| 摘 要： | 采用搅拌球磨机对玉米淀粉进行机械活化,以不同活化时间的玉米淀粉为原料,CuSO4为催化剂,H2O2为氧化剂干法制备氧化淀粉。对不同活化时间玉米淀粉氧化产物的溶解度、糊的表观黏度、透明度、冻融稳定性、凝沉性等性质进行研究。结果表明,机械活化预处理对玉米淀粉氧化产物糊的性质产生显著的影响。随着机械活化时间的延长,氧化淀粉的溶解度、透明度增大,表观黏度降低,冻融稳定性减弱,凝沉性增强。

| Abstract: | The maize starch was activated mechanically by a stirring type ball mill.Oxidized starch was prepared by dry method from the different activated maize starch as a starting material,CuSO_4 as a catalyst and H_2O_2 as oxidant.Then the properties such as solubility,apparent viscosity,diaphaneity,freeze-thaw stabilization,retrogradation of the oxidized starch prepared from the different activated maize starch were studied.Experimental results showed that mechanical activation pretreatment considerably influence... |
