What it is
Silicon dioxide is a naturally occurring compound made of silicon and oxygen. It is found in sand and quartz. It is manufactured for food use by processes like burning silicon in oxygen or reacting silicon tetrachloride with oxygen.
Why it's used
Manufacturers add silicon dioxide as an anti-caking agent. This means it helps prevent powders from clumping together, keeping them free-flowing. It is commonly found in powdered drink mixes, spices, and shredded cheeses.
Health notes
In the US, silicon dioxide is Generally Recognized As Safe (GRAS) by the FDA. It is approved for use as an anti-caking agent. International bodies like JECFA and EFSA have also evaluated silicon dioxide. At typical dietary levels, it is considered safe to consume.
