Multifunctionality of Carbon Dots Additives in Food Packaging Materials

Abstract/Preface

Carbon-based nanoparticles or CDs, with their unique structure and fascinating properties, have emerged as a standout in the field of carbon-based nanomaterials. Carbon Dots are noted for their exceptional emission of light at a shorter wavelength than the excitation light, minimal harmful effects on living organisms, compatibility with living tissues, ability to withstand prolonged exposure to light, wavelength of fluorescence emitted by a material can be adjusted or controlled according to specific needs or conditions, also ability to facilitate electrons to move from one molecule or material to another through light energy. Therefore, carbon dots benefit industry of food. They are utilized as packaging materials to prolong shelf life and maintain food safety. Carbon dots possess desirable physical and chemical properties due to their small size, diverse surface chemical groups, non-toxicity, excellent compatibility with biological systems, and notable antibacterial and antioxidant properties. They are also cost-effective and easy to synthesize. Their applications in advanced, the focus will be on exploring active, smart, and biodegradable packaging. Given their lightweight construction and high efficiency nanostructures, carbon dots offer a viable alternative to non-biodegradable plastic packaging materials. The carbon dots enhance the, chemical, and several otherpackaging characteristics being active element, without introducing any adverse effects. Consequently, CDs are effectively utilized across by various industries to extend the shelf life of food, including the application of coating agents, the use of smart packaging technologies, the implementation of active packaging solutions, and the incorporation of additives at the nano level.
