Food-Grade Silica 5μm
Classification :
Anti-Caking Silicon Dioxide
Keywords :
Food-Grade Silica 5μm
PRODUCT DETAILS
1. Product Advantages
This product is food-grade silica with a precise particle size of 5μm, crafted into an ultra-fine particle size specification via molecular-level technology. It complies with the international standards of GB 25576-2020, FDA, FCC and USP, featuring high purity (silica content ≥99%) and ultra-low heavy metal residues (Pb ≤0.1mg/kg, As ≤1ppm), which are far below the international safety limits.
The 5μm ultra-fine particle size delivers core features of high dispersibility and no gritty texture. It is inert to all food ingredients, boasts excellent anti-caking performance and an over 40% improvement in powder flowability. Ideal for the processing and storage of fine powder foodstuffs, it does not affect the original taste and flavor of food throughout the production process and is fully compatible with large-scale manufacturing.

6. Frequently Asked Questions
Q: Will adding this product affect the taste of food?
A: No. With the 5μm ultra-fine particle size and low dosage (≤1%), the product disperses completely in the mouth with no gritty texture and does not alter the original taste of food.
Q: Does it comply with Halal/Kosher food production requirements?
A: Yes. The product is certified by SHC HALAL and OU KOSHER, and no animal-derived raw materials are used in the production process.
Q: How to determine the optimal addition ratio?
A: Our technical team can provide exclusive guidance according to the characteristics of food categories, and the optimal dosage can also be determined through accelerated caking tests to optimize the formula.
