Silicon dioxide, also known as silica, is a natural compound made up of silicon and oxygen. It is commonly found in nature in the form of quartz or as a major component of sand, as well as in rocks and soil. In the food industry, silicon dioxide is used as an anti-caking agent, meaning it helps prevent clumping in powdered products such as protein powders. It is also used as a stabilizer and thickener in a variety of foods, including beverages, sauces, and dressings.
Silicon dioxide is generally recognized as safe by regulatory agencies and is commonly used in food products.
