Description
Food & Beverage Grade Diatomaceous Earth: High-Precision Filter Aid for Edible Liquids
Food & Beverage grade diatomaceous earth is a natural, non-toxic mineral derived from fossilized diatoms, formed through millions of years of aquatic sedimentation. Its core component is silicon dioxide (85%-92%), with trace alumina (2%-4%) and iron oxide (0.5%-1.5%)—all within FDA safety limits. As a professional filter aid for edible liquids, it undergoes strict purification (acid washing + high-temperature calcination) to remove heavy metals (Pb≤0.05mg/kg, As≤0.03mg/kg) and harmful impurities.
Microscopically, it features a honeycomb porous structure with 85%-90% porosity and a specific surface area of 30-60 m²/g, enabling it to capture particles as small as 1-6 microns—far exceeding the precision of sand or activated carbon filters. It effectively removes suspended solids, bacteria, algae, and colloids from beer, wine, edible oil, fruit juice, and drinking water, while preserving the original flavor and nutrients of the liquid (no chemical leaching). Chemically stable, acid-resistant, and odorless, it is compatible with all food processing conditions and meets global food safety standards (EU EC 1935/2004, US FDA 21 CFR).
Hebei Hezhen Industrial Co., Ltd. is a trusted supplier of food-grade diatomaceous earth for filtration. Our products have moisture ≤0.8%, ignition loss ≤5%, and uniform particle size—ensuring no filter clogging and stable flow rates. We offer customized mesh sizes (325-1250 mesh) and bulk supply, with products exported to Europe, America, Australia, and Southeast Asia, providing reliable filtration solutions for breweries, oil refineries, and beverage factories.
