Recent advances in biopolymer aerogels for food packaging: A design perspective across different formats

Biopolymer aerogels have increasingly been explored as functional components in food packaging systems, where lightweight structures, moisture management, active protection, and intelligent sensing are required. This review summarizes recent progress by categorizing aerogel applications into two major packaging formats: small aerogel labels and large aerogel pads or inserts. This organizational perspective differs from previous reviews that primarily focus on material types. We compile advances in polysaccharide- and protein-based aerogels, including systems derived from cellulose nanostructures, starch, chitosan, and whey proteins, and highlight how these materials are applied across distinct packaging…
