Advsil® Precipitated Silica Food Grade

Chemical name: SILICON DIOXIDE
Molecular formula: SiO2 * nH2O
Chemical structure: O=Si=O



Precipitated silica food grade is physiologically inert. It has excellent chemical stability. And does not accumulate in human body. It has been widely used in the food and medicine. Food grade silica can prevent caking problem in food products. Caking usually is due to moisture absorption, or formed under pressure. Silica is of strong adsorption performance, being an excellent flow promoting agent.

Widely used: chicken powder, milk, creamer, instant coffee, cocoa products, dehydrated egg products, sugar, powdered soup, dehydrated vegetable powder, flavoring.

Offers the following advantages for these products:
