| 摘 要： | 研究机械活化预处理对木薯淀粉氧化产物理化性质的影响。采用搅拌球磨机对木薯淀粉进行机械活化，以不同活化时间的木薯淀粉为原料，CuSO4为催化剂，H2O2为氧化剂干法制备氧化淀粉，对由不同活化时间木薯淀粉制备的氧化淀粉的溶解度、表观黏度、透明度、冻融稳定性、凝沉性等性质进行研究。试验结果表明：机械活化预处理对木薯淀粉氧化产物的理化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: | Study on effect of mechanical activation pretreatment on physicochemical properties of cassava starch oxidation products.Cassava starch was activated mechanically with a stirring-type ball mill.Using H2O2 as oxidant and CuSO4 as catalyst,the oxidized starch was prepared by dry method with different activated times.The properties(solubility,apparent viscosity,diaphaneity,freeze-thaw stabilization,retrogradation) of the oxidized cassava starch produced of different activated times were studied.Experimental re... |
