Abstract:
In this work, effects of cellulose nanofiber/dihydromyricetin (CNF/DMY) ratio on the structural, antioxidant and emulsifying properties of the CNF/DMY mixtures were investigated. CNF integrated with DMY via hydrogen bonding and the antioxidant capacity of mixtures increased with decreasing CNF/DMY ratio (k). The oxidative stability of emulsions enhanced as the DMY content increased. Emulsions formed at Φ = 0.5 displayed larger size (about 25 μm), better viscoelasticity and centrifugal stability than those at Φ = 0.3 (about 23 μm). The emulsions at k = 17:3 and Φ = 0.5 exhibited the most excellent viscoelasticity. In conclusion, the DMY content in mixtures and the oil phase fraction exhibited distinct synergistic effects on the formation and characteristics of emulsions, and the emulsions could demonstrate superior oxidative and storage stability. These findings could provide a novel strategy to extend the shelf life of cellulose-based emulsions and related products.
摘要:
在这项工作中,纤维素纳米纤维/二氢杨梅素(CNF/DMY)比例对结构的影响,研究了CNF/DMY混合物的抗氧化和乳化性能。CNF通过氢键与DMY结合,并且混合物的抗氧化能力随着CNF/DMY比率(k)的降低而增加。乳液的氧化稳定性随着DMY含量的增加而增强。在Φ=0.5时形成的乳液显示出较大的尺寸(约25μm),比Φ=0.3(约23μm)时更好的粘弹性和离心稳定性。k=17:3和Φ=0.5的乳液表现出最优异的粘弹性。总之,混合物中的DMY含量和油相分数对乳液的形成和特性表现出明显的协同作用,乳液可以表现出优异的氧化和储存稳定性。这些发现可以提供一种新的策略来延长基于纤维素的乳液和相关产品的保质期。
