SAS in foods
Synthetic Amorphous Silica (SAS) consists of silica nanoparticles that clump together to form bigger agglomerates (in the micrometre scale). SAS is present in various foods such as coffee creamers and prepackaged ingredients for making soups, sauces, and seasonings. It is added in the form of food additive E551, which is an anti-caking agent. To enable a proper assessment of the potential health risks of nanosilica in food products, more information is needed on its uptake into the body and potential accumulation in tissues. Together with partners such as RIKILT and NVWA, RIVM is examining the potential health risks of SAS in foods.
