Moreover, SiO2 nanoparticles have been reported to induce activation of the NLRP3/ASC inflammasome and the secretion of inflammatory cytokines in macrophages [18,22]. These findings suggest that ingested SiO2 nanoparticles can potentially increase intestinal inflammation. Summary. Silicon dioxide (E 551) is authorized as a food additive in the European Union (EU) following Annex II and Annex III to Regulation (EC) No 1333/2008 on food additives, and specific purity criteria are defined in the Commission Regulation (EU) No 231/2012. Also called silicon dioxide (SiO2), it is composed of Silicon and oxygen, which comprise much of the Earth's crust. Silicon dioxide is widely used as an anticaking agent in flour-based baking mixes. Silicon dioxide, also known as synthetic amorphous silica (SAS), is widely used in food products as a thickener, anticaking agent, and carrier for fragrances and flavors.
Silica sand, also known as quartz, white, or industrial sand, comprises two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral. Silicon dioxide is mostly obtained by mining, including sand mining and purification of quartz. Quartz, or crystalline silica, is suitable for many purposes. At the same time, production via chemical processing is required to make a purer or otherwise more suitable product (e.g., more reactive or with lower particle size). Therefore, before silicon dioxide can be used in feed for organic livestock, it must be determined whether it is synthetic. Only nonsynthetic, mined mineral versions of silicon dioxide can be used in feed for organic livestock.
