The two common test are Benedict’s test and Fehling’s test. Both tests employ alkaline solution of copper sulphate which is blue in colour with reducing sugar it gives orange to brick red precipitation. Galactose is a reducing sugar. It gives brownish red precipitate wiht Fehling reagent and wiht Benedict’s reagent it gives yellow, red or green precipitate confirming the presence of sugar. Sucrose, starch are non-reducing sugars.
