摘　　要：目的 :直接滴定法测定总糖的方法改良。方法 :酒样水解后与费林试剂共沸 ,生成Cu2 O沉淀 ,稍微过量的还原糖将蓝色的次甲基蓝还原为无色 ,根据酒样消耗量求得总糖含量。结果 :改良直接滴定法方法更明确、结果更精确。结论 :通过实验证明改良直接滴定法有效可行 。Purpose:Improve measurement of direct titration for total glucide.Method:Make Cu_2O deposition from boiling the Hydrolyzed sample and Fehling reagent,Change Mehylene.Blue from blue to achromaticity using a little bit too much of restore reducing sugar,Measure the content of total glucide according to how mach example to be used up.Result:The new method of direct titration is more clear and definite,the result is more accurate.Conclusion:Pass experiment to proof that the betterment direct titration is validity and have generalize importance.
