摘要

对生物基材料的可再生和环保型原材料的追求是一个不断增长的领域。本研究利用从红毛丹皮废弃物中提取的鞣花丹宁和纤维素微纤维与明胶一起开发具有生态意识的水凝胶。以两种重量比（0.5:1 至 1:1）配制纤维素/明胶水凝胶，并研究了明胶对化学成分和流变学的影响。富含鞣花丹宁提取物的功能化复合水凝胶的抗压强度显著提高了 14 倍。从红毛丹果皮废弃物中提取的水凝胶具有生物相容性，可用于药物输送系统和伤口敷料等生物医学应用。这表明它可能为可持续材料科学提供重要价值，尽管具体应用还有待测试。

Integrating Cellulose Microfibrils and Ellagitannins from Rambutan Peel with Gelatin for Production of Synergistic Biobased Hydrogels

The pursuit of renewable and eco-friendly raw materials for biobased materials is a growing field. This study utilized ellagitannin and cellulose microfibrils derived from rambutan peel waste alongside gelatin to develop eco-conscious hydrogels. The cellulose/gelatin hydrogels were formulated in two weight ratios (0.5:1 to 1:1), and the influence of gelatin on the chemical composition and rheology was studied. Composite hydrogels, functionalized with an ellagitannin-rich extract, exhibited a remarkable enhancement of up to 14-fold in compressive strength. The hydrogels also demonstrated antimicrobial properties, reducing the Staphylococcus aureus colony count within 24 h. The hydrogel, derived from rambutan peel waste, is biocompatible and could potentially be explored for biomedical applications such as drug delivery systems, and wound dressings. This suggests that it might offer significant value for sustainable materials science, although specific applications have yet to be tested.
