Silicon dioxide has a long history of use as a food additive without any detrimental health effects. Substances migrating to food from paper and paperboard productsĮFSA suggests re-evaluation of silicon dioxide Natural flavoring substances used in conjunction with flavors Principal section, free-flowing and anticaking agent in foods Microencapsulation of flavoring substances Inks for marking fresh fruits and vegetables Table 1 FDA clearances for silica substances as direct food additives 2 21 CFR Reference ![]() FDA regulation, levels of SAS cannot exceed 2% by weight of the food, and as an indirect additive, it can only be used in the amount required to produce the intended functional effect. It’s also used to manufacture materials such as adhesives and paper for food-packaging materials.Īs a direct additive, per U.S. Silicon dioxide also functions as a defoaming agent, carrier, conditioning agent, chillproofing agent in malt beverages (like beer) and filter aid. This allows powdery products to remain free-flowing, and other products easy to separate. In powdered foods, the silica clings to the particles of the foods and prevents them from clumping. Silicas exist as white, fluffy powders that are produced through a wet process, yielding silica or silica gel, or a thermal route, yielding pyrogenic (fumed) silica.

Silicon should not be confused with silicone, a plastic material that contains silicon and other chemicals used to make breast implants, medical tubing and other medical devices. It’s also naturally found in water and plant-based foods, especially cereals like oats, barley and rice. 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.ĭerived from naturally occurring quartz, silicon is the most abundant mineral in the earth’s crust.
