Silicon dioxide, also known as silica, is a naturally occurring mineral compound widely used in the food industry as a processing aid. Its primary function is as an anti-caking agent that prevents clumping and improves the flow characteristics of powdered and granular food products.
Food-grade silicon dioxide is produced in amorphous form, which is distinct from crystalline silica and considered safe for consumption. It is effective at very low usage levels, typically 1-2% of the product weight, and does not affect taste, color, or nutritional value. Silicon dioxide also serves as an adsorbent and carrier for flavors, vitamins, and other active ingredients.
