What it is

Silicon dioxide is a form of silica, which is a natural mineral. It is manufactured by reacting a silicon compound with oxygen. It is often used in a very fine powder form.

Why it's used

Manufacturers add silicon dioxide to powdered foods to prevent clumping and caking, ensuring a free-flowing product. It acts as an anti-caking agent. It is commonly found in seasoning mixes, salts, and powdered drink mixes.

Health notes

Silicon dioxide is generally recognized as safe (GRAS) by the FDA for use as an anti-caking agent. It is poorly absorbed by the body and passes through the digestive system. International bodies like JECFA and EFSA have evaluated silicon dioxide and have not set a numeric limit for its acceptable daily intake. Evidence does not suggest adverse health effects at the low levels typically consumed in food.

Allergen info

Silicon dioxide is not one of the 9 FDA major allergens and does not contain gluten.
