What specific grade of activated carbon is used for food, beverage, and sugar decolorisation?

Food, beverage, and sugar decolourisation typically require high-purity, acid-washed food-grade granular or powdered activated carbon (derived from steam-activated wood, coconut shell, or select bituminous coal) that complies with the Food Chemicals Codex (FCC) and NSF/ANSI Standard 61.

• Purity & Leaching Standards: Must feature extremely low ash content and strict heavy metal limits (e.g., lead, arsenic, iron) to prevent chemical leaching into consumable syrups.

• Pore Structure: Requires a balanced mesopore-to-macropore distribution to effectively adsorb large organic color bodies and high-molecular-weight impurities found in cane sugar and beverage syrups.

• Acid-Washed Treatment: Acid-washing removes residual soluble ash and neutralizes pH, ensuring the carbon does not alter the taste, clarity, or chemical balance of the final product.
