Names of common food anti-caking agents found on product labels include: calcium silicate, iron ammonium citrate, silicon dioxide, and magnesium carbonate (high purity magnesium carbonate is used also as an antacid).
Food anti-caking agents keep powdered products free-flowing, and prevent moisture absorption. Hence, Morton Salt’s slogan “When it rains it pours” meaning that their salt will still flow out of its container even when there's moisture in the air.
Examples of uses for food anti-caking agents include salt, baking powder, and confectioners sugar.
