Chinese Abstract

[目的]分析和研究兰-艾农法测定甘蔗汁还原糖时加铅液量(澄清剂)和脱铅剂量对后续测定的影响。[方法]分别设立不同的处理,加铅量为1.0、1.5、2.0、2.5、3.0 ml,脱铅剂量为1.0、1.5、2.0、2.5、3.0 ml,测定不同处理下的还原糖含量。[结果]加铅量在1.0 ml时,测出的还原糖值最低;加铅量在1.5 ml时,测出的还原糖含量明显增高;而加铅量在2.0~3.0 ml时,随加铅量的增加还原糖测定结果是渐续增大的。脱铅剂加入量大,试验最后结果变小。[结论]加铅量在1.5~2.0 ml比较合适;脱铅剂量在2.0~2.5 ml比较合适。

English Abstract

[Objective] This paper aims to study the quantity of plumbum (clarifier) and the quantity of deleading reagent influencing the follow-up process of reducing sugar in sugar cane juice determination using Lane-Eynong method. [Method] Treatments of different quantity of plumbum (1.0 ml, 1.5 ml, 2.0 ml, 2.5 ml, 3.0 ml) and different quantity of deleading reagent (1.0 ml, 1.5 ml, 2.0 ml, 2.5 ml, 3.0 ml) are established so as to test the reducing sugar amount under different treatments. [Result] The lowest level of reducing sugar is obtained with 1.0 ml plumbum. When the quantity of plumbum is 1.5 ml, the higher level of reducing sugar is obtained. There had no remarkable increase when the quantity of plumbum is between 2.0 ml and 3.0 ml. Lower level of reducing sugar is resulted with higher quantity of deleading reagent. [Conclusion] The suitable quantity of plumbum is from 1.5 ml to 2.0 ml and the suitable quantity of deleading reagent is from 2.0 ml to 2.5 ml.
