                                Over 75% of the world's carbohydrate-based food supply is derived from starch-rich sources like cereals, tubers, and legumes. To identify which foods contain this vital energy source, scientists and students rely on a simple yet effective chemical indicator: iodine solution. This reliable test, known as the iodine-starch test, leverages a unique molecular reaction to produce a distinct color change.
