| 摘 要： | 采用马铃薯淀粉为原料,FeSO4为催化剂,H2O2为氧化剂干法制备氧化淀粉,对氧化淀粉溶解度及其糊的表观粘度、透明度、冻融稳定性、凝沉性等性质进行研究。结果表明,与原淀粉相比,马铃薯氧化淀粉溶解度、透明度增大,表观粘度降低,冻融稳定性增强,凝沉性减弱;并对氧化淀粉结构进行表征。

| Abstract: | Oxidized starch was prepared by dry method using the potato starch as material,H2O2 as oxidant and FeSO4 as catalyst.The properties of the starch paste,such as solubility,apparent viscosity,diaphaneity,freeze–thaw stabilization,retrogradation,were studied.The experimental results showed that the solubility and diaphaneity of oxidized starch increased,and its apparent viscosity reduced,freeze–thaw stabilization enhanced,retrogradation decreased than the native potato starch.Furthermore the oxidized starch was further characterized. |
