What Is Food Grade Calcium Carbonate (FCC)? Food Grade Calcium Carbonate (FCC) is a ultra-purified, edible-grade mineral specifically processed to meet stringent safety standards for human consumption. With ≥99% CaCO₃ purity, heavy metals <1ppm, and zero microbial contamination, FCC serves as a critical ingredient in pharmaceuticals, nutraceuticals, and food products. Key Features: Certifications: FDA 21 CFR 184.1409. EFSA, USP-NF, EU 10/2011. Safety: Non-GMO, allergen-free, and Kosher/Halal certified. Versatility: Neutral taste, fine particle size (D50 5–20μm), and excellent compressibility. How Is Food Grade Calcium Carbonate Produced? 1. High-Purity Sourcing Raw Materials: Select limestone from quarries with geological purity reports (Fe₂O₃ <0.01%, SiO₂ <0.1%). Exclusion Zones: Mining sites located away from industrial pollutants. 2. Pharmaceutical-Grade Processing Steps: Multi-Stage Washing: Remove impurities using deionized water. Precision Milling: Jet mills produce 5–20μm particles (ISO 13320 compliant). Sterilization: Gamma irradiation or heat treatment to meet USP <61> microbial limits. Packaging: Nitrogen-flushed, food-grade polyethylene bags. Quality Controls: Heavy Metals: ICP-MS tested for Pb, Cd, As, Hg (<1ppm total). Microbial: TAMC <100 CFU/g, TYMC <10 CFU/g (USP <2021>). Technical Specifications of FCC Parameter Specification Test Method CaCO₃ Purity ≥99% EDTA Titration Particle Size (D50) 5–20 μm Laser Diffraction Loss on Drying ≤0.5% USP <731> Heavy Metals <1 ppm ICP-MS Microbial Count TAMC ≤100 CFU/g USP <61> Customization: Adjust particle size (3–50μm), bulk density (0.4–0.8 g/cm³). Why Choose Food Grade Calcium Carbonate? Uncompromised Safety: Pharma Compliance: Meets USP/EP for direct compression tablets (e.g., antacids, calcium supplements). Food Safety: GRAS-affirmed, ideal for baking powders, dairy alternatives, and infant formula. Functional Performance: Tablet Binding: 20–30% FCC loading improves hardness (≥50 N) and disintegration (<15 mins). Acid Neutralization: Rapid reactivity in antacids (pH adjustment within 2 mins). Supply Chain Transparency: Batch-specific COA with traceability to mine origin. Supports FSSC 22000 and BRCGS audits. Applications of Food Grade Calcium Carbonate 1. Pharmaceutical Tablets Antacids: 500–1000 mg…
What Is Activated Calcium Carbonate? Activated Calcium Carbonate is produced by surface coating the Precipitated Calcium Carbonate slurry with Fatty Acids (Stearic Acid) and Titnate Coupling Agent then filtering and drying of the coated PCC slurry to produce ACC powder. Unlike untreated calcium carbonate, ACC reduces interfacial tension, enhances mechanical properties, and enables higher filler loading—making it a game-changer for cost-sensitive, high-performance applications. Key Features: Surface Treatment: Stearic acid (1–3%), titanate, or silane coatings. Enhanced Compatibility: Optimal bonding with plastics, rubber, and resins. Purity: ≥98% CaCO₃, heavy metals <10 ppm (ICP-MS verified). How Is Activated Calcium Carbonate Produced? 1. Dry Surface Modification Steps: Pre-Drying: Heat CaCO₃ to 100–120°C to remove moisture. Coating: Spray stearic acid (1–2% by weight) in high-speed mixers. Curing: Heat to 80°C for 30 minutes to ensure uniform coverage. Advantages: Low energy consumption (≤15 kWh/ton). Oil absorption reduced to 20–25 g/100g (vs. 35–40g for untreated CaCO₃). 2. Wet Surface Modification Steps: Slurry Preparation: Mix CaCO₃ with water (30–40% solids). Reactor Treatment: Add titanate coupling agent (0.5–1%) under pH control. Filtration & Drying: Centrifuge and spray-dry to free-flowing powder. Advantages: Higher coating uniformity (≥95% coverage). Ideal for nano CaCO₃ activation (50–100nm). Technical Specifications of Activated Calcium Carbonate Parameter Specifications Testing Method Particle Size (D50) 1–10 μm (adjustable) Laser Diffraction Activation Degree ≥90% TGA Weight Loss Analysis Oil Absorption ≤25 g/100g ISO 787-5 Moisture Content ≤0.3% Oven Drying (105°C) pH Value 8.0–9.5 pH Meter (10% suspension) Custom Options: Coating agents (stearate, titanate, silane). Particle size (0.5–15 μm), packaging (25kg bags, bulk silos). Why Choose Activated Calcium Carbonate? Core Advantages Superior Polymer Compatibility Plastics: Enables 50–70% filler loading in PVC pipes, reducing costs by 20–30% while maintaining impact strength (ASTM D256). Rubber: 40% replacement of carbon black in tires, improving tear resistance by 15% (ASTM D624). Process Efficiency Reduces mixing time by 25% in polymer compounding (Brabender torque…
