THE IODINE TEST

AIM - To test is a sample of food contains complex sugars.

METHOD - 1) place about 2 ml of the sample in a test tube
                     2) Add 3-5 drops of iodine mix

RESULTS - If complex sugars (i.e. starch) are present the iodine solution will change from a brown colour to a blue/black colour.

DISCUSSION - It changed colour so the bread (food sample) does contain complex sugars
