关于葡萄糖异构化过程中DE值下降原因的探讨

从还原力的角度探讨了葡萄糖异构化生产果葡糖浆过程中葡萄糖值下降的原因，研究了异构化过程中DE值与果糖含量的关系。结果表明，由于果糖的还原力比葡萄糖低，葡萄糖值随异构化所产生的果糖含量增加而降低，因此，葡萄糖异构化过程中DE值下降属于正常现象。

The reducing capacity of glucose, fruciose and their mixture was compared. The reason of DE dropping in the process of glucose isomerization was investigated The results showed that the reducing capacity of fructose is lower than glucose. So when glucose isomerized the DE dropped with the increasing of fructose and decreasing of glucose.
