What it is
Anti-caking agents are substances added to powdered or granulated foods to prevent clumping. They work by coating the particles and absorbing moisture. Many are naturally occurring minerals, while others are synthesized.
Why it's used
Manufacturers add anti-caking agents to keep powdered products like spices, salt, and baking mixes free-flowing. They are also found in processed cheeses, dried soups, and some snack foods like popcorn and peanuts. Their function is to prevent moisture absorption and particle adhesion.
Health notes
Many anti-caking agents are recognized as safe by the FDA, often listed as Generally Recognized As Safe (GRAS). International bodies like JECFA and EFSA have evaluated many of these substances. Generally, they are considered safe when consumed in the small amounts typically found in food. Some studies have explored potential effects, but evidence at typical intake levels is mixed or inconclusive.
Allergen info
Most anti-caking agents are not derived from major allergens. However, some may be processed on equipment shared with allergens. Always check the product label for specific allergen warnings.
