Nanotechnology in edible films and its future directions: A short review
Main Article Content
Abstract
The crucial role of food packaging in protecting and containing foodstuffs has long been recognized. However, with the rising awareness of health and environmental concerns, traditional synthetic polymers are facing increasing scrutiny. This has led to exciting advancements in the field of nanotechnology, where nanoparticles are being incorporated into packaging materials to enhance food quality. These nanoparticles offer significant advantages, including antimicrobial activity and improved UV protection, thereby extending shelf life and reducing food waste. However, the need for more sustainable and biodegradable alternatives remains paramount. Edible films, crafted from natural polymers, have emerged as a promising solution, replacing conventional plastics with an eco-friendly and renewable option. These films have the potential to revolutionize food packaging, offering improved properties that enhance storage life and ensure food safety. The development of edible films derived from food biopolymers has garnered significant research interest in recent years. This review offers a thorough analysis on edible films, exploring their functional properties and the potential of nano-fillers to further enhance their performance within food packaging systems. Highlighting the classifications of bio-based polymers and Nanofillers. Additionally, impact of Nanofillers on the several functional characteristics (like physical and mechanical) of films based on biopolymers are also discussed. Furthermore, the review highlights the futuristic prospect of of Nanotechnology in edible food packaging films.
