Potato starch is a fine, white powder derived from the tubers of the potato plant. It is primarily composed of carbohydrates and is commonly used as a thickening agent in cooking and baking. When heated with liquid, potato starch forms a gel-like consistency, making it ideal for sauces, soups, and puddings. In addition to its culinary uses, potato starch is also utilized in various industrial applications, such as in the production of biodegradable plastics and as a binding agent in food processing. Its gluten-free nature makes it a popular choice for those with gluten sensitivities or celiac disease.
