A thickening agent is a substance used in cooking and food preparation to increase the viscosity of liquids, making them thicker and more stable. Common examples include cornstarch, gelatin, and xanthan gum. These agents help improve the texture of sauces, soups, and desserts, enhancing the overall eating experience. In addition to culinary uses, thickening agents are also found in various industrial applications, such as cosmetics and pharmaceuticals. They play a crucial role in creating products with the desired consistency, ensuring that they are easy to apply or consume.
