摘要
K-卡拉胶和纳米微晶纤维素(CNC)共混时可以得到凝胶多糖。多糖总质量分数为1%,K-卡拉胶与纳米微晶纤维素的比例为9∶1时,可达到协同相互作用的最大值。研究了pH值和体系盐离子浓度对凝胶强度的影响,并通过FT-IR光谱和Raman光谱对这两种多糖之间的相互作用机理进行了初步的探讨。
Mixing of K-carrageenan with cellulose nanocrystals （CNC） can form gel. A maximum synergistic interaction occurred when the mixed ratio of K-carrageenan and cellulose nanocrystals （CNC） was 9：1 at total mass fraction 1% polysaccharide concentration. Effects of pH value and salt ion concentration on gel strength were studied. Interaction among molecules of these two polysaccharides was also investigated by FF-IR and Raman spectrometry.
