PRODUCT DETAILS
1. Product Description
325-mesh medium-particle food-grade silicon dioxide (E551) is produced by precipitation method, complying with core global standards such as GB 25576-2020, USP, FCC, FDA and EFSA, with SiO₂ content ≥97%. It has excellent dual performance of anti-caking and flow aid; the medium particle size balances spatial barrier and feeding fluency, making it an all-round additive for the food powder industry. Its heavy metal residues are lower than international limits, suitable for global mid-to-high-end food production scenarios.
