摘要
对碎米麦芽糖加氢制备麦芽糖醇的氢化工艺进行研究。试验结果表明氢化过程的最佳工艺条件为:氢化压力10MPa,氢化温度130℃,pH值9,催化剂用量8%,氢化时间120min,麦芽糖浓度为30%。在此条件下,测得碎米麦芽糖转化为麦芽糖醇的转化率为45.17%。
The technology for preparation of maltitol from broken-rice maltose by hydrogenation was studied. Results showed that the optimum hydrogenation technology condition is: hydrogenation pressure 10 MPa, hydrogenation temperature 130 ℃ , pH 9, the amount of catalyst 8 %, hydrogenation time 120 min, maltose concentration 30 %. Under this condition, the ratio of broken-rice maltose to maltitol reached 45.17 %.
