What it is
Sodium silicoaluminate is a synthetic compound made from aluminum, silicon, and sodium. It is produced by reacting sodium aluminate with sodium silicate under controlled conditions.
Why it's used
Manufacturers add sodium silicoaluminate to powdered foods to prevent clumping and caking. It works by absorbing moisture and coating particles, keeping them free-flowing. It is commonly found in dry mixes like gravy, spices, and powdered sugar.
Health notes
In the US, sodium silicoaluminate is generally recognized as safe (GRAS) by the FDA for use as an anti-caking agent. International bodies like JECFA have also evaluated it. At the levels typically used in food, it is not expected to cause adverse health effects. There is no widespread controversy regarding its safety.
Allergen info
Sodium silicoaluminate is not derived from any of the nine FDA major allergens. It does not contain gluten.
