高压CO2—水混合体系水解菊粉制备果糖工艺（High Pressure CO2?—Water System for Inulin Hydrolysis to Produce Fructose）
菊粉 高压CO2—水混合体系 水解
2009/9/11
为了解决利用传统酸水解菊粉制备果糖工艺的缺点，采用高压CO2—水混合体系代替普通酸性水溶液，研究了菊粉在该体系中的水解情况，考察了CO2压力、反应温度和反应时间对菊粉水解制备果糖的影响。结果表明，菊粉的水解度随CO2压力的增大、反应时间的延长而增大，随反应温度的升高先增大而后下降。在反应压力为20?MPa、反应温度为70℃、反应时间为3h的条件下，菊粉的水解度达94.9％，说明菊粉在高压CO2—水...
