Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. This makes a linear triiodide ion complex with is soluble. The triiodide ion ion slips into the coil of the starch causing an intense blue-black color.
Iodine added to a solution or directly on a potato or other materials such as bread, crackers, or flour will produce a blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow.
