Thickeners are substances used to increase the viscosity of liquids, making them thicker and more stable. Commonly found in cooking and food production, they help improve texture and consistency in sauces, soups, and dressings. Examples of thickeners include cornstarch, gelatin, and xanthan gum. In addition to culinary uses, thickeners are also important in various industries, such as pharmaceuticals and cosmetics. They can enhance the performance of products like creams, lotions, and medications by ensuring even distribution and stability. Overall, thickeners play a crucial role in both food and non-food applications.
