中文摘要: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3h的条件下,菊粉的水解度达94.9%,说明菊粉在高压CO2—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 first followed by decreasing with reaction temperature rise. Under an optimum reaction condition of CO2 pressure 20MPa, reaction temperature 70℃ and reaction time 3h, the hydrolysis degree of inulin reached 94.9%, which implies that the inulin is efficiently hydrolyzed to produce fructose in the high pressure CO2—water system, and the complicated operations and pollution of the traditional acid hydrolysis process were avoided. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
