RUNSE QUDIAO
Food Grade Adsorbent Silica
Food industry adsorption material, applicable in oils, beverages, alcoholic beverages, and food ingredients*
1. Food-grade compliance, covering major global markets**
White uniform powder meeting GB 25576-2020, FDA (21 CFR), EU E551 and JECFA standards. Heavy metals, arsenic and lead are strictly controlled, allowing direct contact with food and food ingredients.
2. High-purity silica, chemically inert and safe**
High SiO₂ content. Inert to acids, alkalis and salts at room temperature (except strong alkali and hydrofluoric acid). Introduces no off-flavor and does not alter the original taste or color of food.
3. Mesoporous structure, large surface area, high adsorption efficiency**
Controllable pore size (typically 8–15 nm) with high specific surface area. Selectively adsorbs polar impurities such as phospholipids, soaps, free fatty acids, proteins, polyphenols, metal ions and pigments.
4. Customizable particle size for different processes**
Available in coarse, medium and fine grades. Can be dosed directly as an adsorbent and filtered afterward, or pre-coated on filter cloth/leaf filters as a filter aid, balancing adsorption performance with filtration throughput.
5. Good thermal stability, wide process compatibility**
Stable from room temperature up to 200°C. Suitable for hot oil refining, hot beverage treatment and around pasteurization steps, without decomposition or impurity release.
6. Wide application range**
- Edible oil refining**: pre-treatment adsorption in degumming, deacidification and bleaching
- Frying oil management**: filtration of hot frying oil in service to extend oil life
- Beverages & alcoholic drinks**: clarification and polyphenol/protein stabilization for beer, wine and fruit juices
- Food ingredients**: anti-caking and flow improvement for milk powder, cocoa powder, spices and seasonings
7. Easy filtration, low product carry-over
Balanced particle size distribution for fast filtration and a clear filtrate. Weak adsorption toward target products (oil, beverage, wine) minimizes valuable product loss.
8. Easy handling and storage
Free-flowing powder, low caking tendency and low dusting. Packed in standard paper bags or bulk bags. Long shelf life under dry, cool conditions; no special storage required.
