F-14 Phosphoric Acid Wood Powder Carbon – Food Grade Decolorization

Key Features

• High Decolorization Efficiency (≥210 mg/g methylene blue value)

  Developed mesoporous structure, excellent adsorption effect on macromolecular pigments and colored impurities, fast decolorization speed.

• Food Grade Safety Compliance

  Produced under strict food-grade management, holds food production license, meets the safety requirements of food and pharmaceutical production.

• Uniform Fine Particle Size (90% < 200 mesh)

  Large specific surface area in contact with liquid, fast adsorption rate, short treatment cycle and high production efficiency.

• Acidic pH (pH 2–5)

  Suitable for acidic liquid systems, maintains stable adsorption performance in acidic environment.

Applications

• Premium Beverage Decolorization: Wine, spirits and specialty juices contain polyphenolic pigments and colloidal haze that degrade visual appeal. F-14's phosphoric acid-activated mesopore structure selectively adsorbs these large color molecules while preserving desirable flavor compounds, achieving clarity that standard steam-activated carbons miss.

• Refined Sugar Processing: Raw sugar liquor requires ICUMSA color reduction to meet premium white sugar specifications. F-14's developed mesopores target sugar color molecules (1000–3000 Da) that micropore-dominant coal carbons cannot access, enabling single-pass decolorization to <45 IU.

• Pharmaceutical API Purification: Synthetic APIs and fermentation products carry colored byproducts and residual catalysts. F-14's ultra-high surface area and mild surface chemistry adsorb pigments and heavy metal residues without degrading active pharmaceutical ingredients.

• High-End Chemical Manufacturing: Fine chemicals with stringent color specifications require rapid, deep polishing. F-14's fast adsorption kinetics achieve equilibrium in 10–20 minutes, shortening batch cycles and improving throughput versus coarser powder alternatives.

Technical Advantages

• Phosphoric acid activation creates rich mesoporous structure, delivering better decolorization effect on macromolecular pigments than coal-based powdered carbon.

• Food-grade production management with complete qualification certificates, suitable for food and pharmaceutical production enterprises.

• Fast adsorption speed and short contact time improve production line efficiency and reduce equipment occupation.

• Tested in accordance with GB/T 12496-1999 national standard for stable quality and reliable performance.

FAQ

Q: What is the difference between wood-based phosphoric acid carbon and coal-based steam carbon?

A: Wood-based phosphoric acid activated carbon has more developed mesopores, better decolorization effect on macromolecular pigments, and is more suitable for food, sugar and pharmaceutical decolorization. Coal-based steam activated carbon has more micropores and is more suitable for small molecular pollutant adsorption in water and gas treatment. For water treatment scenarios, consider B-series coal-based powdered carbon.

Q: What is the recommended dosage for sugar decolorization?

A: Dosage usually ranges from 0.1% to 0.5% of sugar liquid weight, depending on raw material color value and impurity content. Laboratory jar testing is recommended to determine optimal dosage. For deeper decolorization, consider upgrading to F-16 or F-18.

Q: How should F-14 be stored?

A: Store in a dry, ventilated and clean warehouse, isolated from toxic, odorous and volatile substances. Pay attention to moisture-proof and fire prevention. For beverage applications requiring neutral pH impact, FHM physically activated wood carbon is an alternative.
