摘要: 以玉米淀粉为原料,三偏磷酸钠为交联剂,制备轻度交联淀粉,探讨三偏磷酸钠用量、pH值、反应温度、反应时间对交联度(即沉降体积)的影响;并采用正交试验设计进行优化,确定最佳工艺条件为:三偏磷酸钠用量为淀粉干质量的1.5%、反应时间1.5h、反应pH10.25、反应温度50℃。

Abstract: This study aimed at preparation of cross-linked corn starch with sodium trimetaphosophate as cross-linking agent. Effects of sodium trimetaphosophatethe amount,pH,reaction temperature and time on degree of cross-linking were studied. Results showed that the optimal conditions for preparing cross-linked corn starch are sodium trimetaphosophate amount 1.5%,pH 10.25,reaction time 1.5 h and temperature 50 ℃.

Key words: sodium trimetaphosophate, cross-linked, corn starch, preparation technology
