Onion And Silicon Dioxide

Onion is a common vegetable known for its pungent flavor and aroma. It is typically dried and ground into a powder for use as a seasoning. Silicon dioxide is a naturally occurring compound found in sand and quartz, often purified and used as an anti-caking agent.

Onion powder provides the flavor of onion in a dry, shelf-stable form. Silicon dioxide is added to powdered foods to prevent clumping and ensure free flow. They are often found together in seasoning mixes, salts, and marinades.

Onion powder is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. Silicon dioxide is also GRAS for use as an anti-caking agent. Neither ingredient has specific health concerns associated with their typical use in food. JECFA and EFSA have evaluated both, and they are permitted for use in many countries.
