Thickeners

Thickeners are ingredients that increase the viscosity of liquids, making them thicker or more gel-like. They can be derived from natural sources like plants, animals, or microbes, or be synthetically produced. Many common thickeners are modified starches or gums extracted from sources such as corn, potatoes, seaweed, or guar beans.

Manufacturers add thickeners to improve the texture, consistency, and stability of food products. They help prevent ingredients from separating and give foods a smoother mouthfeel. Thickeners are commonly found in sauces, gravies, dressings, dairy products like yogurt and ice cream, baked goods, and processed meats.

Many common thickeners are recognized as safe by the FDA, often listed as Generally Recognized As Safe (GRAS) or approved food additives. International bodies like JECFA and EFSA have evaluated many thickeners. At typical consumption levels, they are generally considered safe and contribute dietary fiber. Some individuals may experience digestive upset if they consume very large amounts, particularly of certain types of gums.
