What it is

Silicon dioxide is a naturally occurring compound made of silicon and oxygen. It is commonly found in sand and quartz. For food use, it is manufactured synthetically.

Why it's used

Silicon dioxide is used as an anti-caking agent, meaning it helps prevent powdered foods from clumping together. This keeps ingredients like salt, spices, and seasoning mixes free-flowing. It is often found in dry mixes, powdered sugar, and grated cheeses.

Health notes

Silicon dioxide is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as an anti-caking agent. International bodies like the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have also evaluated silicon dioxide. At the levels typically found in food, it is not expected to cause adverse health effects.

Allergen info

Silicon dioxide is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
