Product Description
Industrial /Food Grade Silicon Dioxide
silicon dioxide products for food additives have been tested to conform to the food additive standard of the People's Republic of China (GB25576-2020), and a product hygiene license has been issued. Especially, it has ultra-low treatment for heavy metals (Pb, Sb, etc.) and bacteria. It is mainly used as food anti caking agent, thickening agent, coagulant, carrier of essence, spice and active component, quality improver, oil adsorbent, pharmaceutical auxiliary and clarification filter aid.
The silicon dioxide used for FINE-SIL520 food additive has a large specific surface area, which enables it to act as a spacer between the particles of powder materials, and at the same time promotes the free flow of powder materials. Its moisture absorption performance is great, and it also enhances the anti caking effect and adsorption effect. It can be used as anti caking agent in essence, spices, instant noodle soup, etc.
