Research Projects

The increasing global demand for safe, high-quality livestock products, along with the environmental impact of non-biodegradable packaging, highlights the need for sustainable, multifunctional food packaging solutions. This project aims to develop active and intelligent biodegradable films for real-time quality monitoring and preservation of livestock products, including meat, milk, and eggs, thereby addressing food waste and plastic pollution. The rationale comes from the limitations of traditional packaging, which often lacks real-time spoilage detection and uses environmentally harmful materials. By integrating nanomaterials, such as carbon dots (CDs), as active agents endowed with antimicrobial, antioxidant, and UV-blocking properties, coupled with natural colorimetric indicators for pH-responsive spoilage detection, the project presents an innovative and environmentally friendly packaging solution. The scientific objectives include synthesizing CDs from agro-industrial waste, extracting and stabilizing natural pigments, producing biodegradable films using biopolymer matrices, and testing their effectiveness in extending shelf life and monitoring quality. The hypothesis to be tested is that these films can both inhibit microbial growth and oxidation while detecting spoilage markers (e.g., total volatile basic nitrogen, pH shifts) through visible color changes, providing better performance than existing single-function packaging. Moreover, films embedded with active nano-materials will improve the quality of packaging indicators, making them more efficient. Key experiments include the hydrothermal synthesis of CDs, green extraction of pigments, solution casting for film production, characterization of mechanical, barrier, antimicrobial, and pH-sensitive properties, and testing the application on livestock products under various storage conditions. The effectiveness of the films will be evaluated based on microbial load, lipid oxidation, and the colorimetric response of indicators. The project’s significance lies in its potential to revolutionize food packaging by bridging the gap between active preservation and intelligent monitoring, where research has primarily focused on single-function systems. By utilizing agro-waste and plant-based materials, the project aligns with circular economy principles, thereby reducing environmental impact and production costs. Successful implementation could significantly advance the understanding of nanomaterial-pigment interactions in biodegradable matrices, providing insights into scalable and sustainable packaging designs. Practically, the films could reduce food waste by extending shelf life and enabling consumers and producers to monitor freshness, enhancing food safety in India’s livestock sector and we are confident that this work could set a precedent for multifunctional, biodegradable packaging systems, fostering further research and adoption in diverse food sectors.
