Food-Grade Diatomaceous Earth

Food-Grade Diatomaceous Earth

Food-grade diatomaceous earth does not imply direct consumption, but rather denotes a purified form of diatomaceous earth that complies with national food additive standards. Produced through calcination processes, this specialized material retains the characteristic porous microstructure that provides exceptional adsorption and filtration capabilities.In food processing applications, it effectively removes suspended solids, colloids, and microorganisms from liquid food products including alcoholic beverages, fruit juices, and edible oils, ensuring optimal clarity and purity. The material demonstrates complete food safety with stable chemical properties that preserve the original flavor profiles and nutritional content of filtered products.Widely utilized in beer, wine, syrup, and condiment production, food-grade diatomaceous earth combines environmental sustainability with cost-effectiveness. Its unique properties make it an ideal choice for modern food industries seeking to implement clean production processes while maintaining stringent quality standards. The material's inert nature and compliance with international food safety regulations further reinforce its position as a trusted filtration aid in global food manufacturing.

What Are The Advantages Of Food-grade Diatomaceous Earth？
1.Food-Safety Certified Material,Food-grade diatomaceous earth (not for direct consumption) meets international safety standards including FDA and EU 10/2011. Composed of natural silica (SiO₂≥85%), it is non-toxic and chemically inert, ensuring safe contact with edible liquids without reacting with food components. 2.2.Stringent Impurity Control,With strict limits on heavy metals (Pb≤4ppm, As≤5ppm), it complies with China's National Food Safety Standard (GB 14936-2012), guaranteeing purity for food-processing applications.High-Efficiency Purification,Removes wax particles in honey processing,Adsorbs aflatoxin B₁ in edible oil refining (detoxification rate >90%) Selective Adsorption Without Compromising Quality 3.Food-grade diatomaceous earth exhibits intelligent filtration characteristics - it selectively adsorbs impurities while preserving essential flavor compounds and nutrients. This unique property is particularly valuable in premium applications such as whiskey aging filtration, where it effectively removes unwanted particulates while retaining delicate ester aromas that contribute to the spirit's complex flavor profile. Similarly, in juice production processes, it maintains up to 95% of the original vitamin C content while achieving superior clarification. This precision filtration capability makes it the preferred choice for quality-conscious food and beverage manufacturers who demand both purity and product integrity.
