Four classes of corn starch exist. Common corn starch has 25% amylose, while waxy maize is almost totally made up of amylopectin. The two remaining corn starches are high-amylose corn starches; one has 55% to 55% amylose, while the second has 70% to 75%. Potato. Potato starch has about 20% amylose. Like those from many tubers, potato starch granules are large with a smooth round oval shape. Of the starches commonly used for food, potato starch is the largest; its granules range in size from 15 to 75 microns.
