What it is
As a thickener, this ingredient is not a specific substance but rather a functional category. It refers to any food additive used to increase the viscosity or thickness of food products. These can be derived from natural sources like plants, animals, or microbes, or they can be synthetically produced.
Why it's used
Thickeners are added to foods to improve texture, stability, and consistency. They are commonly found in sauces, gravies, dressings, dairy products, baked goods, and desserts. Manufacturers use them to create a desired mouthfeel, prevent ingredients from separating, and enhance the overall eating experience.
Health notes
Many common thickeners are recognized as safe by the FDA. For example, starches like cornstarch and tapioca starch are generally recognized as safe (GRAS). Gums such as xanthan gum and guar gum are also widely used and considered safe. International bodies like JECFA and EFSA have evaluated many thickeners, generally finding them safe for consumption at typical levels. While some individuals may experience digestive discomfort from certain gums if consumed in very large amounts, they are not typically associated with significant health concerns for the general population.
Allergen info
Not a major allergen. Some thickeners derived from plant sources like wheat or soy may contain gluten or be allergens, but these are usually specified on the label.
