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). Add Benedict’s solution into food samples (solution). Then mix them up and put into a water bath for 5

Food Test 1: Test for Glucose – with Benedicts solution Benedicts solution is used to test for simple sugars‚ such as glucose. It is a clear blue solution of sodium and copper salts. In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar.
