✔ 最佳答案
通常罐裝飲料的糖份是用光折射率來測定(brix reflectometry)因為飲料中的糖份會增加糖溶液折射率......而且罐裝飲料通常用蔗糖(cane sugar)是非還原性糖(non-reducing sugar)如果要做benedict test先要用鹽酸把蔗糖水解才可以,所以會很浪費時間!!
量度(brix reflectometry)通常用brix reflectometer-----直接看度數.......

if u want to test for reducing sugar, eg glucose, galatose, fructose, maltose etc. u can use benedict's test or Fehling's solution, it is a solution a CuSO4, these reducing sugar can reduce the Cu2+ into Cu2O.
