What happens if you add iodine to potato?

How can an iodine stain be used to distinguish between ripe and unripe fruit?
If you add Iodine-KI reagent to foods containing - starch such as bread, potato, crackers, or flour. A blue-black color results.If starch is not present, then the color will stay orange or yellow. (Iodine will not turn blue-black on contact with cellulose or disaccharides such as sucrose in sugar).Thus if you apply Iodine to an unripe fruit (where the sugars are still held as starch) the fruit will turn Blue-Black.However, once the fruit is ripe and the starch has been transformed into sweet sugar, the application of Iodine will only stain the fruit orange or yellow.

What happens if you add iodine drops to a non-starch?
If you add iodine drops to a non-starch substance, such as sugar or protein, there will be no color change. Iodine is used to detect the presence of starch by turning blue-black in the presence of starch molecules. Non-starch substances will not produce this color change.

Add a drop of iodine to both a distilled water test tube and to the test tube containing the starch solution in the test tube What do you observe?
The starch solution will turn black, while the distilled water will remain brown, the same colour as the iodine. This is actually because water, normally used as a control, does not contain any starch and as we know, the iodine test is highly specific for the presence of starch hence no colour change other than iodine dissolving in water to form an iodine solution contrary to starch which we know complexes with iodine, to form starch-iodine complex forming the blue-black colour observed
