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.
