    Food Test 2: Protein - Biuret solution

    Biuret solution is used to identify the presence of protein. Biuret reagent is a blue solution that, when it reacts with protein, will change color to pink-purple.

    What to do.

    To a test tube, add 40 drops of liquid to be tested.

    If testing more than one liquid, label each test tube with a marker.

    Add 3 drops of Biuret reagent solution to each test tube. Shake gently to mix.

    Note any color change. Proteins will turn solution pink or purple.
