【摘要】 以玉米淀粉为原料,采用新工艺制备出预糊化淀粉。并对糊化温度、糊化时间、pH值、淀粉浆质量分数以及脱水过程中乙醇加入量对预糊化淀粉粘度的影响进行了研究。通过正交实验,确定出制备预糊化淀粉的最佳工艺参数为:糊化温度95℃,糊化时间3 h,pH值为8,淀粉浆质量分数5%。更多还原

【Abstract】 The pre-gelatinized starch was prepared from cornstarch by a new technology.The effects of reaction temperature,reaction time,pH value,starch syrup mass fraction and addition amount of ethanol in the dehydration process on the viscosity of pre-gelatinized starch were studied.The following optimum conditions were obtained by orthogonal designs: reaction temperature 95℃,reaction time 3 h,pH value 8 and starch syrup mass fraction 5%.更多还原
