PRODUCT DETAILS
1. Product Description
500-mesh fine-particle food-grade silicon dioxide (E551) is refined by precipitation method, complying with GB 25576-2020, USP, FCC, FDA 21 CFR and other international standards, with SiO₂ content ≥98%. Focusing on flow aid and supplemented with anti-caking performance, its fine particle size has excellent dispersibility and no gritty texture. Its heavy metal residues are far lower than international limits, suitable for the flow aid and anti-caking needs of fine-powder food, and in line with global high-end food production specifications.

3. Product Application
Suitable for ultra-fine particle food powders, including whey protein powder, meal replacement powder, nutritional supplements, high-end condiments, etc. It corely optimizes the filling fluidity and dispersion uniformity of powder, solves the problems of fine-powder agglomeration and large filling error with a filling error ≤±1%. It disperses completely in the mouth after addition with no foreign body sensation, and does not affect the taste and nutritional components of food.
4. Factory Advantages
We have a dedicated GMP standardized workshop for fine-particle products, equipped with laser particle size analyzers, atomic fluorescence spectrophotometers and other high-end testing equipment for exclusive particle size and purity testing, with batch-to-batch particle size deviation ≤±3μm. Certified by ISO22000, the 10,000-ton production line ensures stable supply with a lead time of 5-10 days, and we can provide adaptation solutions for high-end food scenarios.
5. Shipping & Packaging
Standard packaging: 10/15/20kg food-grade vacuum moisture-proof bags with double protection, preventing fine powder from moisture absorption and agglomeration.
Storage & transportation: Seal and store in a cool and dry place, avoid high temperature and humidity; non-hazardous chemical, shippable worldwide; 24-month shelf life.
Marking specification: Marked with food-grade, fine particle size, purity and addition limit; provide detailed Chinese-English physicochemical instructions.
6. FAQs
Q: Will there be gritty or foreign body sensation after addition?
A: No, the 500-mesh ultra-fine particle size design with excellent dispersibility can disperse completely in the mouth without any sensory discomfort.
Q: Is it suitable for agglomeration-prone fine powders such as high-protein powder?
A: Yes, the fine particle size can effectively break the agglomeration force of fine powder, optimize dispersibility and fluidity, and prevent caking during long-term storage.
