High-Purity Magnesium Silicate for Food Use
Product Name: Oil Filter Powder ( food grade Magnesium Silicate for catering stores)
CAS No.: 1343-88-0
Molecular Formula: xMgO·ySiO2·nH2O
Product Introduction:
A white, fine, and homogeneous solid powder. It exhibits good flowability, making it easy to pour and disperse, with low dust generation.
It has a smooth texture and no noticeable grittiness. With its large specific surface area and highly developed microporous structure, it efficiently adsorbs various impurities—such as free fatty acids, colorants, odor molecules, and polar polymers—much like a sponge.
It preferentially adsorbs polar harmful substances in oils or liquids while minimally adsorbing primary effective components (e.g., intact oil molecules). Highly chemically inert, it is insoluble in water and organic solvents, and does undergo chemical reactions under normal operating conditions, ensuring the safety of the treatment process and the stability of the treated materials (such as food).
Specification:

| 5 | Loss on Drying, % | ≤18 |
| 6 | pH Value (5% suspension) | 9.0-12.0 |
Operating Procedure
1.Uniform Dispersion: The powder should be sprinkled evenly and slowly into the liquid to be treated (e.g., hot oil) with gentle stirring to ensure full contact and adsorption of impurities.
2.Temperature Control: For frying oil purification, the optimal operating temperature typically ranges between 115°C and 135°C. Excessively high temperatures may cause further oil oxidation, while temperatures that are too low can reduce adsorption efficiency.
3.Adequate Filtration: After the adsorption process is complete, the magnesium silicate, along with the adsorbed impurities, must be thoroughly filtered out using suitable filtration equipment (e.g., filter paper, filter cloth) to ensure no residue remains in the final product.
