit the growth of E. coli. It was discovered that the antibacterial activity of paper increased as TiO2concentration increased. Still, the approach to developing paper from agro-processing waste sources with nanoparticles can take a step toward a sustainable packaging solution.
