Fine-sil520 series silicon dioxide products for food additives have been tested to meet the food additive standard of the people’s Republic of China gb25576-2020, and the product hygiene license has been issued. Especially for heavy metals (Pb, Sb, etc.) and bacteria. It is mainly used as food anticancer agent, thickener, coagulant, flavor and active ingredient carrier, quality improver, oil adsorbent, pharmaceutical excipient and clarifying filter aid.
Fine-sil520 silicon dioxide for food additive has a large specific surface area, so that it can act as a spacer between the particles of powder material, promote the free flow of powder material, its moisture absorption performance is great, and enhance the anti caking effect and adsorption. It can be used as food additives in flavor, spice, instant noodles, soup and other foods.
