The production of silicon dioxide is one form of “nanotechnology,” which encompasses taking a material and making it into very tiny particles, with dimensions between one and 100 nanometers.
In addition to being used in foods supplements and cosmetics, silica is utilized in the production of cans, impermeable films, paints, silicone rubbers, polyester compounds, dental formulations, emulsions, dry pesticides, soil conditioners and turf soil. Silicon dioxide is not soluble in either water or organic solvents. Something else that makes silica unique is its solubility. For example, it has a small particle size, high specific surface area, and gelling and thickening abilities. Helps in processing of wine and gelatin productionĭepending on silicon dioxide’s structure, it can appear as a transparent, tasteless, crystal or an amorphous powder (sometimes called silica powder).Īmorphous silica has a “highly unique physical and chemical properties and potential as an additive in a variety of processing industries,” as described the USDA.Helps carry and distribute flavoring oils.What is silicon dioxide used for in foods and supplements? According to the USDA, silicon dioxide has properties that give it the following functions in foods and supplements: Food and Drug Administration (FDA) describes it, “it increases speed of dispersion, keeping the food particles separated and permitting the water to wet them individually instead of forming lumps.” It’s most often found in granular or powder products, because as the U.S. Silicates are also present in a variety of plant foods included in the human diet, including vegetables and cereal grains, such as leafy greens, peppers, beets, sprouts, rice and oats.īecause it has the ability to block moisture absorption and prevent ingredients from clumping/caking together, silicon dioxide is used in food products to help retain their texture. beer (it is removed from the beer by filtration prior to final processing).Which foods contain silicon dioxide? You’ll find it in small amounts added to foods, such as: It’s typically manufactured by vapor phase hydrolysis. Synthetic amorphous silicon dioxide is the type most often used as a food additive. This type is found in supplements because it has anti-caking, adsorbent, disintegrant and glidant effects. Colloidal silicon dioxide, which is used in tablet-making.This is the type most often used as an anti-caking agent to keep powdered foods free-flowing and to prevent moisture absorption. This also forms diatomite, diatom silica or diatomaceous earth, which is made from deposits that accumulate over time in the sediment of rivers, streams, lakes and oceans. Amorphous silica, found in the earth’s sediments and rocks.This isn’t the form used in foods and can be problematic when inhaled over long periods of time. Quartz actually comprises a high percentage of the Earth’s crust, so this type is widely available. Crystalline silica, which is usually obtained from mining quartz.Silica/silicon dioxide comes in several forms, depending on how it’s manufactured, including: It’s also sometimes referred to as silicic anhydride or silicate. Silicon dioxide goes by the common name silica. What is silicon dioxide made of? It’s composed of a combination of silicon (Si) and oxygen (O), which is why it has the chemical formula SiO2. This compound has a variety of uses in industries ranging from food and cosmetics to construction and electronics.

It is also found in some organisms and animals, the human body (it’s a component of human ligaments, cartilage and musculature), plus some plants (especially grains) and in drinking water.Īdditionally, it’s created in labs and used as a common food additive, found in things like baking ingredients, protein powders and dried spices.
It can be obtained from mining and purifying quart. Silicon dioxide is a compound that’s naturally found in the earth’s crust in a crystalline state. What Is Silicon Dioxide? Where Is It Found Naturally? The type found in our food supply has been shown to be safe in studies, however ongoing exposure to certain types of silicon dioxide can pose a risk to people who work in mining, construction and steel industries. What is silicon dioxide exactly, and is it safe? Also known as silica, this compound exists in nature in the form of certain minerals and is also man-made in labs to be used in foods, supplements and cosmetics. One such additive is silicon dioxide, which the ability to help prevent ingredients from becoming moist and clumping together. In order to improve the texture and shelf life of granular and powdered food products, such as protein powders and seasonings, anti-caking additives are often used.
