Choline chloride and urea were used as the NADES system combined with ultrasound to extract flavonoids from <em>Dalbergia pinnata</em> (Lour.) Prain (DPF), which are directly incorporated into a Gelatin/Chitosan (Gel/CS) matrix to prepare deep eutectic composite films (GCD1–4) by solution casting. This extract simultaneously serves as a homologous plasticizer and functional agent. It avoids the repeated addition of plasticizers, antibacterial, and antioxidant agents, which are commonly required in conventional film preparation. The results show that with increasing DPF content, the films transformed from “rigid and brittle” to “flexible”, the surface wettability shifted from hydrophilic to hydrophobic, water solubility significantly decreased, and UV shielding ability was enhanced. The GCD-2 film show antibacterial efficiencies of 73.37 ± 4.94 % and 96.78 ± 0.2 % against <em>Staphylococcus aureus</em> and <em>Escherichia coli</em>, respectively. Its DPPH and ABTS radical scavenging rates were 69.74 ± 0.67 % and 99.08 ± 0.9 %, respectively, demonstrated good antibacterial and antioxidant activities. Cell viability was close to 100 %, and the hemolysis rate was below 5 %, indicates good biocompatibility of the films. Furthermore, the GCD series of films demonstrated good biodegradability, indicates their strong environmental friendliness. In application tests, the GCD-2 film significantly reduced weight loss, browning, and decay in strawberries and apple slices, effectively inhibiting decay, and shows the best preservation effect. In conclusion, the Gel/CS/DPF composite films achieved synergistic “plasticization-antibacterial-antioxidation” effects through the green extract, demonstrating great potential as biodegradable active packaging materials for fruit preservation.</div></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":"54 ","pages":"Article 101717"},"PeriodicalIF":10.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 functions. Small aerogel labels have been used as ethylene adsorbents, moisture and impurity scavengers, and intelligent colorimetric indicators capable of responding to pH changes or volatile amines for real-time freshness monitoring. Large aerogel pads function as superabsorbent elements for exudates, carriers for the controlled release of antimicrobial or antioxidant agents, cushioning pads for mechanical protection, and lightweight insulation components suitable for chilled or frozen foods. These emerging applications illustrate the versatility of biopolymer aerogels while also revealing challenges such as limited wet stability, regulatory barriers for active components, and the high cost of scalable fabrication. By structuring current knowledge around packaging format and functional roles, this review provides a consolidated and application-oriented overview of the practical potential, limitations, and future opportunities of biopolymer aerogels in next-generation intelligent and active food-packaging systems.</div></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":"54 ","pages":"Article 101726"},"PeriodicalIF":10.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385500","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proteins such as gelatin offer excellent film-forming ability but suffer from brittleness, while polysaccharides like xanthan gum contribute flexibility and stability across variable conditions. Microcrystalline cellulose, with its reinforcing effect, further improves water resistance and mechanical strength. Despite the potential of these complementary biopolymers, most studies focus on formulations prepared by casting, a process simple but difficult to scale up. Little is known about how industrially relevant methods such as extrusion affect the structure and functionality of gelatin, xanthan gum, cellulose composites. This study addresses this gap by comparing films produced by casting and extrusion using a polymer matrix of gelatin, xanthan gum, and varying cellulose concentrations (2.5, 5.0, and 10.0 %). Casting resulted in films with a tensile strength 200 % higher than extruded ones, while extrusion led to an 800 % increase in elongation and yielded hydrophobic films (contact angle &gt; 90°). All materials displayed amorphous structures and similar thermal stability, regardless of cellulose concentration. Overall, our findings demonstrate that the processing route is a decisive factor in defining the functionality of bio-based films. By showing how extrusion can be leveraged to tailor flexibility and surface properties, this work provides valuable insights for advancing scalable and high-performance alternatives to fossil-based plastics in sustainable food packaging.</div></div>","PeriodicalId":12377,"journal":{"name":"Food Packaging and Shelf Life","volume":"54 ","pages":"Article 101721"},"PeriodicalIF":10.6,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146171422","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
