Chemical Information
FooDB NameSilicon oxide
DescriptionSilica, also known as (sio2)n or 380, aerosil, is a member of the class of compounds known as metalloid oxides. Metalloid oxides are inorganic compounds containing an oxygen atom of an oxidation state of -2, in which the heaviest atom bonded to the oxygen is a metalloid. Silica is an odorless tasting compound and can be found in a number of food items such as pepper (spice), flaxseed, chicory, and tea, which makes silica a potential biomarker for the consumption of these food products.
