WebFehling’s test is one of the most common tests used for the identification of reducing and non – reducing sugars. Fehling’s test is an indicating reaction for reducing groups like Aldehyde functions. The principle of this test is based on the fact that the aldehyde group of sugar is oxidised to form acids by complex Copper ions.
