| 摘 要： | 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3 h的条件下,菊粉的水解度达94.9%,说明菊粉在高压C2-水溶液混合体系中水解可实现高效率生产果糖,避免了传统酸水解工艺复杂和污染的问题.

| Abstract: | With the aim to solve the drawback on the traditional fructose production from inulin hydrolysis in acidic aqueous solution,the high pressure CO2-water system for the inulin hydrolysis was studied instead of the traditional acidic aqueous solution.The effects of CO2 pressure,reaction temperature and reaction time on fructose production from inulin hydrolysis were investigated.The results showed that the hydrolysis degree of inulin was positively related with CO2 pressure and reaction time,and increased at f... |
