Iodine starch test on a potato. Close-up footage of a cut potato that is being tested with iodine for the presence of starch. If the iodine solution turns from orange to black (as here), this is a positive result for starch. This test can be used on a range of starch-containing foods. 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. | |
