SORBSIL® R92: Food-Grade Silica Gel for Efficient & Safe Edible Oil Refining – The Industry Benchmark

In the edible oil refining sector, PQ Corporation’s SORBSIL® R92 has emerged as the preferred solution for global food processing enterprises, renowned for its exceptional performance and stringent safety standards. As a synthetic amorphous silica hydrogel, SORBSIL® R92 delivers efficient and eco-friendly solutions for degumming, bleaching, and impurity removal in edible oils through its unique formulation and technological advantages.

Core Advantages: High Adsorption Efficiency & Regulatory Compliance

Superior Adsorption Performance

Precision Impurity Removal: With a porous structure and high specific surface area (typically 150–600 m²/g), SORBSIL® R92 effectively adsorbs phospholipids, metal ions (Fe, Cu), pigments, oxidation products, and harmful substances (e.g., benzo(a)pyrene, aflatoxin B1) in edible oils.
Synergistic Effect: When used in combination with activated clay, it reduces clay dosage by 20–30%, minimizes solid waste generation, and preserves the natural color and sensory quality of oils.

Food-Grade Safety Certifications

Strict Compliance: Compliant with FDA (21 CFR 172.480), China GB 25576-2010, and EU food safety standards, ensuring no heavy metal or microbial contamination.
Green & Sustainable: Recyclable and reduces traditional process废渣 by 40%, aligning with T/COCIA 33-2024 green product specifications.

Stable & Reliable Technical Parameters

Key Indicators:
Silica content: 35.4% (specification: 28.0–38.0%)
pH value: 2.2 (25% solution), suitable for acidic/alkaline environments
Average particle size: 18.2 μm for optimal flowability and dispersibility
Carbon content: 1.3% (minimum 1.0%) to enhance adsorption efficiency

Applications: Full-Spectrum Edible Oil Refining

SORBSIL® R92 is widely used in:

Degumming & Deacidification: Stable performance at high temperatures (≤200℃) to improve oil purity.
Bleaching & Deodorization: Reduces activated clay usage while preserving natural nutrients.
Hazardous Substance Control: Efficiently adsorbs benzo(a)pyrene (0.1–0.3 mg/g) and aflatoxin B1 (0.05–0.15 mg/g) to ensure food safety.

Safe Operation & Sustainability

Storage & Transportation: Store in sealed, dry conditions (2–35℃) to prevent static buildup and dust generation.
Eco-Design: Contains no hazardous components (non-GHS classified), compatible with conventional wastewater treatment systems, and compliant with EU Waste Directive 2008/98/EC.
