In lab, we used Benedict's reagent to test for one particular reducing sugar: glucose. Benedict's reagent starts out aqua-blue. As it is heated in the presence of reducing sugars, it turns yellow to orange. The "hotter" the final color of the reagent, the higher the concentration of reducing sugar.

What does Benedict test detect?

A positive test with Benedict's reagent is shown by a color change from clear blue to brick-red with a precipitate. Generally, Benedict's test detects the presence of aldehydes, alpha-hydroxy-ketones, and hemiacetals, including those that occur in certain ketoses.

What food does Benedict's solution test for?

Reducing sugars are detected using Benedict's solution . Reducing sugars include: monosaccharides – such as glucose and fructose. disaccharides – such as maltose.
