Abstract:
Aerogel is a material with a three-dimensional, porous structure formed by the sol-gel method and specific drying means, which is a specific functional material due to the unique structure of aerogel itself. Chitosan has been widely used in many fields, such as biomedicine, agriculture, and environmental management, due to its excellent biological properties. In recent years, aerogel materials prepared from chitosan have shown great research potential in the food industry due to their controllable physical and chemical properties, good biological activity, and environmentally friendly characteristics. This paper provides a comprehensive review of the preparation methods, characterization techniques, and applications of chitosan-based aerogels in the food field. This review underscores the significance of chitosan-based aerogels in advancing sustainable and functional food materials, discusses the current challenges of chitosan-based aerogels in terms of large-scale production and provides valuable insights for future research and development in the food industry.
