Corn starch is a fine, white powder made from the endosperm of corn kernels. It is commonly used as a thickening agent in cooking and baking, helping to create smooth sauces, soups, and puddings. Additionally, it can be used in various food products to improve texture and stability. In addition to culinary uses, corn starch has applications in industries such as pharmaceuticals and cosmetics. It can serve as a filler in tablets and a moisture-absorbing agent in powders. Its versatility makes it a valuable ingredient in both food and non-food products.
