Caption: Iodine starch test on a potato. Footage of a demonstration of an experiment using iodine to test for the presence of starch in foods such as potatoes. If the iodine solution (orange) turns black, this is a positive result for starch. Starch is a carbohydrate that is used by plants as a store of energy, and hence is a source of energy in many plant-based foods. This test can be used on a range of starch-containing foods.
