Starch is a soft, white, tasteless powder that is insoluble in cold water, alcohol, or other solvents. If the potato has a high moisture and low solids content, the fries will become limp if held before serving because of steam captured beneath the sealed surface. That heat in a potato will then cause various chemical reactions to occur, the three most important ones are: Softening of the potato, the cellular structure breaks down, just as happens for other vegetables. Each grain is composed of molecules of starch and pectins that chemically are linked together. Acrylamide — a chemical suspected of causing cancer — forms in some foods when they’re fried, baked, toasted or roasted at high temperatures. It will cause the starch to form a firm gel and prevent separation. An internal temperature of 208°F to 211°F is the test for doneness.

The chemicals zinc and copper (in the screw and penny/wire) react with each other, which produces chemical energy. A potato with small grains such as a round white, will stay firm and waxy, while an Idaho® Russet Burbank with large grains and high starch content, will cook to a characteristically light, fluffy texture. This process of starch-grain bonding is called gelatinization, and can differ in potato varieties, depending on the size and amount of starch. This gives it several advantages in its mass use to nourish crops.
