研究了微波条件下酸解菊粉的方法制备果糖,采用单因素试验研究了菊粉浓度,温度,pH值,反应时间对微波条件下酸解菊粉制备果糖的影响,再通过正交优化试验确定了菊粉水解的最佳工艺条件：菊粉浓度15%,温度为55℃,溶液pH值为5,微波辐照时间15 min,在该条件下果糖产率高达92.3%。与传统加热工艺相比,微波条件下酸解菊粉制备果糖,反应速率快、能量消耗少、所用的酸量也大大降低、副反应少,目标产物收率提高。

Inulin hydrolyzed by acid-catalyzed under microwave irradiation was researched and its operating conditions were optimized. The fructose production under microwave irradiation was studied from concentration of inu-lin, temperature, pH value, and reaction time. The optimum reaction conditions were:inulin solution 15%, temper-ture 55℃, pH 5 and reaction time 15min. Under those conditions above, the yield of fructose production was 92. 3%. Compared with conventional heating technics, micorwave irradiation not only accelerate acid hydrolysis of inu-lin, but also decrease the by-product and result in a higher yield.
