Food tests
  1. Protein
    1. Biurets solution
      1. If protein is present it will turn from pale blue to lilac
      2. Reducing sugar
        1. Benedict's Solution
          1. Add Benedict's, heat to 80˚C. If reducing sugar present, from blue to brick red/orange-red
          2. Starch
            1. Iodine solution
              1. If present it will turn from yellow to blue-black

                  1. Mix in ethanol. Pour into water. If an emulsion forms a lipid is present
                  2. Non-reducing sugar
                    1. Benedict's solution
                      1. If reducing sugar test is negative, boil with hydrochloric acid, cool and neutralise with sodium hydrogencarbonate. Repeat Benedict's test.
                      2. Measuring concentration of glucose in a solution using COLORIMETRY
