en Production and Evaluation of Chitosan-Collagen Nanocomposite Packaging Film from Chicken Feet Waste تخصصي Special Original article Original article <div style="text-align: justify;">Background: Annually, approximately 3.9 million metric tons of chicken feet are produced. As a common poultry by-product, they are a rich collagen source, representing over 40% of total amino acids. To maximize their potential, innovative utilization is required to enhance their value. The study aimed to investigate the use of broiler chicken feet for producing acid-hydrolyzed collagen and incorporating it into chitosan-collagen composite films, including nanocomposite films. Methods: Chitosan film, chitosan-collagen composite film, and chitosan-collagen nanocomposite film were prepared. Physical, mechanical, antioxidant, and antimicrobial properties of these composite films were evaluated and compared to identify the most suitable material for food packaging. Results: Chitosan-collagen nanocomposite film demonstrated favorable characterizations, including mechanical, physical, antioxidant, and antimicrobial properties, in addition to lower oxygen permeability than other films. Conclusion: Chitosan-collagen nanocomposite film is suitable as a packaging material for preservation purposes, especially in animal-based or high-fat foods.
