Here, we developed a multinetwork bioactive aerogel loaded with theaflavins through the synergistic assembly of gelatin, Mg2+, glycyrrhizic acid, and theaflavins. The GGM-TF0.1 aerogel, containing 0.1% theaflavins, exhibited enhanced mechanical strength, high porosity (89.42%), and excellent water absorption capacity (949.7%). It enabled the sustained release of active compounds in food microenvironments of different polarities and showed significant antibacterial activity against Pseudomonas fluorescens and Staphylococcus aureus, together with strong antioxidant performance. When applied as an absorbent pad for mutton and pork preservation, GGM-TF0.1 slowed spoilage in mutton and pork over 12 days of refrigerated storage, as reflected by lower TVC, TBARS, and TVB-N levels, delayed pH increase, reduced color deterioration, and improved visual appearance. These results demonstrate the potential of theaflavin-loaded hydrocolloid aerogels as active absorbent pads for refrigerated meat preservation.<\/jats:p>","DOI":"10.1021\/acs.jafc.6c09006","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T06:02:18Z","timestamp":1789538538000},"page":"30372-30384","source":"Crossref","is-referenced-by-count":0,"title":["Sustained Theaflavin-Releasing\nMultinetwork Aerogel\nAbsorbent Pads with Antioxidant and Antibacterial Activities for Meat\nPreservation"],"prefix":"10.1021","volume":"74","author":[{"given":"Kaiyuan","family":"Su","sequence":"first","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Liu","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lin","family":"Yang","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-2916-3925","authenticated-orcid":true,"given":"Bingzhi","family":"Li","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuoran","family":"Guo","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yajie","family":"Wang","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2879-9489","authenticated-orcid":true,"given":"Jianlong","family":"Wang","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0903-3306","authenticated-orcid":true,"given":"Wentao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , 22 Xinong Road , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuo","family":"Shi","sequence":"additional","affiliation":[{"name":"Northwest A&F University , , , ,","place":["Yangling, Shaanxi, China, 712100"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"key":"2026093009081741100_cit1","doi-asserted-by":"publisher","first-page":"138755","DOI":"10.1016\/j.foodchem.2024.138755","article-title":"Critical review and recent advances of emerging real-time and non-destructive\nstrategies for meat spoilage monitoring","volume":"445","author":"Chen","year":"2024","journal-title":"Food\nChem."},{"key":"2026093009081741100_cit2","doi-asserted-by":"publisher","first-page":"101194","DOI":"10.1016\/j.fpsl.2023.101194","article-title":"Antibacterial absorbent\nmat based on oxidized bacterial nanocellulose for chilled meat preservation","volume":"40","author":"Tian","year":"2023","journal-title":"Food Packag.
