PURESTAR food-grade activated carbon provides safe, efficient purification solutions for sugar refining, beverage production, amino acid processing and food packaging.All products meet international food safety standards, ensuring product clarity, taste stability and compliance with regulatory requirements.
1.Sugar Decolorization
Cane and beet sugar refineries require high-performance decolorization to improve product quality and meet market standards.PURESTAR's wood-based powdered activated carbon and granular activated carbon are specially optimized for sugar refining scenarios, focusing on color removal, ash reduction and inversion control.
Key performance indicators:
ICUMSA color reduction: from 800–1,500 IU to < 45 IU (meets premium sugar quality standards)
High mesopore volume: efficiently adsorbs large melanoidin and carameline molecules
Food-grade compliance: fully meets FDA 21 CFR 173.25 and EU 231/2012 safety standards
2.Corn Syrup Decolorization
High-fructose corn syrup (HFCS) and glucose syrup production involves multi-stage purification to ensure clarity and stability.PURESTAR activated carbon plays a key role in ion exchange polishing processes, targeting specific impurities in syrup. It efficiently removes:
Protein residues affecting syrup viscosity and appearance
Hydroxymethylfurfural (HMF) that causes color degradation
Color precursors to prevent post-production darkening
The purified syrup maintains consistent quality for confectionery, beverage and baked goods applications, extending shelf life and reducing product rejection rates.
3.Beer & Beverage Production
Breweries and soft drink manufacturers demand strict water quality and product stability control.PURESTAR food-grade activated carbon is trusted by leading brands including Coca-Cola, Master Kong, and JDB, providing comprehensive purification solutions for beverage production.
Core application scenarios:
Dechlorination of brewing water: protects yeast viability and avoids off-flavors
Color and haze stabilization: ensures clarity in clear beverages (soda, bottled water, juice)
Off-flavor removal: eliminates diacetyl, acetaldehyde and oxidation byproducts
CO₂ purification: removes VOCs and odors from recovered fermentation gas
4.Amino Acids Purification
Fermentation-derived amino acids (lysine, glutamate, tryptophan) require rigorous decolorization and impurity removal before crystallization.PURESTAR's acid-washed, low-metal activated carbon is engineered for high-purity amino acid processing. Key advantages for amino acid purification:
Removes pigments and pyrogenic substances without introducing contaminants
Low metal content: avoids affecting amino acid biological activity and formulation stability
Compatible with fermentation process parameters: maintains performance in mild acid/alkali environments
It helps manufacturers meet pharmaceutical and food additive quality standards, improving product yield and purity.
