- Test For Reducing Sugars - 

Test for reducing sugars:

All monosaccharides and some disaccharides are reducing sugars. A reduction reaction is a chemical reaction involving the gain of electrons or hydrogen. Reducing sugars that can donate electrons to another chemical. Reducing sugars can be tested for using Benedict's reagent which is an alkaline solution of copper II sulphate. An insoluble red precipitate of copper oxide is formed when reducing sugars are heated with benedict's reagent.

Methods:

1. Add 2cm³ of the food sample to be tested to be tested to the test tube (this should be in liquid form).
2. Add an equal volume of Benedict's reagent.
3. Heat the mixture in a gently boiling water for 5 minutes.
