摘要
首先对乳糖异构生产乳果糖的异构剂进行筛选,选出最佳异构剂为亚磷酸氢二钠,然后对异构条件进行优化,得出乳糖异构生产乳果糖最佳条件为:异构剂加量为2.0%,反应时间为3 h,反应温度为110℃,乳糖浓度为70%,在上述最佳条件下得到异构混合液中乳果糖含量为56.84%。
Firstly, the agent thatisomerized lactose to lactulose was selected, the best isomerizing agent was disodium hydrogen phosphite, secondly, the isomerization conditions were optimized, the best isomerization conditions were as follows： the quantity of isomerization agent was 2.0 %, the reaction time was 3 h, the temperature of reaction was 110 ~C, the concentration of lactose was 70 %, in the above conditions, the content of lactulose in reaction mixture reached 56.84 %.
