The structure of silica

Depending on the structure of silica, it can appear as a clear, odourless, crystalline or amorphous powder (sometimes called silica powder). As the USDA describes, amorphous silica has "highly unique physical and chemical properties and potential as an additive for various processing industries." For example, it has a small particle size, a high specific surface area, and the ability to gel and thicken. The other factor that makes silica unique is its solubility. Silica is insoluble in water or organic solvents. In addition to its use in food supplements and cosmetics, silica produces cans, impermeable membranes, paints, silicone rubber, polyester compounds, dental formulations, lotions, dry pesticides, soil amendments, and lawn soil. Silica production is a form of "nanotechnology," which involves making material into tiny particles between 1 and 100 nanometers. This alters the material's physical, chemical and biological properties and functions. While nanotechnology in food processing may help improve the taste, colour, appearance, uniformity and texture of food, it may also alter the absorption and excretion of materials in the human body.
