Silicon Dioxide Added To Prevent Caking

Silicon dioxide is a naturally occurring compound made of silicon and oxygen. It is also known as silica. It is commonly found in sand and quartz and can be manufactured for use in food.

Manufacturers add silicon dioxide to powdered foods to prevent clumping and caking, ensuring a free-flowing product. It acts as an anti-caking agent. It is often found in spices, salt, powdered drink mixes, and baking powder.

Silicon dioxide is generally recognized as safe (GRAS) by the FDA for use as an anti-caking agent. International bodies like JECFA and EFSA have also evaluated it. At typical levels used in food, it is not expected to cause adverse health effects. Evidence does not suggest significant health concerns.
