| Περίληψη: | To develop a long-lasting antimicrobial food preservation pad, a ternary composite aerogel (PKS) was prepared using pea protein isolate (PPI), konjac glucomannan (KGM), and tetraethyl orthosilicate (TEOS), with epigallocatechin gallate (EGCG) incorporated as the active compound. A PPI-to-KGM ratio of 2:1 produced an aerogel with a high specific surface area (307.60 m2/g). It also exhibited improved compressive strength and thermal stability. The EGCG loading efficiency reached 41.89%. The aerogel enabled sustained EGCG release for over 30 days and maintained strong antioxidant activity. Korsmeyer-Peppas kinetic analysis revealed that EGCG release from the aerogel was governed by Fickian diffusion.It also effectively inhibited Staphylococcus aureus. When applied to pork loin, it suppressed bacterium growth (On day 9, the total colony count was 5.61 log CFU/g.) maintained the pH at 6.57, and delayed discoloration. Overall, the crosslinked aerogel is a promising long-acting antimicrobial delivery system for active food packaging. (Copyright © 2026 Elsevier Ltd. All rights reserved.) |
