Thickening agents are substances used in cooking and food preparation to increase the viscosity of liquids, making them thicker and more stable. Common examples include cornstarch, gelatin, and flour. These agents work by absorbing water and swelling, which helps to create a desired texture in sauces, soups, and gravies. In addition to culinary uses, thickening agents are also found in various industrial applications, such as cosmetics and pharmaceuticals. They help improve the consistency and stability of products, ensuring they perform effectively. Understanding how to use thickening agents can enhance both the flavor and appearance of dishes.
