1. Aim: To compare the reducing sugar content of dry raisin and fresh grape 2. Introduction: i) Principle of Benedict’s test Reducing sugar can reduce Cu2+ into Cu+ and form a bricked-red precipitate (copper(I) oxide) which is insoluble in water. ii) Use of Benedict’s test Benedict’s test can show the presence of reducing sugar (all monosaccharide and disaccharide‚ except sucrose).
