Food Grade Hydrated Silica for Milk Powder
Foreign Name: Sllicon dioxide
Chemical Formula: SiO2
CAS NO.: 7631-86-9
Silicon dioxide for anti-caking agent is a kind of white powder, which can solve the caking caused by moisture absorption and pressure of products, and has adsorption effect. It mainly used to add to granular or powdered food to prevent agglomeration and to keep it loose or free flowing.

Performance characteristics
Strict particle size distribution, large specific surface area.
2. High porosity, low bulk density.
3. High transparency, high reinforcement.
4. Strong adsorption capacity.
Main application: it is mainly used for food anticoagulant, thickener, stabilizer, essence and perfume, desiccant, etc. For example, egg powder, milk powder, cocoa powder, cocoa butter, powder flavor, medicine and so on.
