What it is
Silica gel is a form of silicon dioxide, a naturally occurring mineral. It is processed to be highly porous and is often manufactured synthetically for use as a food additive. It is not absorbed by the body.
Why it's used
Silica gel is used as an anticaking agent in powdered and granulated foods. It absorbs moisture, preventing ingredients from clumping together and ensuring a free-flowing product. It is commonly found in products like spices, salt, powdered mixes, and some processed seafood.
Health notes
Silica gel is generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use as an anticaking agent. International bodies like JECFA (Joint FAO/WHO Expert Committee on Food Additives) have evaluated silica gel and established acceptable intake levels. It is not known to have adverse health effects at typical consumption levels.
Allergen info
Not a major allergen. Silica gel is a mineral and does not contain any of the nine FDA major allergens or gluten.
