【摘要】 <正>卡拉胶是一系列从不同的海洋红藻中提取的线性水溶性多糖的统称。κ-卡拉胶是由β(1→ 3)-D-半乳糖-4-硫酸基和α(1→4)-3,6-内醚-D-半乳糖形成的交替共聚物。它常被用作增稠剂、胶凝剂、结构增强剂和稳定剂,用于食品、制药和化妆品工业。纳米微晶纤维素(cellulose nanocrystals,CNC)可通过天然纤维素或微晶纤维素经强酸降解而制得。它和纤维素一样是更多还原

【Abstract】 Mixed κ-carrageenan and cellulose nanocrystals can form gel. A maximum synergistic interaction occurred when the mixed ratio of κ-Carrageenan and cellulose nanocrystals was 9/1 at the total 1% (mass fraction) polysaccharide concentration. Effects of salt ionic concentration and the pH on the gel strength have been studied in this paper.更多还原
