Synergistic construction of low-temperature-resistant, water-retaining, and cushioning hydrogels via 1-s UV curing and ethylene glycol annealing for postharvest fruit protection.
Hydrogels are promising cushioning materials for fresh produce packaging because of their viscoelasticity, deformability, and energy-dissipation capability. In this study, a UV-curable hydrogel based on methacrylated hyaluronic acid (HAMA) was developed. Through ethylene glycol (EG) annealing, a cushioning material (HA...
