Carbon Dots as Functional Agents in Food Packaging

The paradigm of food packaging is undergoing a profound transformation in response to the evolving needs of modern consumers who are increasingly prioritizing convenience, safety, and sustainability. Carbon dots (CDs), as a class of nanomaterials, have emerged with unique properties, making them innovative functional agents in food packaging. This chapter explores the diverse roles of CDs in revolutionizing food packaging by enhancing safety, extending shelf life, and contributing to sustainability. CDs, characterized by water dispersibility, stability, biocompatibility, and low toxicity, are well-suited for integration into food packaging. This chapter provides an extensive exploration of various synthesis methods employed in the creation of CDs, offering insights into their principles, advantages, and applications. The synthesis methods of CDs, such as hydrothermal synthesis, microwave irradiation, and chemical oxidation, are extensively explored, providing insights into their principles and applications. The tunable optical and electrical properties of CDs enable customization for functions like real-time monitoring and antimicrobial action. The antimicrobial and luminescent properties of CDs fortify packaging materials against microorganisms and introduce intelligence to packaging, empowering consumers with informed choices and reducing food waste. In conclusion, CDs emerge as dynamic protagonists, shaping the future of food packaging with innovation, convenience, safety, and sustainability in a concise narrative that aligns with modern lifestyles.
