Abstract:
Based on the findings of our previous studies, a comprehensive comparative investigation of the quality and formation mechanism of gels obtained from protein self-assemblies induced by different methods is necessary. Self-assembled heat-induced gels had higher gel mechanical strength, and hydrophobic interactions played a greater role. Whether or not heat treatment was used to induce gel formation may play a more important role than the effect of divalent cations on gel formation. Hydrogen bonds played an important role in all gels formed using different gelation methods. Furthermore, Self-assembled cold-induced gels were considered to can load bioactive substances with different hydrophilicity properties due to the high water-holding capacity and the smooth, dense microstructure. Therefore, β-lactoglobulin fibrous and worm-like self-assembled cold-induced gels as a delivery material for hydrophilic bioactive substances (epigallocatechin gallate, vitamin B2) and amphiphilic bioactive substance (naringenin), with good encapsulation efficiency (91.92 %, 97.08 %, 96.72 %, 96.52 %, 98.94 %, 97.41 %, respectively) and slow-release performance.
摘要:
根据我们以前的研究结果,有必要对不同方法诱导的蛋白质自组装凝胶的质量和形成机理进行全面的比较研究。自组装热诱导凝胶具有较高的凝胶机械强度,疏水作用发挥了更大的作用。是否使用热处理来诱导凝胶形成可能比二价阳离子对凝胶形成的影响起更重要的作用。氢键在使用不同凝胶化方法形成的所有凝胶中起着重要作用。此外,自组装冷诱导凝胶由于具有较高的保水性和光滑,致密的微观结构。因此,β-乳球蛋白纤维和蠕虫状的自组装冷诱导凝胶作为亲水性生物活性物质的递送材料(表没食子儿茶素没食子酸酯,维生素B2)和两亲性生物活性物质(柚皮素),具有良好的封装效率(91.92%,97.08%,96.72%,96.52%,98.94%,97.41%,分别)和缓释性能。
